small quantity of pliosplioric acid in combination witli lime 

 and mag-nesia. It agrees very closely in tliis respect with, 

 tliat of the ox and the horse; in which no trace of phosphate 

 has yet been detected. It abounds also, like the urine of 

 these animals, in salts of potash and soda. It is especially 

 rich in common salt, and in soda, which in the ash is in the 

 state of carbonate, but which in the urine is no doubt com- 

 bined with some organic acid. If it be natural to the urine 

 of healthy sheep to contain so much soda, we may find in 

 this one reason why they relish salt so highly, and thrive so 

 much better when it is abundantly supplied to them. The 

 org-anic portion of the urine contains, in 1000 parts, —

Art. XV.— steamed FOOD FOR PIGS. 



Quoted by Mr. Fennell. 



In Wade's British History it is stated, that a g-entleman in 

 Norfolk put six pigs, of nearly equal weight, on the same 

 food and litter for seven weeks. Three of the lot were kept 

 as clean as possible with a curry-comb and brush, and were 

 found to consume, in seven weeks, fewer peas by five bushels 

 than the other three, yet weighed more when killed by two 

 stones and four pounds, on the average : a strong' argument 

 in favour of keeping' -^i^s person ally clean.
