1823.] Mr, R. Phillips on James's Powder, 191 



sisted chiefly of bone earth. These differences are referable to 

 the mode of preparing it ; but in almost every case, a very large 

 proportion of the protoxide is lost during the process, and 1 have 

 found it a matter of great difficulty so to conduct it as to obtain 

 upon the large scale an uniform product. For medical use, I 

 should consider emetic tartar as the only certain and necessary 

 preparation of antimony." — (Manual, vol. ii. p. 180.) 



It will be observed that without recollecting Mr. Brande's 

 recommendation of emetic tartar to the exclusion of all other 

 antimonials, I ventured to give similar advice ; and I would 

 conclude with remarking, that if it be possible to urge satisfactory 

 reasons against a preparation, such reasons are contained in the 

 passage I have quoted from Mr. Brande. It shows that pulvis 

 antimonialis may consist almost entirely of phosphate of lime, or 

 that it may be a mixture of phosphate of lime, and peroxide or 

 protoxide of antimony ; and it is a perfectly well-estabUshed fact, 

 that fifty times as much peroxide of antimony may be given as 

 of the protoxide ; that the large dose is inert, the smaller one 

 may be dangerous, and yet to this uncertainty is the physician 

 exposed, although he may not be persuaded that " he can 

 never have derived any benefit from the exhibition of antimonial 

 powder."
