Miscellaneous Analyses. 



Examinations for Metallic Poisons. 



Four samples of material have been sent for investigation. 

 Three examinations were made at the request of the Cattle 

 Commission of the State. The material sent consisted in these 

 cases of the stomach and some of the adjoining organs with 

 their contents, besides the liver, bile and bladder of three 

 cows. Two of these specimens came from Ashfield and one 

 from Enfield, Mass. In the first case — from Ashfield — there 

 was found a considerable quantity of copper, apparently due to 

 presence of fine scraps of brass among the contents of the 

 stomach ; in the others no metallic poison could be detected. 

 The fourth case came from Amherst, Mass. The material for 

 examination consisted of the stomachs, with contents, of 

 chickens. A considerable quantity of arsenic acid was proved 

 to be present. 



Analyses of Maple Sap for Mineral Constitiients. 



[Sent on from Goshen, Mass. I. Sample from an old tree, sp. gr., 1.015, at 23° C. 

 II. Sample from a young tree, sp. gr., 1.010. at 23° C] 



The examination was made to ascertain the relative amount 

 of lime present in both saps. The difference is but slight, as 

 may be seen from the above analyses.
