LIGHTING — TEMPERATURE. 37 



culty, let the windows already shown be adopted, or borrow 

 from the heavens by means of skylights, either fixed or 

 movable. Where ventilation is good, immovable skylights 

 will answer, but when this is not the case, the lights may 

 be made movable by hinges, with cords by which to open 

 and shut them at will, or durin"; storms. A dark stable 

 is usually a dirty and ill-ventihited one, prone to produce 

 diseases of a typhoid or low condition of the vis vitse. The 

 light of the sun admitted into a stable, is as potent in pre- 

 serving animals in health, as darkness is in the cause of 

 decay and disease. The dose of sunshine is as regularly 

 prescribed, and with as much benefit by the physician in 

 certain afi"ections, as any article in the pharmacopoeia. 



The temperature is an important matter in the man- 

 agement of places where animals are kept, yet the ther- 

 mometer is an instrument seldom consulted, even if it finds 

 a place. This should not be, especially in a climate such 

 as ours, where we have the mercury at zero at one hour of 

 the day, and at another 20° to 30° above it. The difficulty 

 in regulating the temperature, or rather in keeping the 

 degree of heat in winter up to the summer standard, is 

 more apparent than real, even if it were necessary. 



The stable temperature of summer being from 70° to 

 90°, would obviously not only be unnecessary, but highly 

 injurious to the horses in winter, with the thermometer 

 indicating zero in the open air. Coughs, colds, staring 

 coats and chills, swelled legs, and a train of other ills, 

 would be of constant occurrence, and some of the horses
