Thus, in the daily diet of the horse under labour there are 

 251 oz. of heat and fat givers, 59.1 oz. of flesh-formers, and 

 19.39 oz. of ash or mineral matter. 



In the first daily diet, or that under rest, the heat and fat 

 formers constitute not far from a half of the whole quantity, 

 the sum of the articles in ounces being 272, while the sum of 



272 



the heat and fat givers therein is 150 oz., - - = 1.8. In 



150 



the same diet the flesh-formers constitute no more than a 



272 

 ninth part, = 9.4, where 272 is the sum of the diet 



in ounces, and the divisor, 28.9, the total of the flesh-formers 

 in ounces. Again, in the same diet the sum of the mineral mat- 

 ter is 13 oz., or nearly a twentieth of the whole. In the second 

 daily diet, or that of the horse under labour, the sum of all the 

 articles of food in ounces is 448. Of this number of ounces, 



251, or less than two-thirds, -- = 1.78, are heat and fat

It may be remarked further from these figures, in the com- 

 parison between the daily diet of the horse at rest and his 

 daily diet under exertion, that in the labour-diet the heat and 

 fat givers, in round numbers, are increased by two-thirds of 

 their original quantity, the flesh-formers are doubled, and the
