following article on the “ Importance of Ventilating Sta- 
bles/* &c. 
“ It was the intention of the Creator, that all animals, so long as they 
were permitted to exercise their natural instincts, and thus comply with the 
requirements of physiology — the science of life — should enjoy health and 
long life. Hence a great amount of disease and death results from the 
evils of domestication. 
“ One of the conditions, which physiology imposes, in order that a horse 
shall enjoy health, is : — that the atmosphere, at all times, and under all 
circumstances, shall be uncontaminated, so that the blood shall be de- 
carbonized and purified of the defiling elements acquired in the course of 
circulation. 
“ Let the reader understand that the lungs are something like a sponge, 
elastic, composed of a myriad of cells. In the former, however, these cells 
have a vast internal surface, communicating with each other up to their 
common origin, the bronchial tubes and windpipe. On their internal sur- 
face we find a delicate yet highly important membrane permeable to atmo- 
sphere ; in extent, it is supposed to occupy a square surface equal to that of 
the external body. In contact with this membrane comes the atmosphere. 
If pure— zephyr-like — it fans into healthful blaze the flame of life, up- 
heaving from the living Vesuvius arid lava, in the form of carbonic acid gas, 
almost as destructive to animality as that issuing from its great prototype 
proves to vegetation. 
“ The stable atmosphere being pure and the lungs in working order, the 
blood is well arterialized, capable of supplying the waste of the animal 
machine and renovating its tissues. 
“ On the other hand, should the atmosphere be impure, it fails to vitalize 
the blood ; the latter is unfit for the purpose of nutrition, and may be 
considered a non-supporter of vitality. Hence the need of pure air, the 
breath of life. 
“ JBut, are horses always furnished with pure air ? Let the owners of 
unventilated, crowded, filthy, down-cellar and low-roofed stables, answer. 
“ Let those who have stables in the region of swamp, sewer, and stagnant 
pools of water, answer. 
“ In such locations disease and death run riot, and the noble companion 
of man instead of being within the ramparts of the science of life, is on the 
margin of death’s domain. lie may exist for several days without food and 
water ; yet the consequent result is nothing, when compared to that occa- 
sioned by breathing an atmosphere highly charged with emanation's, arising 
from his own body excrements, and decomposing bedding. 
“ A horse is said to consume in the lungs, in the course of twenty-four 
hours, ninety-seven ounces of carbon, furnished by venous blood ; in order 
to perform this feat he requires 190 cubic feet of oxygen. Now suppose 
there are ten horses occupying the stable, they require in the same time 
1900 cubic feet of oxygen, and consume 970 ounces of carbon. They are 
supposed, also, to give out from the lungs a volume of carbonic acid gas, 
equal to that of the oxygen inspired ; and supposing the atmosphere to 
be saturated with only five per centum of the former, it is a non-supporter 
of life. 
“ Hence a horse shut up in an unventilated stable must sooner or later 
become the subject of disease ; the evil may be postponed but the day of 
reckoning is sure and certain. 
“ Diseases, such as horse-ail , influenza, catarrh , strangles , and glanders , 
often originate and prevail to an alarming extent in the unventilated stable
