is intended to facilitate their formation. Sucrate of lime 

 and the intravenous injection of ammonia are both also 

 recommended. In the case of the cats above referred to, 

 20 grains of zinc sulphate speedily acted in one instance, 

 and was followed by egg albumin in milk, and every three 

 hours by a mixture of chlorodyne and lime water. In a 

 second case, the emetic proving ineffectual, the animal died. 

 With the large animals strong purgatives and whisky have 

 proved successful when the purge acted. The horse ^ made 

 a speedy recovery after oil of turpentine. 



Chemical Diagrnosis. — Carbolic acid and its allies, being 

 volatile, may be recovered from organic matter by distilla- 

 tion from the acidified mass in a current of steam. They 

 are recognised in the distillate by their odour, by the ferric 

 chloride coloration (carbolic acid gives a violet, creosote a 

 smoky tint), and by the formation of the sparingly soluble 

 bromination compounds — a crystalline solid in the case of 

 carbolic acid, and gummy in the case of the cresols.

STRYCHNINE. 



Forms and Occurrence. — The alkaloid strychnine occurs 

 along with brucine and igasurine in the . seeds of certain

 East Indies ; the Strychnos Ignatii in the Philippines ; the,
