198 THE LIFE OF A FOXHOUND. 



being boiled, is converted at once into blood. 



"All animals partaking of a mixed diet, 

 partly of grain, will be greatly influenced in 

 their respiratory organs by the proportions 

 which are given to them and the state of the 

 atmosphere. The quality of the blood being 

 regulated by the quantity and the quality of 

 food consumed, its capability of passing 

 through the lungs is governed. When an 

 animal has partaken largely of food which 

 renders the blood of that character as to cause 

 the consumption of a great quantity of oxygen 

 in its passage through the lungs, and the 

 atmosphere is deficient of that important gas 

 — ^which is always the case in close damp 

 weather, such as is occasionally experienced 

 during the winter — it follows, as a matter of 

 course, that hounds, and all such animals, 

 will quickly evince symptoms of distress, or, 

 familiarly speaking, will become blown, as the 

 causes which produce that effect predominate. 



** In hot climates man consumes very little, 

 if any, animal food; in cold ones, scarcely 

 anything else : and the Esquimaux will par- 

 take of blubber, animal oils, or fat — a food 

 nauseating and disgusting to the people of 

 another climate.
