The Composition of Proprietary 

 Preparations. — A number of queries to 

 the composition of proprietary remedies 

 have been answered by t-elephone during 

 the past month, by reporting analyses 

 published by chemists in various bureaus 

 devoted to such work. For various rea- 

 sons, at this time we will not print the 

 answers to such queries, but will refer 

 our readers to the two publications of 

 the American Medical Association, "The 

 Propaganda for Reform in Proprietary 

 Medicines" and "Nostrums and Quack- 

 ery" as well as to the Bulletins of the 

 food and drug departments of the States 

 of Connecticut, Ohio, Indiana and North 

 Dakota, all of which we have in the 

 library. 



Names of Manufacturers. — We glad- 

 ly furnish our querists with information 



concerning the manufacturers of goods 

 handled by the drug trade, but for 

 obvious reasons, such answers are not 

 published in this department. 



A Batch of Prescription Queries. — J. 



G., New York. Evidently appreciates 

 our information bureau, for he has for- 

 warded to us for criticism a batch of 

 prescriptions that fairly swamp us. We 

 shall, however, dispose of them to the 

 best of our ability.

He reports that a moist mass resulted, 

 but that he remedied the situation by 

 using caffeine alkaloid, both with and 

 without sugar of milk. He wishes to 

 know whether the addition of sugar of 

 milk is advisable. 



The incompatibility of antipyrine with 

 citrated caffeine is mentioned in Ruddi- 

 man's classic work on incompatibilities 

 and the remedy used by J. G., the em- 

 ployment of one-half the quantity of the 

 alkaloid is correct. We would add an 

 equal amount of sugar of milk to make 

 the powder have the prescribed weight. 

 And, lastly, we would notify the pre- 

 scriber of the mianipulation employed, 

 with reasons for the modification.

As the prescriber was not a resident 

 of New York and as J. G. could find no 

 recipe for such a preparation he dis- 

 pensed boric acid containing 5 per cent, 

 of zinc sulphate.
