Pharmacopoeia Professor Hertwig’s ( Praktische Arznei- 
mitellere fur Thievarzte ; 5 and Moirand’s ‘ Traite Elemen- 
taire de Matiere Medical en Pharmacologie Veterinaire . 5 
With such mines of knowledge as here lie open to him 
(to which he might have added those of Bourgelat and 
Delafond on the Continent ; to say nothing of veterinary 
productions of the same class, scanty though they be, of our 
own country,) it was Mr. Dun’s fault if he did not compile a 
creditable work. But he has not merely done this ; he has 
produced one of first-rate order, — one that will soon be in 
the possession of veterinarians on this side of the Tweed as 
well as on the other, — and which will, for the time to comes 
stamp him as one of the stars of the veterinary profession. 
The extracts we are about to make from the work will, 
we opine, fully bear us out in the high character we have given 
it. Beginning with the 
“ INTRODUCTION. 
“Veterinary Materia Medica, in the extended sense of the term, 
treats of every agent, material or immaterial, which is used for the cure of 
disease or injury, or for the preservation of health among the domesticated 
animals. The subject may be divided into two parts — Zootherapeutics and 
Zoohygienics. 
“ Zootherapeutics (Z&ov, zoon, an animal ; and Qepourev, therapeuo , I cure) 
treats not only of the material substances used in veterinary practice, as 
drugs or medicines properly so called, but also of all the immaterial or im 
ponderable agents, as heat, light, and electricity, and all the mechanical and 
surgical remedies which the practitioner has occasion to call to his aid. It 
also includes Veterinary Pharmacy, which consists in the collection, pre- 
paration, preservation, and dispensation of veterinary drugs. 
“ Zoohygienics (£wov, zoon t an animal ; and vyuivog, hiigieinos , healthy) 
treats of all that affects the sanitary condition of animals. It includes 
dietetics, and inculcates the best modes of maintaining warmth, cleanliness, 
and efficient ventilation in the houses and sheds intended for the accom- 
modation of stock. 
“But as the full discussion of Veterinary Materia Medica, under these two 
divisions, would require a treatise far exceeding the limits of the present 
work, it is my intention to confine my observations solely to that branch of 
the first part of the subject which is sometimes styled Veterinary Pharma- 
cology, or the description of the medicines or drugs used in the cure of 
disease among the domesticated animals. 
“ As, however, the different medicines thus used possess many actions in 
common, and are prepared by the same pharmaceutical processes, I purpose 
prefacing the consideration of individual medicines by a few remarks on the 
general actions of medicines, and on the more important operations of 
pharmacy. These subjects will be discussed in two .sections.
