ANALYTICAL ASSOCIATIONS. 



analytical associations, properly constituted and satisfactorily 

 managed, the sum of 10s. for each complete analysis, and 5s. 

 for each partial analysis of manure or feeding stuff analysed 

 through its asrencv. 



There is a considerable amount of trouble incurred in the 

 management of analytical associations, and the most of it 

 devolves upon the secretary, who, unless he is an enthusiast in 

 the cause, cannot be expected to devote his time and energy to 

 the association's work without some remnneration, and if the 

 increased expense involved in carrying out the Society's 

 regulations has hitherto deterred any associations from accepting 

 these, it is hoped that the augmentation of the grant may tend to 

 remove that difficulty. 



Among the manures and feeding stuffs supplied to the mem- 

 bers of associations were a few whose analysis may be of interest 

 to others besides those for whom they were performed. 



Calf Food. — A feeding stuff called " Lactina," and another 

 called " Calf Food," were supplied to the members of the Lanark- 

 shire Association. 



They were sold without an analytical guarantee, and were 

 found to contain — 



Lactina, Calf Meal, 



per cent. per cent. 



An3unmioid matter, . 14-00 11-25 



Oil, 2-27 6-92 



Carbohydrates, . . 68-39 69-48 



The former was sold at £24 per ton, and the latter at £26 

 per ton. 



Other samples of lactina and calf meal, which were analysed 

 by me during the past year, had the following composition : — 



It will be seen that the composition of these substances 

 approaches very closely that of barley meal. In some the 

 amount of oil is considerably more than is found in barley 

 meal, and approaches more nearly to that contained in Indian 

 corn meal. 



Compared with average linseed cake, they contain less than 

 half its albuminoid matter, and nearly double its carbohydrates. 

 They have therefore a wide nitrogen ratio, and a correspondingly
