186 Annual Report. 



These constituents combined together represent the composition 

 of the water as fqllows : — 



Grains. 



Organic matter 1'51 



Oxides of iron and alumina, and traces of pliosplioric acid .. 1*15 



Sulphate of lime 14'4G 



Carbonate of magnesia 3"78 



Carbonate of lime 1G"37 



Chloride of sodium 13"67 



Nitrate of potash 19-24 



Soluble silica 1*95 



Total residue in tlie gallon 72-13 



It is hardly necessary for me to add that such a water is totally 

 unfit for drinking, and bad for all domestic purposes.

 beans, a powerful irritating poison. The cake in question was 

 sent to me for examination, on account of the serious mischief 

 which it had done when it was given even in very small quan- 

 tities to cattle. 



Analyses. 



The number [of analyses made for members of the Society 

 during the past season was fully as large as in former years. 

 Soil and water analyses were more numerous, and guano and 

 artificial manures fewer, indicating that the trade in manures is 

 more and more carried on by respectable persons. 



Cottonseed Meal. 



I beg to direct attention to the high-feeding value of crushed 

 cotton-seed, from which a portion of the coarse and indigestible 

 husk is removed by sifting. A sample of such cotton-meal on 

 analysis gave the following results i — •
