Professor of Veterinary Physiology New York State Veterinary College, Cornell University FOURTH EDITION REVISED AND ENLARGED CARPENTER & CO. ITHACA. N. Y. 1912 COPYRIGHT. 1912 BY CARPENTER & CO. <^ £CI,A3ia272 PREFACE TO THE FOURTH EDITION. The desire of the writer to place before the veterinary students and profession a convenient and ready reference to information concerned with dosage, prescription writing, incompati- bility and antidotes for poisons, etc., has ap- parently been fulfilled by the call for a fourth edition. In the present edition a few tables and points of physiologic interest have been added, which, it is hoped, will increase the value of the work. Care has been taken to minimize errors as far as possible. Wherever they have crept in, the writer would be grateful for any informa- tion to that effect and furthermore would wel- come any suggestions for improvement. Jan. 1912. P. A. P.

Although this is frequently done in experimental work, the practice is attended with so much incon- venience when applied to the routine of the practitioner that the system is, for ordinary purposes, regarded as impracticable. A more or less arbitrary method is adopted by fixing tlie amount to be given to the different animals. Except, perhaps, in the case of powerful medi- cines or poisons, there is considerable latitude allowed in the amount of the doses. In veteri- nary practice the dose for the horse is com- monly taken as the standard and the doses of the other domestic animals may be reckoned from this. As for example: If the dose for the horse is 1 (Say 2 ounces) the doje f< r the cow would be H ( Sheep and goat \ ( Swine | ( Dog j\ ( Cat 3V ( In general the dose for the dog is about the same as the human dose, but the size of the dog must be considered. Reckoning from the dose for the dog or man as the standard; the pig would take twice as much, the sheep and goat three times as much, the horse sixteen times as much and the cow twenty-four times as much. The dose for the cat is usually one-half as much as for the dog. In many cases the dose for the horse and cow would be the same; the higher dose for the cow is usually recommended on the 8 ) 3 drams) 2 1 ) i ) 6 ground of a slower rate of absorption because of the compound stomach and a larger mass of food with which the medicines mix before ab- sorption may occur. In the list of doses which follows, the horse and cow have been placed in the same group, and the sheep and the swine have been placed in a group by themselves. The dose given in either case is the average dose, but from the explanation just given, the dose, in most in- stances, may be increased somewhat for either the cow or the sheep. In a general way the doses of different prepa- rations of drugs for the horse may be given upon the following basis. If there is error in this classification, it is upon the safe and con- servative side of too little rather than too much. Poisons and powerful medicines are, of course, an exception. Fluidextracts one fluidram Powders (not alkaloids) one dram Tinctures one fluid ounce Hypodermics of alkaloids are given usually at one-half the dose by mouth. Intravenous doses one-half or two-thirds of the hypodermic dose. Rectal doses should be the same as those given by the mouth. In the following tables the doses are intended for administration by mouth unless otherwise stated. On account of idiosyncrasy or individual sus- ceptibility, it is safer in the case of new or powerful drugs, to try the minimum doses first and if the physiologic effects are not produced, gradually lead up to the maximum doses.

PRESCRIPTION WRITING. A prescription may be defined as a written order or formula of ingredients, with directions to the compounder and instructions for the guidance of the patient. The term is derived from the Latin prae "before" and scriptum "written." It is generally conceded that Latin is the best language for prescriptions. It is a dead lan- guage and therefore not subject to the varia- tions which modern languages are continually undergoing. It is unchangeable the world over and a prescription written in this country may be put up in a foreign country with equal fa- cility. The Latin name of a drug is distinctive and as a rule means only a given drug and am- biguity is therefore avoided; in some of the modern languages a given drug may have a va- riety of names, and in some cases the same name is applied to different drugs. Finally there is an element of secrecy which is often desirable to prevent the patient or general pub- lic from knowing what has been prescribed and there is less likelihood of "self doctoring" or using the prescription for some disorder for which it is not applicable. 69 A true principle of a prescription as based upon a maxim of Ascleplades, curare cito, tuto et jucunde, is to cure quickly, safely and pleas- antly. According to this rule the typical pre- scription should contain, in the first place, an ingredient which is expected to relieve or cure the patient and is therefore called the basis; second, an ingredient designed to assist the action of the basis so that it may do its work more quickly, designated as the adjuvant; third, a substance intended to correct or modify any undesirable or injurious effect of the basis or adjuvant, or to cause it to act more safely than if used alone, and on this account is re- ferred to as a corrective; and fourth, a sub- stance may be added, which will give such form and consistence to the preparation as to make it pleasant and at the same time dilute tne whole preparation to the proper proportion for meas- uring out • the intended doses, termed the vehicle. The following table will express the idea in a concrete form : Curare (Cure) with the (Basis). Cito (Quickly) " " (Adjuvant). Tuto (Safely) " " (Corrective). et Jucunde (Pleasantly) " " (Vehicle). In Veterinary practice jucunde is generally ignored as the patients do not take to the idea of medicines pleasantly as a rule, and the prin- cipal use of the vehicle is to dilute the ingredi- ents to the proper dosage. In addition to the ingredients other data are given, such as the date, name of patient, direc- 70 tions to the compounder and to the patient, and the signature of the physician. Taking the pre- scription in its entirety it may be divided as fol- lows: Superscription or heading includes the symbol Rr (Recipe) the first direction, "take." Inscription, the ingredients, or basis, adjuvant, corrective and vehicle. Subscription, the directions to the compounder. Transcription or Signature, the directions to the patient and the signature of the prescriber with the date. In a simple prescription the basis may be the only ingredient. In a compound prescription (with two or more ingredients), the agents added may be neither adjuvant nor corrective and yet be a good prescription. It is desirable, however, to keep the consideration of a "typical" prescription in mind. Unusual doses of a powerful drug may be re- fused by the pharmacist unless some indication is made that the dose is intended. This is usu- ally done by underscoring the dose, or better yet writing after it the abbreviation q. r. (Quan- tum Rectum. ) Practice makes proficiency in prescription writing. The prescription needs study as much as any other subject and the student should practise the writing of it, independently of any demand, simply for the experience. To the beginner the following general hints from Sollman should be of benefit: "When writ- ing a prescription for a given condition, put down, first, the name of the best remedy. Ask yourself whether there is any other drug which may be employed to aid this. Put this down also. Then consider in which form the medi- cine should be administered, whether as liquid, powder, salve, etc. This will usually determine which preparation of the ingredient is to be employed. Put this down also. Then ask your- self what may be added to render the mixture agreeable to the patient. When this is written down, all the ingredients will be represented. Now look over this carefully and see that there are no incompatibilities and that the constitu- ents are soluble if the mixture is to be a liquid. Next insert the endings. Write the directions to the dispenser. Now consider the doses of the mixture, teaspoonful, tablespoonful, etc., the approximate number of doses, and from these calculate the size of the mixture. It should be considered how many doses are to be taken each day (on the basis of sixteen hours a day) ; this, multiplied by the number of days, gives approximately the size of the mixture. Then write the directions to the patient. Now consider how much of each ingredient is to be given at each dose, multiply by the number of doses, and write down the quantity. This fin- ishes the prescription. Look over the result carefully in the same order."

The metric system is coming more and more into use so that a knowledge of it will in a few years be indispensable. The beginner should learn to write his prescriptions in both the apothecary and metric systems. The ingredients of a prescription are fre- quently abbreviated and although writing out in full is better there is no special objection to the former practice if there is no ambiguity in the abbreviations. Grievous errors have oc- curred in this way and too much caution cannot be exercised in making the meaning clear, so that the most ignorant drug clerk may avoid error. Numerous examples of ambiguous abbrevia- tions might be given, but a few mentioned be- low will serve as examples: 73 Acid Uycl. may mean either hydrobromic, hydro- chloric, hydriodic, or hydrocyanic acid. Chlor. may mean chlorine, chloroform, chloral hydrate, chlorate or chloride. Hydr. Chlor. may mean calomel, corrosive sub- limate, hydrate of chloral, or hydrastin hydrochloride. The context may often assist in arriving at the correct meaning of the abbreviation but it is not safe in all cases to depend upon this. A limited knowledge of Latin will serve to en- able one to write prescriptions properly. The student becomes familiar with the Latin names of drugs if he has studied his Materia Medica faithfully. The principal difficulty that he en- counters is in making the changes necessary for the correct grammatical wording to the dis- penser and the grammatical ending of the in- gredients and their quantities. The following simple rules taken from Mann, will, it is believed, enable one not previously ac- quainted with Latin, to write proper prescrip- tions with correct endings. Rule I. The noun expressing the name of the medicine is put in the genitive case, when the quantity of it to be used is expressed. Rule IL If no quantity is expressed, but only a numeral adjective follows, the noun is put in the accusative. Rule III. The quantity is put in the accusa- tive case governed by the imperative Recipe. Rule IV. Adjectives agree with these nouns in gender, number and case. For every day practice the accusative of the 74 quantity is seldom written out but is usually ex- pressed by the more convenient symbols. The principal difficulty is the formation of the geni- tive case. The following rules (Mann) will as- sist in overcoming the difficulty. They apply only to pharmacopceial nouns. RULES FOR rORMATIOX OF GENITIVE CASE. I. . All nouns ending in a form the genitive in GP as quinina, quininas. Exception. — Physostig- ma, Physostigmatis. Coca is unchanged. Folia is plural, Genitive Foliorum. II. All nouns ending in us, um, os, on, form the. genitive in i as Conium, Conii. Exceptions — Rhus. gen. Rhois, Flos, gen. Floris, Erigeron, gen. Erigerontis, Fructus, Cornus, Quercus^ Spiritus, do not change. III. All other nouns of whatever termination make the genitive in .9. or is, chloral, gen. chlor- al is. Some lengthen the termination thus: as genitive atis as Acetas, Acetatis. is " idis as ^nthemis, Anthemidis. '■ onis as Pepo, Peponis. X " CIS as Cortex, Corticis. There are a few exceptions. Asclepias, gen. Asclepiadis : Mas. gen. Maris: Phosphis, 8ul- phis. etc. gen. itis : Mucilago. gen. Mucilaginis ; Solidago. gen. Solidaginis, etc. The following words do not change in their genitive.^ Amyl. Azedarach. Berberis, Buchu, Cajuputi. Cannabis, Catechu. Condurango, Cor- * Those in italics are indeclinable, those in us are of the fourth declension; the others are of the third. Apiol and Sumbul are given as indeclinable by some authorities, Dunglison gives Apiolum, i; Sumbul, i; Amyl, Amylis is also given. 75 nus, Curare, Fructus, Digitalis, Hydrastis, Ja- borandi. Kino. Matico, Quercus, Sassaf7-as, Sago, Sinapis. Spiritus. It is seldom necessary to use the accusative of the nouns expressing the ingredients, only when the quantity is omitted, and a numeral ad- jective takes its place. As before stated, the use of the appropriate symbols renders it unnecessary, as a rule, to write out in the accusative the words express- ing quantity. Sometimes, however, it is desir- able to do so, and the following simple rules for the formation of the accusative of these words are appended: I. Nouns expressing quantity ending in a, are feminine and make the accusative singular in am and the plural in as. Example, Drachma, ace. sing. Drachmam, pi. Drachmas. II. Those ending in um or us make the accu- sative singular in U7n. The accusative plural of those in ns is os. and of those in um is a. Those in us are masculine, those in um are neuter. Congius. ace. sing. Congium, ace. pi. Congios. Granun), '" " Granum, ace. " Grana. The adjectives are declined like the nouns. The numeral cardinal adjectives are indeclin- able except unus, duo and tres. They are thus declined. Masculine. Feminine. Neuter. Nom. unus, una, unum. Gen. unius, uniuc, unius. Ace. unum, unam, u:ium. 76 Masculine. Feminine. Neuter, duo. duorum. duo. tria. trium. tria. The following is a list of some of the more frequently used numeral adjectives: CARDINALS ORDINALS Nom, duo. duae, Gen. duorum, duarum, Ace. duos. duas^ Nom. tres, tres, Gen. 1 rium, trium, Ace. tres, tres, 2 3 4 5 6 7 8 9 lo II 12 13 H 15 i6 17 i8 19 20 21 22 30 40 50 60 .70 80 90 100 I II III IV V VI VII VIII IX X XI XII XIII XIV XV XVI XVII XVIII XIX XX XXI XXII XXX XL L LX LXX I^XXX xc c Unus Duo Tres Quatuor Quinque Sex Septem Octo Noveni Decern Undecim Duodecim Tredecim Quatuordecim Quindecitii Sexdecim Septendeeini Octodecim Noveudecim Vigenti Vigenti unuir Vigenti duo Trigiuta Quadraginta Quinqnaginta Sexaginta Septuaginta Octagiuta Nonaginta Centum X St 2nd 3rd 4th 5th 6th 7th bth 9th loth nth 1 2th 13th 14th 15th 16th 17th i8th 19th 20th 2ISt 22ud 30th 40th 50th 60th 70th 80th 90th looth Primus Secundus Tertius Quartus Ouintus Sextus Septimus Octavus Nonus Decimus Undecimus Duodecimus Tertius decimus Quartus decimus Quintus decimus Sextus decimus Septimus decimus Octavus decimus Nonus decimus Vicesimus Vicesimus primus Vicesimus secundus Tricesimus Ouadragesimus Quinquagesimus Sexagesimus Septuagesimus Octogesimus Nonagesimus Centesimus 77 The verbs are nearly all used in the impera- tive mood; being addressed to the compounder. The following are some of the more common ex- amples: Recipe, take; Misce, mix; ^igna, mark; Divide, divide; Mitte, send; Pone, put; Extende, spread. A few verbs are, however, in the subjunctive mood of mild command, taking the subject re- ferred to in the nominative case, e.g., fiat, plu- ral fiant, let be made. Detur, plural demur, let be given. Sufflciat, may suffice. Repetatur, let it be repeated. Only a few prepositions are commonly used; they are ad, to; ana (Greek), abbrev. a a, of each; cum, with; in, into; ad and in govern the accusative, cum. the ablative and ana the geni- tive cases. The following phrases are used: Fiat lotio. Let a lotion be made. Dividatur in partes oequales. Let it be divided into equal parts. Dentiir tales doses. Let such doses be given. Quantum sufflciat. abbrev. q. s., as much as may suffice. Ne repetatur. Do not repeat. The following abbreviated prescription may be used, when written out in full and rendered into Latin, to illustrate many of the points al- ready referred to: R Powd. Scammony, Q ss Jalap, gr v Calomel, gr M, Fiat pulvis purgans. The prescription is taken from Pereira and Griffiths and when put into Latin would appear and be explained as follows: 78 .5 -^ Q < -t: -^ > w < ^ •^ ^ ^ S ^ OJ 3 ^ 3 ^ > " 3 C C/^ O' ?% '^ ?..-^ ■C^ y 3 .^ en en -*-> c „ be S a^ o OJ c - =^ ^ ■" tn ti CD 'J} '5 .ti ^ ^ ^ O rO S: o o -c<, m .^ ^ ^ ^ ti M -c ^ p o Pi 1) a, 5 "2 <^i 13 % bJD o ^ o il ,_^ ^ 5 « cT (U pij 03 -e O O S N •i Pi p. ^ H 1) ^ cc 3 ^ t > CD S O 'T3 5 3^.

It is irrational to combine a number of agents (shot gun prescription) without especial attention to the specific action of each. In constructing a prescription, it is first neces- sary to decide upon the proper remedial agents; then upon the size of the aose and lastly the number of doses to be given. The prescription on p. 72 written out to show these details would be as follows: R ^ Nucis Vomicae, (single dose "^j X6^) ^vj Ferri Sulphatis, ( " " -^j X6^) "^vj Aloes Barb., ( " " "^ss X6=) "^iij Syrupi Zingiberis, q. s. Mix and make into six balls. In practice the multiplication of single doses Is carried out mentally and the product only is written down. The Roman numerals should always be used to designate the quantities; thus: i, ij, iij, iv, V, vj, vij, viij, ix, etc. Always dot each i to avoid mistakes; the last i is usually made in the form of a j to show that it is the last of a series. AN EASY METHOD OF WRITING PRESCRIPTIONS IN THE METRIC SYSTEM (AFTER LEONARD). In a two ounce prescription a single dose, in grains or minims, is given in the same figures as 81 the total amount of the drug in the prescription expressed in grams or cubic centimeters, as for example: ^ Pluidextracti Belladonnse Radicis (2 minims dose) = 2 cc. Potassi Bromidi (8 grains dose) = 8 grams Aquae q. s. 2 fluid ounces = 60 cc. In a two ounce prescription there would be fifteen doses. In a gram or 1 cc, there are ap- proximately 15 grains 'or minims; the basis is therefore 15 to 1. In a one ounce mixture there would be one half the above amounts; in a four ounce prescription there would be twice the above amounts. Or the same amounts of the drugs may be used in a four, six or eight ounce mixture as for the two ounce mixture and the dose correspondingly doubled, trebled or quad- rupled. COLEMAX'S EASY METHOD OE' WRITING PRESCRIPTIONS. "It may be assumed for the purpose of writ- ing prescriptions, that there are fifteen doses of a teaspoonful each in a 2 ounce mixture; 30 in a 4 ounce mixture; 60 in an 8 ounce mixture. Only in the case of dangerous drugs is a more accurate estimation necessary. In a 4 ounce mixture, then, with a teaspoonful dose, each dose will contain 1-30 of the total amount of any drug which may be in solution or uniform suspension. In the case of drugs with a usual dose of about 5 gr. or m., 1 dram may be taken as the basis of calculation. If 1 dram of a drug be added to a four ounce mixture, each teaspoonful will contain 1-30 of a dram, or 2 grains or minims. Taking 2, then, as a unit, it is only necessary to find the multiple of 2 which will give the de- sired dose and mis will represent the number of drams to be put into the prescription. To take an example, Tincturae Opii Camphoratse, (dose 15 m.) Salol, (dose 5 gr. ) 2x24 ='^ ij ss Mistura? Cj eti«, q. s. ad o "^ M. et Sig. In a 2 ounce mixture, each teaspoonful will contain 1-15 of a dram, or 4 gr. or m. In an 8 ounce mixture, each teaspoonful will contain 1-60 of a gr. or m. From the above statements the following rule may be formulated: Divide 60 (one dram) by the number of doses in the prescription and multiply the result by the numeral necessary to give the desired dose. This numeral will represent the number of drams to be used. In the case of drugs with a maximum dose of less than a grain, 1 grain instead of 1 dram may be taken as the basis of calculation. Thus, if one grain be added to a 4 ounce mixture with a teaspoonful dose, each dose will contain 1-30 of a grain." The above methods are applicable especially- in human and canine practice. 83 leoxard's quick way of reducing percentages. Rule I. Call the numerator of the fraction one grain. Rule II. Double the first figure of the de- nominator and call this ounces. This will then give almost mathematically correct reductions. Thus: 1 to 1,000 would be 1 grain to 2 ounces; 1 to 2,000 would be one grain to 4 ounces; 1 to 3,000 would be 1 grain to 6 ounces; 1 to 4,000 would be 1 grain to 8 ounces; 1 to 5,000 would be 1 grain to 10 ounces and so on. If you want 1 to 500, this would be 1 grain to 1 ounce — there being 480 (approximately 500) grains or minims to the ounce. One to 100 would be 5 grains to 1 ounce. By committing these two simple rules to memory, an instantaneous reduction for any percentage mixture can be made to the apothe- cary's basis." WEIGHTS AND MEASURES. Those most generally used by the physicians and pharmacists in the United States are the Troy or Apothecaries' Weights, and the Wine or Apothecaries' Measures. The Metric System, however, has been recognized to such a great extent that it has become a necessity for physi- cians to become familiar with it. TROY OR APOTHECARIES' WEIGHTS.

Pound Ounce Grain {Libra) { Uncia ) {Granu7n) lb. I =: 16 = 7000 oz. r = gr. 437>^ To avoid misapprehension in the use of the apothecary and avoirdupois systems, the sym- bols lb., ^^^ ^^ 5^ should be consistently used for the apothecary and the abbreviation lb., oz., gr., for the avoirdupois. The abbreviation for the Troy pound is characterized by the cross line drawn through the letters lb and should always mean twelve ounces, while the avoirdu- pois pound (lb.) stands for sixteen ounces. The symbol ^ means an apotnecaries' ounce of 480 grains, while "oz." means an avoirdupois ounce of 4371/^ grains. The grain weight is the same for both systems and the abbreviation gr. will cause no confusion. The grain is therefore the unit in both systems and the term is derived from the old system of weighing, which re- quired that there should be used a "grain of wheat, well dried and gathered out of the mid- dle of the ear." The abbreviation gr., for grain, should be consistently used in the apothecary system, gm. for gram, in the metric system. 85 In using the metric system of weights the gram is ordinarily used as the standard and the other subdivisions are reckoned from it. METRIC WEIGHTS. 10 milligrams (mg.) make 1 centigram (eg.) 10 centigrams make 1 decigram (dg.) 10 decigrams make 1 gram (gm.) 1000 grams make 1 kilogram (kilo.) METRIC MEASURES. 1000 Cubic centimeters (cc.) (Milliliters) make 1 liter (L.) 1 Gram equals the weight of 1 cc. of distilled water at a temperature of 4°C. TABLE OF APPROXIMATELY EQUIVALENT WEIGHTS. 1 milligram .001 = 1-64 grain 1 centigram .01 = 1-6 grain 1 decigram .1 = 11/^ grains 1 gram =151/^ grains 4 grams ( 3.9 gm.) = 1 dram 30 grams ( 31.1 gm.) = 1 ounce 500 grams (453.6 gm.) = 1 pound (av.) 1 kilogram =2 1-5 pounds (av.) 1-64 grain = 1 milligram = .001 gram 1-6 grain = 1 centigram = .01 gram 1 grain = .065 gram 15.43 grains = 1. gram 1 dram (apoth.) = 3.90 grams 1 ounce (apoth.) =31.1 grams 1 minim = .061 cc. 16 minims = 1. cc. 1 fluidram = 3.75 cc. 1 fluidounce =30. cc. 86 1 cc. =16 minims 4 cc. (3.7 cc.) = 1 fluidram 30 cc. = 1 fluidounce • To convert grains into centigrams, multiply- by 6.5. Thus 3 grains multiplied by 6.5 equals 19.5 centigrams, or 10 grains equals 65 centi- grams or .65 gram. To convert centigrams into grains divide by 6.5. Thus 26 centigrams di- vided by 6.5 equals 4 grains. DOMESTIC MEASURES, A drop, gutta, (gtt.) is usually reckoned at about one minim. A tea-spoonful is about one fluidram. A table-spoonful is about one-half fluidounce. A wine-glassful is about two fluidounces. A tea-cupful is about five fluidounces. A breakfast-cupful is about eight fluidounces. A tumblerful is about eight fluidounces. Domestic measures vary considerably. There may be from 50 to 150 drops in a fluidram, a tea- spoon generally holds more than one dram, even as much as 2 drams or more. Cups and glasses also vary widely. THE PRINCIPLES OF COMBINING DRUGS IN A PRESCRIPTION. Although the tendency in modern therapeutics is toward simplicity rather than complexity in prescriptiolis, one may go to the extreme even in this direction. There is no doubt but that in very many cases a judicious combination of drugs will produce effects of a beneficial charac- ter which might be sought in vain from the use of a single remedy. A "shot gun" prescription. 87 containing a great number of remedies intro- duced with the idea that by some lucky chance one or more of the ingredients may hit the dis- order, is thoroughly unscientific and not to be encouraged. The rational combination of drugs was, per- haps first discussed fully by Dr. John Ayrton Paris (Paris Pharmacologia, 1822). His treat- ment of the question has been so clear and ex- haustive, that there has been but little room for improvement. The following paragraphs are based principally upon his work: I. The Action of a Medicine May be Aug- mented (Adjuvant Action). (a) By comMning different forms of the same substance. An infusion is strengthened by the addition of the fluid extract or tincture of the same drug, in cases where all the active prin- ciples are not soluble in the same vehicle. Digi- talis may be taken as an example, all of its ac- tive principles are not soluble in water. (b) By comhitiing the medicine loith others ivhich produce similar effects. A rule enunci- ated by Dr. Fordyce is to the effect that com- bination of similar remedies will produce a more certain, speedy, and considerable effect than an equivalent dose of any single one. A combination of chloral and bromide potassium is more certain for hypnotic effects than either one alone. From the standpoint of purgation the same would be true of a combination of aloes and calomel, or as an emetic a mixture of i])ecac and tartar emetic is more reliable for its effects than either drug singly. (c) By comMning with the basis substances of a different nature which can, in some un- knoion manner enhance its action. The diuretic effect of squill is increased by calomel, and ipecac assists in the purgative action of jalap. II. The Action of a Medicine May be Modi- fied ( Corrective Action ) in Order to Overcome Unpleasant Effects. The griping tendency of purgatives may be corrected by combination with aromatics or essential oils. Acrid sub- stances may be more or less overcome by tri- turating with mucilage. The constipating effect of iron may be overcome by the addition of aloes. See prescription p. 72. III. To Obtain the Combined or Joint Ac- tion OF Two OR More Medicines. (a) Upon the same tissue. Purgative medi- cines will serve as an illustration. Some act by increasing peristalsis, others by augmenting the secretion of the. intestines, as in the case of eserine and pilocarpine. The combination of podophyllum with calomel, for their joint action upon the liver, may be cited as another ex- ample. (b) Upofi different tissues or to combat dif- ferent symptoms. Probably the greatest num- ber of prescriptions will come under this head. The desire to combat a number of different symptoms should not lead to excess in the com- bination of drags. A well directed rifle ball will have a greater effect than a charge from a shot gun where only a few of the shot hit the mark. Some prescriptions have been reported which contained as many as 400 ingredients. 89 The more complicated a prescription, the great- er are the chances for failure. The symptoms of fever with cough may be treated with small doses of ipecac as a sedative expectorant, tincture of aconite to quiet the cir- culation and allay the fever, with potassium bromide to alleviate excessive coughing. Other cases will readily suggest themselves. It may be desirable, in a given instance to stimulate the heart with one drug and the kidney or bow- els with others. IV. To Form New Compounds the Effects OF Which Differ from any of the Individual Constituents. Dover's Powder is a good illus- tration. This preparation has marked diaphor- etic properties, while neither of its constituents, opium or ipecac, when taken separately exert any powerful action upon the skin. "White Lotion" made by dissolving lead acetate and zinc sulphate in water; "Black Lotion" by add- ing calomel to a solution of lime and "Yellow Lotion" by adding corrosive sublimate to a solu- tion of lime, are also examples. V. To Afford a Convenient and Agreeable Form of Administration. Solids, such as pills, capsules and powders are oftentimes to be pre- ferred. Liquid preparations are sometimes more desirable and they have the advantage of being more readily absorbed. The main thing, of course, is that the patient should get the proper remedy indicated by the symptoms; but, at the same time, it is the duty of the prescriber to see that it is no more obnoxious than need be. This fact is sometimes lost sight of in vet- 90 erinary practice, where the animal may be com- pelled to take the medicine, but nothing is lost to the patient or prescriber, if the medicine is prepared in as palatable a form as possible without sacrificing anything of its pharma- cologic action. Due care should be exercised in selecting a vehicle which has little or no medicinal action of its own, or if it has that it will assist or cor- rect the action of the medicines prescribed, and, if practicable, one in which the other in- gredients are soluble. The taste of many bitter substances like qui- nine, and salty drugs like ammonium chloride, may be made more agreeable by the addition of any of the preparations of glycyrrhiza. Caustic or irritating medicines, whether liquid or solid, must be well diluted before being swallowed. EXAMPLES OP PRESCRIPTIONS. The following graded scheme for the begin- ner in prescription writing may be employed; 1st, a prescription written out in Latin is trans- lated into English with the quantities of the ingredients expressed in both the apothecaries and metric systems. 2d. An abbreviated pre- scription is written out in English, apothe- caries and metric. 3d. An abbreviated prescrip- tion is written out in Latin; apothecaries and metric. 4th. After a student has studied thera- peutics a card is given aim bearing the name of a disease, with the basis or principal remedy indicated from which he is to construct a com- pound prescription suitable for the disease mentioned. 91 The following prescriptions are given as illus- trations of the scheme and serve merely as an outline of the way in which the work may be carried on. The instructor can prepare any number of prescriptions under each grade for the student's exercises. The various symbols, unusual endings and combinations may be included in such prescrip- tions for purposes of instruction. LATIN INTO ENLISH.

In prescription writing, incompatibility may be defined as an interference, with each other, of the constituents of a mixture in a way not intended by the prescribe'r. Sometimes there is intentional incompatibility by the preseriber as in the case of white lotion, p. 89. There are three types of incompatibility: Chemic, Pharmaceutic and Physiologic. Cliemic IncompatiMlity occurs when a new chemic compound results. In general it may be recognized in one of three ways: 1. By precip- itation — the formation of an insoluble com- pound. 2. By effervescence or explosion — evo- lution of gas. 3. By a change in color. An- other form may be referred to, because it is not easy to recognize any change and therefore more dangerous. A new product may be formed, possibly of a poisonous nature and remain in solution without in the least chang- ing the appearance of the mixture. The avoid- ance of this form of incompatibility rests upon a knowledge of the ordinary chemic reactions, and the knowledge cannot be too greatly em- phasized. Chemic incompatibility is not always evident immediately, some little time may elapse before changes occur. A general rule is that substances are incompatible if they are used in testing for each other or if they form antidotes. Pharmaceutic Incompatibility results in the production of an unsightly appearance due to physical changes. It is, therefore, largely a question of solvents and solubility, and often Ill occurs when solids or liquids are added to solu- tions, thereby changing their densities. It occurs when there is a combination of such sub- stances as are physically incapable of mixing; thus, if spirit of nitrous ether be added to tincture of guaicum a gelatinous mass will re- sult, or if resinous tinctures be added to -aqueous solutions the resins will separate. Physiologic or Therapeutic Incompatibility depends upon the antagonistic or opposite physiologic or therapeutic actions of the drugs, so that one drug may weaken or neutralize the action of another with regard to its effects upon the tissues. Atropine and pilocarpine are ex- amples of antagonists therapeutically. No two drugs, however, are exactly opposed to each other throughout their whole range of action, and more or less latitude in this respect may be permitted in prescribing. Incompatibility must always be kept in mind in writing a prescription. It is best avoided, as a rule, by not attempting, to combine too many drugs. Some general principles which it is well to keep in mind may be formulated as follows: Acids should not be added to alkalies, alka- line salts or vegetable acids on account of de- composition and chemic change. Solutions of alkaloids are incompatible with tannic acid, alkalies, alkaline salts, iodides and bromides on account of precipitation. Glucosides (Digitalin, Salicin, etc.) are de- composed by acids. A mixture of salts in solution will decom- 112 pose if either an insoluble compound or double salt can be formed. Chloral is incompatible with alkaline solu- tions, chloroform is produced. Potassium chlorate, nitrate or permanganate liberate oxygen and should not be mixed with readily oxidizable substances, such as charcoal, sugar, sulphur, glycerin, carbolic acid, iodine, turpentine, and organic materials, lest explosive compounds be formed. Lime water precipitates mercury salts. Calo- mel and prussic acid form the poisonous mer- curic cyanide. Calomel should not be combined with nitro- hydrochloric acid as corrosive sublimate may be produced. Both calomel and antipyrin are incompatible with sweet spirit of nitre. Liquid iron preparations are incom'patible with fluid preparations of the vegetable bitters (except calumba and quassia), because the tannic acid in them forms a precipitate. Considerable quantities of acid are incom- patible with tinctures, because ethers are formed. Water causes precipitates with tinctures con- taining resins. Gum arable is incompatible with lead and iron salts and mineral acids. Solutions of potassium chlorate and iodide unite to form a poisonous compound.

EXAMPLES OF INCOMPATIBILITY IN PRESCRIPTIONS * Sodii Boratis, gr x Zinci Sulphatis, o-v Aquae Camphorae, f-~ Aquae Rosae, qs. ad., f^ M. Sig. Put one drop in each eye night and morning. The zinc is entirely precipitated by the borax, producing a white fiocculent precipitate of zinc borate or hydrate. If dispensed, the precipitate should be filtered out. Iodine, gr xxx Spirit of Camphor, f ~~ Soap Liniment, f^^TT Mix and label. Apply as directed. This makes a clear brownish-red solution, w-.xii on standing two or three days loses much of its color, becoming light brown. On applying the starch test for free iodine no blue color was obtained. According to Muir and Morley, iodine with camphor forms a hydrocarbon and other substances.

There is considerable danger of having an explosion in attempting to hll this. If the potas- sium chlorate is rubbed with the glycerin, ex- plosion is liable to take place or if the chlorate be added to the solution of ferric chloride, which always contains some free hydrochloric acid, chlorine will be formed, and this will act upon the glycerin, converting it into oxalic and carbonic acids. In filling this the temperature should not go above 70°F., and then the bottle should be loosely stop])ered for a time before giving out. Iodoform, Tannic acid, aa -i^^^ Mix and label. Dust over abraided surface. No change is noticed in the appearance of this mixture on standing. The odor of the iodoform slowly diminishes, and, according to the U. S. Dispensatory (17th Ed.), this is due to the de- composition of the iodoform by the tannic acid. Sodii Salicylatis, oTT^s Syrupi Limonis, f,ln~ M. Sig. Teaspoonful three times a day. On standing, the citric acid in the. syrup com- bines with the sodium, liberating salicylic acid, which, being only sparingly soluble in water, is precipitated in needle-shaped crystals. This can be dispensed as a shake mixture. The precipi- 138 tation is rather tardy and it would be well to give notice of the change which will take place. Liquoris Potass.

Fowler's solution is alkaline, due to the excess of potassium bicarbonate used in making the solution. Boiling with water con- verts the bicarbonate into the normal carbonate of potassium to some extent. Either the bicar- bonate or the normal carbonate precipitates mercuric chloride in solution as the red-brown mercuric oxychloride. If the solution of arsen- ous acid be used, instead of Fowler's solution it will not give a precipitate with corrosive sublimate. ft Quininae Sulph., gr x Potassi Acetatis, gr xx Acidi Sulphuric!

On dissolving the quinine sulphate in part of the cinnamon water with the aid of the sul- 139 pliuric acid, then adding the potassium acetate previously dissolved in the remainder of the water, a voluminous precipitate of quinine ace- tate is obtained. Quinine acetate is only spar- ingly soluble in water, and the amount here formed is so large and bulky that it is difficult to pour out an even dose. It Acidi Carbolici, ri^^ Aquae, q. s. ad, ■^ M. S. Use with camel-hair brush. Water can be added to carbolic acid, until the proportion is about 3 parts of acid to 1 part of water, forming a clear solution. (Allen). On adding more water the acid separates as an oily liquid, going to the bottom. When water has been added so that the proportion is about 1 part of acid to 15 parts of water, a clear solu- tion again results. In this prescription there will be a layer of liquefied acid in the bottom of the bottle. If the brush should remain in the bottle between the periods of using it there is danger that it will become saturated with the strong acid and that it will be applied in this condition. By the use of some glycerin in place of part of the water a clear solution can be made and this is what should be done. It Syrupi Acidi Hydriodici, f.lri" Bismuthi Subnit, 5" ISS 140 M. S. Teaspoonful three times a day. The bismuth subnitrate is. insoluble in the syrup, but a chemical reaction takes place be- tween it and the hydrioaic acid, as is evidenced by the change in color. Bismuth subnitrate is white; on mixing it with the syrup the color becomes yellow, and within a few minutes it turns to a dark brown and then grayish black. On allowing the precipitate to settle it appears to be a mixture of two compounds, one yellow and the other dark gray. According to Watts' Dictionary, the oxyiodide of bismuth is copper- colored and the bismuth iodide is a brilliant gray. Alcohol. 30 cc. Iodine, 10 gm. Turpentine, 200 cc. Mix. To be used as a spray. If the turpentine is poured upon the iodine violent chemical reaction results, with the for- mation of violet fumes of vaporized iodine, caused by the heat generated. While there is not enough of alcohol to dissolve all of the iodine, it is best to dissolve as much as pos- sible before adding the turpentine, which should be added in small portions, cooling the mixture if necessary. Upon standing the liquid sepa- rates into two layers. The lower one, being much smaller in amount and very dark colored, is probably the alcohol holding most of the 141 iodine in solution; the upper stratum is very- much lighter in color and is probably the tur- pentine. Turpentine and alcohol are not miscl- ble in all proportions. Bismuth Subnit., •^~Y~ Sodii Bicarbonatis, grxxx M. Fiant pil., No. XX. In mixing these two substances chemical re- action takes place, with the liberation of carbon dioxide, which causes the mass to swell to sev- eral times its original size. This reaction goes on slowly requiring several hours for its com- pletion, and the mass should not be made into pills until the reaction has been completed. If the subcarbonate had been substituted for the subnitrate incompatibility would have been avoided and the same physiologic effects ob- tained. a^ Potassii Bromidi, grxv Hydrargyri Chlor. Mitis, grxv Misce et fiat pulvis: Mitte tales No. XII. If the ingredients are powdered separately and are perfectly dry when mixed no chemical reaction takes place. But upon addition or wa- ter or in the presence of moisture the powder becomes dark gray in color. The darkening is due to the formation of metallic mercury. At 142 the same time some of the calomel is converted into a mercuric salt, rendering the prescription dangerous. It should not be dispensed. Morphinae Sulph., gru Sp.

This is a very common combination. Lead subacetate forms compounds with nearly all alkaloids, and these are insoluble in water. The opium alkaloids are no exceptions. The alcohol of the tincture undoubtedly tends to prevent the precipitation to some extent, though there is still quite a heavy one. The mixture should not be filtered. 143 Cocainae Hydrochlor., grv Sodae Boratis, sr " 6 IJ Aquae Dest., 5 '. M. S. Drop one drop in right eye at night. Borax is alkaline in reaction and precipitates nearly all alkaloids from solutions of their salts. It precipitates the cocaine in this pre- scription, but the difficulty can be prevented by the use of a little glycerin. The glycerin acts chemically on the borax, breaking it up and forming sodium metaborate and boric acid. If boric acid were used instead of borax no pre- cipitation would occur. Sp. Ammoniae Arom., f^^'^ Liquoris Calcis, fSnss M. S. Dessertspoonful as needed. On mixing these two ingredients together a white precipitate of calcium carbonate is formed, the spirit containing ammonium car- bonate. The lime water also throws out of so- lution the oils of the aromatic spirit. Whether the precipitate should be filtered out or not must depend upon the conditions for which the medicine is prescribed. 144. POISONS AND IHEIR ANTIDOTES * In treating cases of poisoning, four indica- tions must be kept in mind: (A) How to most quickly get the bulk of the poison out of the stomach by forcibly emptying it; (B) how to antidote the residual poison after evacuating the stomach; (C) how to eliminate from the system the poison that has entered the blood or gone on into the intestines; (D) how to treat the dangerous symptoms as they arise from the effects of the poison. AcETANiLiD. Antifebrin, Antipyrin. — Place patient in a recumbent position, allow plenty of fresh air; give stimulants (brandy, whiskey, aromatic spirits of ammonia, etc.) Apply heat externally; use atropine or belladonna to main- tain blood pressure; strychnine to aid respira- tion; oxygen inhalations if there is excessive cyanosis. Acid Acetic. — Administer magnesia freely; soap and water; lime water; chalk; milk, oils and thick gruel may be given. Acid Carbolic — Unless great destruction of mucous membrane has occurred, produce vomit- ing by means of warm water containing some sodium bicarbonate or zinc sulphate; mustard; apomorphine. Demulcent drinks, flaxseed or elm tea, and white of egg beaten up with water, protect mucous surfaces. Do not give oils or glycerin. As stimulants use whiskey, alcohol, ammonia, etc., hypodermically if need be, *From Merck's Report Read}' Reference. (Adapted to veterinary practice. When vomiting is mentioned it is understood to refer to the smaller animals as the pig, dog and cat; not to the herbivora). 145 warmth; friction. Opium relieves pain. Excite counter irritation over the abdomen. Give digi- talis and strychnine if needed. Recently whis- key and brandy have been warmly recom- mended, followed in a few minutes by a hypo- dermic injection of apomorphine to produce vomiting. A Dublin veterinarian, Allen, has lately recommended turpentine for carbolic acid poisoning. Acid, Carbonic and Coal Gas. — Bring the patient at once into the open air. If the respira- tory movements have ceased, cold water should be dashed on the face and chest, to awaken them to reflex action. If no effect is thereby produced resort to artificial respiration which should be continued for at least an hour. A series of quick sharp blows over the - cardiac region will sometimes start the heart into ac- tion after it has stopped. Inhalation of oxygen or ammonia vapor, or an enema of black coffee, and venesection, may be of service. Acid, Chromic, Potassium Chromate and Bichromate. — Evacuate the stomach with i/^ oz. of mustard stirred to a cream with 1 oz. of water; (man or dog), or with zinc sulphate, apomorphine; ipecac or pump. Follow with magnesium oxide or carbonate, sodium bicar- bonate, or chalk, in water; as demulcent drinks give barley, elm or flaxseed water. Acid, Hydrocyanic, Cyanides, Cherry-Laurel Water, Oil Bitter Almond. — Fifteen minims of official acid, or 1 grain of anhydrous acid, usu- ally kills (man or dog) in 10 to 15 minutes. Place in recumbent position, allow plenty of 146 fresh air; empty the stomach by mustard, zinc sulphate, or pump; keep the body warm. If breathing ceases, use artificial respiration, mild faradic current to the heart, alternate cold and warm affusion to head chest and spine; admin- ister ammonia by inhalation or give it by mouth or veins; inject atropine solution 2 to 4 drops every half hour, to assist the heart's ac- tion. Ferrous sulphate with ferric sulphate, followed by potassium carbonate, yields inert Prussian blue. Ferrous sulphate alone or with calcined magnesia renders the acid insoluble, but the action of the acid is so quick that there is scarcely time for the applications of many remedies. Brandy by the mouth, skin, or rec- tum has been found valuable. Acin, Oxalic and Oxalates. — Half to one ounce usually proves fatal (man or dog). If not already vomited by the poison, empty the stom- ach at once with mustard, zinc sulphate, pump or tube, then neutralize with chalk, whiting, or wall plaster in water, or lime water itself, never with sodium, potassium or ammonia salts, as these form soluble oxalates; apply hot fomenta- tions to the loins. Give an enema to empty the bowels. Give much water to facilitate elimina- tion by the kidneys. Acids, Mineral: Hydrochloric, Nitric, Nitro- hydrochloric, sulphuric, phosphoric ouc to four drams of the stronger acids usually proves fatal (man and dog). Neutralize with sodium bicarbonate, calcined magnesia, lime, chalk, or wall plaster mixed with water; if none of these are accessible, dilute and wash out the stomach 147 with considerable water. One may use with ad- vantage any of the following — soap, milk, gruel, olive and almond oil, eggs beaten up. Avoid the stomach pump as it might perforate the soft- ened oesophagus. Aconite and Aconitine. — Thirty to sixty drops of tincture or one-twentieth grain of alka- loid generally prove fatal (man or dog). Evacu- ate the stomach at once with zinc sulphate,' apomorphine, mustard, or pump; place in a recumbent position, the head the lowest; apply warmth to the extremities; give solution, four drops hypodermically or, give tincture of bella- donna twenty drops by the mouth, repeated. If heart syncope presents, give tincture of digitalis fifteen drops hypodermically or thirty drops by the mouth. As stimulants, use ammonia, brandy, strychnine, mustard plasters to the chest. Aid vomiting and elimination of the poison by abundant water, to which may be added brandy or alcohol in any form. Inhale amyl nitrite, or oxygen, and if breathing stops use artificial res- piration. Animal charcoal and tannin are of service. (The doses of the antidotes mentioned above are for man and dog; for larger animals the dosage should be in proportion to size). Alcohol. — Inebriation somewhat resembles opium poisoning and concussion of the brain. Empty the stomach, wash out well with warm coffee, keep the body very warm, but apply cold douche to the head; allow plenty of fresh air; apply interrupted current to the respiratory muscles; ammonia water or amyl nitrite to the 148 nostrils; keep the patient awake mechanically by shaking, shouting, etc. Alkalies, Potassa, Soda and Ammonia. — They usually cause vomiting, but if they do not, accomplish this by plenty of luke-warm water, to be followed by vinegar (dilute acetic acid, lemon or orange juice, tartaric or citric acid solution, 2 drams to a pint of water) ; olive oil (1 to 4 drams for man and dog) ; egg white, milk, demulcent drinks (arrowroot, elm, bar- ley, or flaxseed water) to protect the mucous membranes and "sustain vital powers. May al- ways give plenty of water and relieve pain with laudanum or hypodermics of morphine. Alkaloids in General. — Tannin generally forms comparatively insoluble tannates: albu- min; iodine and charcoal also of service; use emetics and cathartics later. Ammonia. — Administer vinegar, lemon juice, orange juice, or any vegetable acid, followed by demulcents to protect the mucous surfaces. When inhaled, give vapor of acetic or hydro- chloric acid or chlorine water by inhalation. Amyl Nitrite. — Atropine, ergotin, or strych- nine hypodermically are the best antidotes; stimulants, alternate hot and cold douches, with cold to the head, and artificial respiration are also useful measures. Antimony Compounds, Tartar Emetic. — In man, 2 to 5 grains have occasioned death, while several drams have failed to produce more than great vomiting and alarming general symptoms. Should these fail to cause the patient to vomit one must create this by mustard, zinc sulphate. 149 apomorphine or pump; follow with strong tea or coffee, solution of tannic or gallic acid, to form an insoluble compound. Give demulcent drinks (flaxseed, slippery elm, egg white, milk) ; opium and rtimulants in small but fre- quent doses. If the body be cold, apply blan- kets; faradic current over the heart if neces- sary. Instead of tannin, freshly precipitated ferric hydroxide can be used, following with opium or morphine for the pain. Antipyrin. — See Acetanilid. Apocynin. — Like Digitalis. Arsenic Compounds. — Unless the poison itself vomits, accomplish this with mustard, zinc sul- phate, apomorphine, pump, or tube. Either wash out the stomach with a large quantity of water or give freshly precipitated hydrated oxide of iron, made by double decomposition be- tween any ferric solution and a solution of either diluted ammonia water, sodium carbon- ate, or magnesium oxide, the object being to form insoluble ferric arsenite or arsenate. The ammonia acts as a stimulant, the calcined mag- nesia as an aperient. One may give with ad- vantage, oil, mucilaginous drinks, egg white, and in case of faintness, stimulants. If the skin be cold, apply hot blankets, and relieve the pain by opium or morphine; one may conclude with a dose of castor oil. Atropine. — See Belladonna. Barium Compounds. — See Lead compounds. Belladonna or Atropine, Hyoscyamus ob Hyoscyamine, Stramonium or Daturine. Dul- camara or SOLANlNi:. DUBOISIA OR DUBOISINE.— Empty the stomach by mustard, zinc sulphatei 150 apomorphine, pump or tube; give strong infu- sion of coffee, or tea by the mouth or rectum; also pilocarpine nitrate; or instead, use mor- phine, opium, or physostigmine to antagonize the nervous disturbances of the poison. Apply hot water to the feet; alternate douches of hot and cold water are useful. Give stimulants (whiskey or brandy), ammonia to the nostrils; also practise artificial respiration. BenZexe. — Evacuate the stomach (mustard, zinc sulphate, apomorphine, ipecac, pump). Give abundant fresh air; hypodermic of atropine, or tincture of belladonna. Apply alternately hot and cold water douches to the chest; practise artificial respiration, and apply a mild inter- rupted current over the heart. Blue Stone. — See copper, under mercury com- pounds. Bromides. — Give strong coffee, caffeine citrate, digitalis; morphine is antagonistic to mental symptoms; ergot and belladonna are sometimes used. Bromine. — Give albumin, starch, gelatin, so- dium or potassium carbonate or bicarbonate. Against the irritant vapor, inhalations of steam and ammonia vapor may be employed. Brucine. — See strychnine. Calabar Bean. — See Physostigma. Camphor. — Empty the stomach (by mustard, zinc sulphate, pump, etc.); give alcohol or brandy in small and frequent doses ( best hypo- dermically) ether inhalations; alternate hot and cold douches; warmth to the extremities by hot blankets, etc. 151 C.vx.NABis IxDicA. — Treat as in opium, but also in the first stages use lemon juice. Cantharides or ' Cantharidin. — In man or dog a half dram of powder or one ounce of the tincture usually proves fatal. Empty the stom- ach (mustard, zinc sulphate, apomorphine, ipecac, pump) ; allay pain with morphine hypo- dermically or tincture of opium (through the mouth or rectum). Give plenty of demulcent drinks (barley, elm, flaxseed tea, gruel or pure water) but no oils or oily emulsion, in which catharidin is very soluble; opium, stimulants, warm baths, cataplasms to the abdomen. Carbon Disulphide. — Quiet the nervous ex- citement with potassium bromide and chloral; support the circulation with stimulants; may vomit with mustard at first; ammonia to nos- trils, warmth to the body, cold douche to the head; artificial respiration. Castor Beans. — In man three seeds in one case, and twenty in another, have caused death in two and five days respectively. As soon as they have been swallowed give an emetic (mus- tard, etc.) ; later give demulcent drinks, opium to quiet violent symptoms which resemble those of cholera. Cat Bites. — See Dog Bites. Cherry-Laurel Water. — See Acid Hydro- cyanic. Chloral. — One-half to one dram may prove fatal (small animals) ; empty the stomach (mustard, zinc sulphate, apomorphine, ipecac, pump). When the stomach is empty introduce coffee by tube (mouth or rectum); keep limbs 152 warm (friction, mustard plasters, water bags). Administer hypodermically, fresli 2% solution of strychnine nitrate every fifteen minutes. Picrotoxin may be substituted for strychnine. Arouse the patient and keep him awake by cof- fee, caffeine, flagellation, shaking, shouting; ap- ply ammonia to the nostrils, cold to the head; amyl nitrite inhalation to stimulate the heart; practise artificial respiration if necessary. Chlorates (and Nitrates — potassium, sodium, etc.) — Empty the stomach (mustard, zinc sul- phate, amorphine). Give plenty of water and mucilaginous drinks to dilute the poison, opium to relieve the pain; amyl nitrite inhalations; avoid stimulants that would increase kidney congestion, keep warm by hot fomentations to the loins. Chloroform or Ether, Nitrous Oxide Gas. — Withdraw the inhalation at once, lower well the head; pull the tongue forward so as to ad- mit plenty of fresh air. Use artificial respira- tion and heat; weak current — one pole at the larynx, the other on the pit of the stomach (not far from the diaphragm). Apply hot and cold douche; inhale amyl nitrite. If the heart has stopped, give several taps over that region, in- hale ammonia, give brandy, atropine, strych- nine. If swallowed evacuate the stomach (mus- tard, zinc sulphate, apomorphine, pump) ; enema of hot coffee, large draughts of water, containing sodium carbonate or bicarbonate, and proceed as if inhaled. Chlorixated Lime. — Administer albumin, mu- cilaginous drinks, oils, milk, or flour and water; 153 avoid acids. Opium and alcohol are used for the vital depression. Chlorine. — Against chlorine preparations in the stomach employ albumin or ammonia water in small quantity and well diluted; emesis with warm water, then white of egg, or milk, flour, or lime water. Ammonia vapor is used against inhaled chlorine. Coal Gas. — Carbon monoxide is the poisonous agent. See also Acid, Carbonic. Cobalt. — See Arsenic. Cocaine. — Resembles closely atropine in its general action as to pulse, pupils, respiration, sweat glands and bowels. Give one of the usual emetics, then tannin. Morphine is probably the best all round antagonist; then in sequence, chloral, chloroform, and ether. Give amyl nitrite to counteract heart depression; alcohol and opium to stimulate the heart; should these fail, use artificial respiration. One may em- ploy ammonia inhalations and caffeine. CoccuLus Indicus. — See Strychnine. Codeine. — See Opium. CoLCHicuM (wine or tincture; Colocynth, Elaterium). — If vomiting and purging have not occurred, accomplish the former by one of the usual emetics (mustard, zinc sulphate, ipecac, apomorphine, or pump) ; follow with tannic or gallic acid, or strong tea or coffee; plenty of water and demulcent drinks; opium or mor- phine to allay the pain in the stomach, purging, and to antagonize heart depression, stimulants (alcohol, whiskey, etc.). Keep the extremities warm and apply hot fomentations to the ab- domen. 154 CoLOCYXTH. — See Colchicum. CoNiuM (or Coniine;. — Empty the stomach (mustard, zinc sulphate, apomorphine, pump) ; apply external warmth (hot wraps, bags or bot- tles), give strong tea, coffee, tannic, or gallic acid, or any solution containing tannin; stimu- lants, artificial respiration; strychnine, picro- toxin, active exercise; castor oil. CoNVALLARiA. — See Digitalis. Copper Compounds. — See Mercury Compounds. Corrosive Sublimate. — See Mercury Com- pounds. Creosote. — Practically the same as with Car- bolic Acid. Croton Oil. — Empty the stomach (mustard, zinc sulphate apomorphine, pump) ; give tinc- ture of opium or morphine hypodermically, un- til pain and purging are abated. Give demul- cent drinks (elm, flaxseed water, mucilage, milk, olive oil, albumin, soup) ; spirit of cam- phor in milk; stimuiants (brandy, alcohol, whiskey, ammonia), warm baths are also used. CuRARiXE (or Curare). — If introduced in a wound and all is not removed apply ligature, suck the injured part, washing it out with slightly alkaline solution of potassium per- manganate; apply warmth to the loins, plenty of water internally, artificial respiration; spirit of nitrous ether rapidly eliminates the poison through the urine. The great difficulty is in sustaining life by artificial respiration until elimination begins. Cyanides. — See Acid Hydrocyanic. Oil Bitter Almond. — See Acid Hydrocyanic. 155 Cytisi-xk (or Laburnum Seeds). — Induce vom- iting and wasii out the stomach with strong tea or coffee; follow wim enema or quick purgative; stimulant; rouse the patient by hot and cold douche. Daturink. — See Belladonna. Digitalis (or Digitalin) ; Scillain [Scillitin], (Strophanthus, Strophanthin, Convallaria, Sco- parius). — Evacuate the stomach (mustard, zinc sulphate, apomorphine, pump). Follow with strong tea or coffee or tannic or gallic acid in water. Hypodermic solution of aconitine ni- trate may be given, or tincture of aconite by mouth; if this has given good results repeat in thirty minutes, keep the patient quiet and do not allow an erect position, as that may cause fainting to death. Give stimulants frequently by the mouth, or if vomiting occurs, by the rec- tum. When the drug has been in continuous use, opium is the best antidote. Saponin and Senegin are the best physiologic antagonists. Dog Bites (and Cat Bites). — Suck out the wound well with the mouth, wash with a weak alkaline solution (ammonia, caustic potash, etc.), tnen cauterize with lunar caustic. DuEoisiA (and Duboisine). — See Belladonna. DuLCAMAR.A. (and Solanin.) — See Belladonna. Blaterium. — See Colchicum. Ergot. — Evacuate the stomach (mustard, zinc sulphate, apomorphine, pump). Give pur- gative (Croton Oil) and assist the action by plenty of warm drinks. Tannic or gallic acid may be useful; after vomiting and purging, ad- minister small doses of opium at intervals. 156 Nitroglycerin every 15 minutes has been effect- ive. Allow a recumbent position. Apply warmth and friction to maintain the circula- tion; stimulants; amyl nitrite. EsERiNE. — See Physostigma. Ether. — See Chloroform. Fish Poisox. — Administer emetics and cathar- tics; potassium chlorate; solution ammonium acetate; opium; capsicum or chloroform. Fowler's Solution. — See Arsenic. FuxGi. — See Mushrooms. Gelsemium (and Gelsemine). — Empty the stomach (mustard or pump) ; give atropine hy- podermically or tincture of belladonna by mouih; apply external heat by rubbing; stimu- lants (digitalis, ammonia, coffee, alcohol, arti- ficial respiration, electricity) ; rouse the patient by hot and cold douches. Gloxoin. — Lil^e Amyl Nitrite. Gold Salts. — Like Mercury compounds. Hyoscixe. — Similar to Belladonna, but chlo- ral is used here with great advantage. Hyoscyamcjs (and Hyoscyamine). — See Bella- donna. Igxatia. — See Strychnine. Iodine. — Empty the stomach (mustard, zinc sulphate, apomorphine, pump) ; follow with starch diffused in hot water or as a paste, or flour in warm water; farinaceous substances (arrow-root, boiled rice, thin gruel); demulcent drinks; may inhale amyl nitrite and relieve the pain by opium and morphine. Laburnum Seeds. — See Cytisine. Lactucarium. — See Opium. 157 Laudanum. — See Opium. Lead Compounds (Lead Chromate and Ace- tate; Barium Compounds). — If acute, empty the stomach (mustard, zinc sulphate, apomorphine, pump) ; follow with sulphate of magnesium or sodium, or dilute sulphuric acid; milk, demul- cent drinks. For the pain give opium or mor- phine; for lead colic, apply hot fomentations. If it be chronic lead poisoning, recognized by a blue line (sulphide) along the margin of the gums, paralyzed extensors, constipation, etc., give iodides to saturation (sodium and calcium iodides being best) ; sulphurated potassa baths. Lobelia. — If the patient has failed to vomit, use emetics; follow with tannin, stimulants, strycnnine, opiates. Lunar Caustic. — See Silver Compounds. Matches. — See Phosphorus. Mercury Compounds (also Copper Com- pounds). — Empty the stomach (mustard, zinc sulphate, apomorphine, ipecac, pump) ; follow with albumin (white of one egg to every 4 grains of corrosive sublimate. Too much must not be given lest the precipitate formed by the mercuric salt and albumin be redissolved. Now give an emetic — warm water with sodium bicarbonate, zinc sulphate, or mustard, and wash out the stomach with demulcent drinks (flaxseed or elm). If egg white is not conven- ient, one may use for mercury salts, gluten, wheat flour in paste form, milk, or chop and diffuse in water fresh meat and administer the broth. Morphine for pain. For copper com- pounds also use stimulants; relieve the pain 158 with opium or give reduced iron or wealv solu- tion of potassium ferrocyanide; then potassium iodide until the system is saturated to promote elimination. Morphine Salts. — See Opium. MuscARiisE. — See Mushrooms. Mushrooms (and Poisonous Fungi; also Mus- carine). — Empty the stomach (mustard, zinc, sulphate, apomorphine, pump) ; inject at once solution of atropine, or after emesis give tinc- ture of belladonna every half hour; castor oil and enema to remove fungi from lower bowel; stimulants; the body should also be kept warm. Nicotine. — See Tobacco. Nitrates. — See Chlorates. NiTROBExzENE. — (Oil Mirbaue). — Empty the stomach (mustard, zinc sulphate, pump), wash- ing it out with plenty of warm water if possible. Give stimulants by the mouth, the rectum or hypodermically; artificial respiration which must be maintained by weak, interrupted cur- rents to the chest wall. Rouse the patient by the douche; hypodermic atropine may be use- ful. Nitroglycerin — Like Amyl Nitrite. Nitrous Oxide Gas. — See Chloroform. Nux Vomica. — See Strychnine. Oil Bitter Almond. — See Acid Hydrocyanic. Oil Mibrane. — See Nitrobenzene. Opium (also Laudanum, Morphine, Codeine Lactucarium, Cannabis Indica) — When the poi> son has been taken by the mouth give at once a solution of potassium permanganate, then empty the stomach, which may be difficult, by 159 pump, apomorphine, mustard or zinc sulphate. Wash the stomach out well with hot coffee, leav- ing there a pint or more; keep the body warm with hot wraps, but use alternate hot and cold douches to the head. Use hypodermic solution of atropine every 15 minutes for three doses; tannin and strychnine are also valuable. Apply electricity to chest muscles and artificial res- piration. Keep the patient awake by shaking, flicking with a towel, applying cold water over the face and chest, keep patient moving; give inhalation of amyl nitrite. Evacuate the blad- der often to prevent reabsorption. Pkenacetix. — Like Acetanilid. Phosphorus (as well as Rat Poison and Matches). — Empty the stomach (copper sul- phate, until the patient has vomited sufficiently; zinc sulphate, mustard, pump — the copper form- ing insoluble black phosphide). Follow this with old (oxygenated, acid, French) oil of tur- pentine in mucilage or floating on water; may also inhale diluted turpentine vapor; give char- coal or lime water to prevent action on tissues; also magnesium sulphate as a cathartic. Po- tassium permanganate, opium, and egg white may be of service, but never use fats or fatty oils, as these dissolve phosphorus, thus aiding in its absorption. It is mostly eliminated by the urine, hence the bladder should be fre- quently evacuated. Physostigma (and Physostigmine). — Evacu- ate the stomach (mustard, zinc sulphate, ipecac, apomorphine, pump) ; hypodermic of atropine until pupils dilate. Should this fail, give 160 chloral, or hypodermic of strychnine. Diffusi- ble stimulants, coffee, alcohol, etc., are used and artificial respiration should be induced if neces- sary; empty the bladder often. Phytolacca — It acts ]ier se as an emeto-ca- thartic, hence after the vomiting give stimu- lants, alcohol, ether, opium, digitalis. PiCROTOXix. — See Strychnine. Pilocarpus (and Pilocarpine). — Evacuate the stomach, follow with hypodermic of atropine, or tincture of belladonna, until pupils are dilated; may give tannin. PoTAssA. — See Alkalies. Potassium Bichromate and Chromate. — See Chromic Acid. Potassium Cyanide. — See Acid Hydrocyanic, Potassium Nitrate. — See Chlorates. Prussic Acid. — See Acid Hydrocyanic. Pulsatilla. — Give tannic acid and follow with an emetic; alcohol, opium, or digitalis may also be indicated. Rat Paste. — See Phosphorus; also Arsenic. Rhus Toxicodendron. — Rub in a saturated solution of lead acetate in diluted alcohol, and repeat for several days; 5% solution or 10% oleate of cocaine is also effective; a solution of 2 drams of lead acetate and 4 drams of ammon- ium chloride in 8 fl. oz. of water has also been recommended. Internally, opium or coffee may be used to relieve the nervous irritability. Sabadilla. — See \eratrum Viride. Savine (oil and tops; also Tansy). — If not vomited and the throat not inflamed, evacuate the stomach with mustard, zinc sulphate, ipecac. 161 pump. If the bowels have not moved freely, give either castor oil or epsom salt; allay pain with morphine and demulcents. SciLLAiN (Scillitin). — See Digitalis. ScoPARius. — See Digitalis. Silver Compounds. — Give common salt dis- solved in warm water, to form insoluble silver chloride; or use egg white or milk; (follow with an emetic (mustard), and large draughts of warm water; give demulcent drinks (arrow- root, elm, flaxseed, gruel). Snake Bites. — Suck the wound and apply to it an alkaline solution of potassium permanga- nate (may inject this under the skin). In se- vere cobra poisoning, with ■ death threatening, bleed at one limb and transfuse blood by the other; give artificial respiration and weak in- terrupted galvanic shocks to the walls of the chest; inhale and give ammonia by the mouth. Soda. — See alkalies. SoLANiN. — See Belladonna. Staphisagbia (Stavesacre). — Evacuate the stomach (emetics, pump, draughts of warm water; give tannin, charcoal, diffusible stimu- lants. Keep the patient quiet and the extremi- ties warm. Give chloral hydrate, or potassium bromide; or better inhale chloroform for the spasms. Use all haste as death is usually caused by asphyxia. Stings (Bees, Hornets, Wasps). — Apply am- monia water or some alkaline solution to the part stung; extract the sting; use stimulants, if necessary. One may apply an onion to the part, but this is not as good as ammonia. 162 Stramonium. — See Belladonna. Strophanthus (or strophanthin) . — See Digi- talis. StrycHxXIne Salts (or Brucine, Ignatia, Nux Vomica, Picrotoxin, Cocculus Indicus). — Re- move the patient from all noise, quickly empty the stomach (mustard, zinc sulphate, apomor- phine hypodermically) ; give tannin, charcoal, iodide of starch. Place the patient under chloroform, ether, or chloral and potassium bromide, thus keeping up gentle narcosis sev- eral hours if necessary; inhale amyl nitrite. If spasms threaten respiration, induce it arti- ficially; empty the bladder often. SulfOxXal axd Trional. — Give diuretics and saline cathartics; sodium bicarbonate and wa- ter freely. Sulphuretted Hydrogen. — Resort to artificial respiration and inhalation of chlorine diluted with air; or give chlorine water or chlorinated lime. Tansy. — See Savine. Tartar Emetic. — See Antimony Compounds. Tin Compounds. — Evacuate the stomach (mus- tard, zinc sulphate, ipecac, etc.). Give milk of calcined magnesia; demulcent drinks (elm, flaxseed, etc.) ; laudanum if there is much pain. Tobacco (or Nicotine). — Concentrated ene- mas and large quantities of powder kill in a very few hours. If the patient has not already vomited the drug, empty the stomach by mus- tard, zinc sulphate or pump; give plenty of water; let the patient lie down; inject a solu- tion of strychnine nitrate or give tincture of 163 nux vomica by the mouth; stimulants, brandy, whiskey, chloric ether, etc.; keep the body warm but apply cold douche to the head; tannin and astringent solutions may be given. Turpentine. — Empty the stomach (mustard, zinc sulphate, ipecac, apomorphine, pump, tube). If there is no purging give enema, plenty of water and demulcent drinks to eliminate it by the kidneys. Apply hot fomentations to the loins. Allay the pain with opium. Tyrotoxicon (in milk, cheese, ice cream, etc.). — Give emetics and rinse out stomach; follow with purgative enema. Veratrum Viride (also Veratrine, Sabadilla, Veratrum Album). — Evacuate the stomach (un- less the veratroidine constituent has ejected itself by causing vomiting), by mustard, zinc sulphate, ipecac or pump. Give recumbent po- sition, head lowest; dry warmth to the body, wraps, blankets, etc.; give hot coffee by the mouth or rectum; tannin, diffusible stimulants, alcohol, brandy, whiskey, ammonia, morphine, electricity, artificial respiration; atropine an- tagonizes the cardiac depression. White Precipitate. — See Mercury Com- pounds. Zinc Compounds. — Should the patient not vomit, use plenty of warm water containing car- bonate or bicarbonate of sodium, or mustard; follow this with white of egg and milk; solution of tannin or strong tea to form insoluble tan- nate; allay the abdominal pain by hot fomenta- tions, morphine or tincture of opium.
