Messrs. LLOYD BROTHERS. 

 Gentlemen : 



I have bought in the Baltimore market 

 a bottle of "Lloyd's Hydrastis," and find upon 

 examination that it gives with Mayer's solution an 

 abundant quantity of a white curdy precipitate, 

 which when further examined unmistakably proves 

 to be of AN ALKALOIDAL NATURE, and con- 

 tains NEITHER COMPOUNDS OF ALUMINUM 

 NOR MAGNESIUM. If the compounds of the 

 latter elements are eliminated from the liquid by 

 precipitation, the filtrate gives the same abundant 

 quantity of an ALKALOIDAL PRECIPITATE with 

 the above mentioned or with other suitable re- 

 agents. 



Very respectfully, 



W. SIMON, Ph. D. 



OTHER ANALYSES WILL FOLLOW. 



LLOYD BROTHERS.
