CoLCHicuM (Meadow saffron root) is a diuretic medicine 

 to the horse. It also acts upon the liver, and can be 

 administered in cases where the exhibition of calomel is 

 inadvisable. In very large and dangerous doses it is a 

 purgative. It is a favourite agent for the cure of rheuma- 

 tism, as likewise for circumscribed affections of a painful 

 nature as periodic ophthalmia. The powder or tincture 

 are the two preparations in use among veterinarians. 

 The extract is too expensive. 



CoLLYRiuMs are washes commonly in use for the eyes. — See 

 Washes. 



Conserves. — The conserve of red roses is a most convenient 

 medium for forming balls, as it is adhesive, and, when 

 properly made, keeps well. 



Cordials are matters that invigorate by their stimulating 

 property, usually through the medium of the stomach. 

 Cordials have been so long the very strong hold of the 

 ignorant and presuming, that the very term sounds ill 

 in the ear of the well-informed veterinarian. The groom 

 requires a cordial, because his daily and perhaps hourly 

 habits tend to derange his stomach, which can only be 

 brought to feel appetite when re-st:mulated by the cor- 

 dials that are fast hastening him to his end. But his horse 

 indulging in no such habits, does not require a cordial ball 

 twice a week ; or on every evening after hunting ; or on 

 every morning his coat stares with the altered tempe- 

 rature : to the animal, a cordial, as being unnatural, 

 must be hurtful, unless required by some very extra- 

 ordinary exertion ; which, by calling forth too much of 

 the constitutional powers, has expended the vital re- 

 sources whence the stomach draws its tone. Thus 

 after a very hard run with hounds ; after thirty, forty, or 

 fifty miles' rapid carrying, this may happen ; and then a 

 gentle stimulant may excite the digestive sympathy arti- 

 ficially. Here a cordial may be proper and even neces- 

 sary : but a very good one can under such circumstances
