THEIR FEED AND THEIR FEET. 63 



viz. : fat and water. These substances endow the 

 heaviest bodies with a comparatively low specific 

 gravity, giving, at the same time, to the constitu- 

 tion, little power of resistance." 



The German scientists are very much interested 

 in Dr. Jaeger's discoveries, and have great faith in 

 them. No one there doubts that he has discovered 

 and proved beyond cavil that the power of the human 

 body to resist disease depends upon its specific grav- 

 ity, and this unquestionably is a valuable discovery 

 to the medical profession. 



• It is manifestly true that the soundness of the tis- 

 sues and their specific gravity must depend upon the 

 quality and quantity of the ingesta, including the 

 kind of air habitually breathed, and upon the balance 

 maintained between the amount of work performed 

 and of food eaten. Upon the wisdom displayed in 

 carrying out these views or considerations depends 

 the power of the organism to maintain that just 

 balance which we term health. 

 It is not essential to fix the exact 



AMOUNT OF FOOD NECESSARY 



for any and every horse, so that the owner may 

 we^igh and measure exactly in proportion to the work 

 or iexercise his horse is doing. Horses differ some- 

 what as to their needs (less, however, than is usually 

 supposed) — some working harder than others to ac- 

 complish the same service — but it is entirely out of 

 reason for a horse averaging only fifty to seventy- 

 five miles buggy-riding a week to consume as much
