that of farmyard manure, such as kainit, sulphate of 

 ammonia, and mineral superphosphate. 



The experiments upon the use of artificial foods consumed 

 upon grass lands with a view to the improvement of the 

 herbage have also been continued, as regards i' the value 

 of artificial food in fattening sheep, and (2 the manurial 

 value of food so consumed to the land upon which the 

 experiment was carried out. The best results in feeding 

 the sheep were obtained with linseed cake, which also 

 yielded slightly better results in the weight of the grass ; 

 but this grass was not so productive of dry matter as that 

 grown upon cottoncake-manure. 



With the object of obtaining information on the question of 

 the effect of various substances used as food " preservatives " 

 upon the health of animals, a mixture of borax and boracic 

 acid was added to the food of a certain number of pigs. The 

 result, so far as the experiment was carried, served to show 

 that the animals did not suffer any injury from a moderate 

 use of these antiseptics ; and, in fact, it would appear that 

 for pigs, at least, such use of borax is to a certain extent 

 useful.
