264 PHARMACOPCEIA. 



In a well constructed stable, some mi thocl 

 may ea>ily be found for reguiatinp, the tem- 

 jjcrature of the air, and making it either 

 cold or warm ; for this purpose a thermo- 

 meter should always be employed. Old 

 horses that have been accustomed to warm 

 stables, become lean and unfit for work if 

 placed in a colder situation, though their 

 allowance of corn be increased. External 

 warmth is (juite a cordial to them, and 

 gives them health and spirits; but on no 

 occasion do we recoumiend those hot, close 

 stables, soiiighly valued by grooms, thongh 

 a very prolific source of disease. The stable 

 should be always properly ventilated, and 

 the bod^' kept waruib}- clotliing, adapted to 

 the season of the year, and the temperature 

 of the air. 



TONIC^5. Medicines that augment the 

 vigour of the body permanently, and are 

 therefore useful in all cases arising from de- 

 bility.
