No. 144.] 359 



In Twenty-fourth street an average of 500 horses is kept Ib 

 stables upon two blocks for sale. The stables are mostly above 

 ground, yet those who use them are constantly in dread of aa 

 opthalmic disease, called the pink eye, which attacks horses from 

 the country, and injures their sale. It arises fiom the excess oi' 

 ammonia, and want of ventilation and light. If the floors were 

 kept white with plaster the disease would disappear. Disenfeo- 

 tors are scarcely ever used here in the city, where most needed. 

 Stables cannot be made too light, or with too much ventilation. 

 The government of this city should prohibit the stabling of horses 

 in cellars — it is a cruelty to animals, and a nuisance to peopk 

 ten times greater than city cemeteries. It is a much needed re- 

 form, that a reform Common Council may very well busy them- 

 selves about. The use of one dollar's worth of plaster, copperas, 

 sulphuric acid, or charcoal, all easily obtainable in the city^ 

 would often save one hundred times the cost, in preventing sick- 

 ness, or saving the lives of horses. Shall we ever learn to do 

 anything that our grandfathers did not do. 



Dr. Waterbury has composed the following table, in connectioa 

 with the matter of stabling animals. If we take from the carbon 

 of different kinds of food the excess of oxygen atoms over hydro- 

 gen atoms ; allowing two atoms of oxygen to one of carbon, there 

 will still remain an excess of carbon to be used in the system foi 

 the production of animal heat. If we designate the carbon heal 

 4ind the azote motion it will stand in this way 4 



Beefsteak, 1 lb. motion, 3 lbs. heat. 

 Oats, 1 do 16 do 



Hay, 1 do 18 do 



These items maybe regarded as types of the food of the twt) 

 classes of animals, the carnivorous and the herbivorous, and this 

 table is sufficiently exact for purposes of illustration. 



Is there any connection between the differences of their items 

 and the habits of the animals that feed on them 7 



Observation has shown us, that animals cannot use the one of 

 these elements of life, without disposing of a corresponding amount 

 of the other. Stage horses, hard driven, grow poor, though the
