immediately after work relieves the blood of excessive 

 thickening and consequent sluggishness, while it does no 

 harm.

 proportions to different animals. They are necessary for 

 the formation of muscles, and blood-serum is the vehicle by 

 which the proteids of food find their way into the various 

 tissues. Febrile diseases result in excessive using up or 

 cumbustion of proteids. Hence the need of foods rich in 

 proteid matter, such as milk, soup, carrots, grass, bran mashes 

 and linseed and other gruels, during and after febrile attacks. 

 An excess of proteids, on the other hand, produces congestion 

 which results in local inflammations, and susceptibility to 

 pathogenic diseases, as the bacteria find a suitable nutrient 

 soil in blood containing an excess of albuminoids. 



i ,042. Fat is also burnt up largely in wasting diseases, and 

 as fat is necessary in the respiratory process for the production 

 of heat and animal vitality, its repair by means of proper 

 carbonaceous food is necessary. All the muscular tissues 

 are more or less associated with fat which makes them 

 pliant, and joint-oil or sinovia is necessary to prevent concus- 

 sion between bony surfaces. Where fat is present the 

 combustion of muscular tissue does not take place to any 

 appreciable extent for the respiratory function. Hence the 

 presence of fat saves the muscular tissues from oxidation or 

 burning. On the other hand, an excess of carbonaceous or 

 fatty food, results in debility and interference with the vital 

 activity of the cells of the body, and comparative stagnation 

 of the circulator} 7 system. If such food is persisted in infil- 

 tration of fat takes place inside the tissues of important 

 organs, and finally fatty degeneration or actual conversion 

 of these tissues into lumps of fat.

 observed in the various constituents of food, such as water, 

 albuminoids, and carbonaceous food, holds equally true as
