under my notice cases of poisoning, upon which the bulk 

 of the analytical data of the text is based. 



As regards the botanical parts of the work, I have had 

 the advantage of the expert help of Mr. E. M. Holmes, F.L.S., 

 of the Pharmaceutical Society, who perused all the plant 

 descriptions given. 



The abstraction of original papers in the veterinary 

 literature was performed by my wife. Had it not been for 

 this assistance, involving many hours of close and uninter- 

 rupted work, the preparation of the text would scarcely have 

 been possible in a reasonable period of time. 



Free use has been made of the textbooks, and I am 

 particularly indebted to Pinlay Dun, 'Veterinary Medicines '; 

 Winslow, ' Veterinary Materia Medica '; Gamgee, ' Veterin- 

 arian's Vade - Mecum ' ; Nunn, ' Toxicology ' ; Cushny, 

 ' Pharmacology '; Kaufmann, ' Traits de Matiere M6dicale'; 

 Cornevin, ' Des Plantes V^n^nenses '; Gadamer, ' Lehrbuch 

 der chemischen Toxikologie '; Walsh, ' South African 

 Poisonous Plants '; and Bentham and Hooker, ' British 

 Flora,' upon which the botanical descriptions are based. 



I hope that egregious blunders will prove to be few in 

 number, and shall welcome errata, and especially notes of 

 cases from my veterinary friends both at home and abroad.
