Remarks ivpon Dr, Christison's Memoir, " On the Detection of 

 minute Uuantifies of Arsenic in mixed Fluids,^* By R. Phillips, 

 FRS. L. and E. &c. 



In^ the seventh volume of the Annals, New Series, I published 

 a paper on the subject of arsenic, one object of which was to 

 render the methods usually resorted to more easy of application^.: 

 and another that of pointing out a method of destroying theij 

 colour of fluids suspected to contain it> by means of animal char- 

 coal. 



The Edinburgh Medical and Surgical Journal (July, 1824), 

 contains a communication on the detection of minute quantities 

 ofarsenic, by Dr. Christison, Professor of Medical Jurisprudence. 

 The author of this paper, after mentioning Orfila's method of 

 decolorizing suspected fluids by the action of chlorine^ observes.
