ANSWERS TO QUERIES. 



Magnesium Peroxide. — S. M. P., 

 New York. — Magnesium peroxide MgOo 

 is prepared by treating sodium dioxide 

 with a double magnesium salt, prefer- 

 ably in the presence of an ammonium 

 sah. 



It is a white powder that should con- 

 tain not less than 15 per cent, of MgOo. 

 When brought in contact with water, 

 oxygen is produced, while treatment with 

 diluted acids produces a solution of 

 hydrogen dioxide. 



It is used as an antiseptic especially in 

 tooth powders and similar preparations. 

 For further details, S. M. P. is referred 

 to "New and Non-Official Remedies." 



The Composition of Proprietary 

 Preparations. — A number of queries to 

 the composition of proprietary remedies 

 have been answered by telephone 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.
