her condition was somewhat higher than that of Mr. Smith's. 

 When the experiment was begun, on the 1st of January, no per- 

 ceivable difference was found in the yield of milk of Mr. Smith's 

 cow and my own, each giving 15-3 quarts per day. 



The following Table gives the dates of calving of the three 

 cows, together with their weights and yield of milk at the com- 

 mencement and termination of the experiment : — 



Mr. Smith's cow lost in weight in nine weeks 84 lbs., being 

 Oglbs. per week, with an average yield of 12 1 quarts per day. 

 Mr. Pawson's lost 28 lbs. : this loss, together with the dimi- 

 nished yield of milk, occurred almost wholly after the oats had 

 been withdrawn. Her weight on the 6th of February being still 

 7 cwt. 2 qrs., and her yield of milk, 11 quarts per day. 



My cow has gained, in the nine weeks, 56 lbs., being 6j lbs. 

 per week, with an average yield of 14 quarts, the diminution being 

 regular. January 1st, 15i ; Feb. 4th, 14; March 4th, 12^; 

 making an average yield of 14 quarts per day. The whole loss 

 and gain of weight will be in flesh and fat, the cows having 

 kept up their consumption of food and their bulk. 



The weekly account of profit and loss will stand as follows : —
