TEMPERATURE — SLEEPING-ROOM. 39 



between two doors, where the cold would be such as to give 

 rise to disease. This, then, is the chief reason of the more 

 perfect immunity from chills, leading to thoracic diseases 

 in summer, amongst horses, and at the same time illustrates 

 why it is that from the heated stable in winter, horses are 

 more subject to influenza, pleurisy, pneumonia, &c. How 

 necessary, then, is it, that a thermometer, properly protected 

 from injury, should be placed in every stable where valu- 

 able horses are kept, and the keeper instructed in its use — 

 charging him that the mercury be kept at a given place in 

 the tube during the day, and at something higher during 

 the night ? The standard or relation of the heat of the 

 stable to the open air at all seasons of the year, night and 

 day, is so difficult to attain and control, that we could only 

 approximate to it were an attempt made to give figures ; 

 but we would say that the stable should be 10° to 20° 

 warmer in winter than the open air, and in summer per- 

 haps as much cooler, which can only be done by door or 

 window currents of air, or placing horses underground in 

 cellar stables, with a northern exposure of the building, or 

 where the rays of the sun do not strike its walls. 



The sleeping-room over the stable is of so much 

 importance in stable management, when jDroperly conducted 

 in its various details, that few persons will run the risk of 

 their horses getting loose from their stalls during the night, 

 without some one in the building to secure them before any 

 injury is done to horse or stable by kicking and biting, as 

 is often the case, when no one is on the premises to inter-
