the fat which becomes deposited throughout the living frame, 

 that deposit being the overplus at any time laid up for future 

 use in the function of animal heat. It will be convenient, 

 then, in speaking of the animals of the farm, to join the two 

 epithets, and to call such proximate principles the " heat-giv- 

 ing and fat-forming substances." In the 12 Ib. of hay belong- 

 ing to Professor Dick's first diet, as above, there are 103 

 oz. of heat-givers and fat-formers, 16.7 oz. of flesh-formers, 

 and 11 oz. of mineral matter. In the 5 Ib. of oats belonging 

 to the same diet, there are 47 oz. of heat-givers and fat-form- 

 ers, 12.2 oz. of flesh-formers, and 2 oz. of mineral matter; 

 these results being brought out thus : 



192 oz. : 103.0 oz. heat and fat givers. 

 192 oz. : 16.7 oz. flesh-formers. 

 192 oz. : 11.0 oz. mineral matter. 



80 oz. : 47.0 oz. heat and fat givers. 

 80 oz. : 12.2 oz. flesh-formers. 

 80 oz. : 2.0 oz. mineral matter. 



There are thus, in the normal diet of the horse at rest, 

 150 oz. of heat and fat givers, 28.9 oz. of flesh-formers, and 

 13 oz. of mineral matter. 



In the 14 Ib. of hay belonging to Professor Dick's second 

 diet, there are 120 oz. of heat and fat givers, 19.48 oz. of flesh- 

 formers, and 13.66 oz. of mineral matter. In the 192 oz. of 

 oats belonging to the same diet, there are 114 oz. of heat and 

 fat givers, 29 oz. of flesh-formers, and 4.8 oz. of mineral mat- 

 ter. In the 32 oz. (2 Ib.) of beans belonging to the same diet, 

 there are 17 oz. of heat and fat givers, 10.4 oz. of flesh- 

 formers, and .992 oz. of mineral matter; these results being 

 brought out thus :
