analysis gave 8.04% HjO and 5. 65% Ca, instead of the theoretical 8.01% 

 HjO and 5.53% Ca. 



The cadmium salt forms beautiful needles, readily soluble in water. Its 

 analysis showed 8.21% HjO and 14.13% Cd, instead of 8.29% HjO and 

 14.19% Cd. 



The zinc salt consists of indistinct needles, readily soluble in water. Its 

 analysis showed the presence of five molecules of water, and 10.51% Zn. 



The methyl ester crj^stallizes in beautiful needles, which melt at 104- 

 105° C. By its combustion I obtained 26.23% C and 2.15% H. Its for- 

 mula requires 26.86% C and 1.68% H. 



The study of other mixed dihalogen derivatives of salicylic acid is being 

 carried forward in this laboratory, the results of which will be published 

 later. 



IV. Barite from Ludlow Falls, Miami County, Ohio. 

 By Charles H. Ehrenfeld. 



This mineral was found in the summer of 1886, the chief interest in 

 connection with it being that it is the first time barite has been found in 

 this locality. It is white, semi-transparent and massive, and it occurs in 

 the Niagara limestone, associated with small crystals of pyrite, the surface 

 of which is brown owing to oxidation. The average of four sp. gr. deter- 

 minations of the barite is 4.48. 



An analysis showed the following composition : 



BaSO^ 91.10 % 



SrSO, 7.63 " 



CaSO, 98 " 



Total 99.71%
