188 Mr GUAHAM'S Account of the Formation of Alcoates. 



14.8 grains were reduced by heat to 8.8 grains. This gives 6 

 grains alcohol to 8.8 grains nitrate of lima The atomic weight 

 of anhydrous 'nitrate of lime is 10.25. Now, 



8.8 : 6 : : 10.25 : 6.98. 



In another case, 15.6 grains were reduced to 9-2, which gives 

 6.4 alcohol to 9.2 nitrate of lime. But, 



9.2 : 6.4 : : 10.25 : 7.13. 



This approaches 7.1875, or two and a half equivalent proportions 

 of alcohol. The composition of the alcoate of nitrate of lime 

 would be represented on this view, by 



Two atoms nitrate of lime, . 20.5 

 Five atoms alcohol, .... 14.375 



34.875 



In another strong alcoholic solution of nitrate of lime, a few 

 irregular crystals were deposited, but the quantity was not suffi- 

 cient to admit of examination, although they proved that this 

 alcoate is capable of crystallizing. 



4. Alcoate of Protochloride of Manganese. 



The protochloride of manganese, dried in a glass-tube, at a 

 red heat, was light, friable, and of a reddish colour. Alcohol dis- 

 solved a very large quantity of it. When the solution was made 

 at a high temperature, the alcoate crystallized readily upon cool-
