Motion — the whole round of functions of which the organism 
is capable, depend on the exciting and directing action of nerve- 
organs. 
For those who desire to pursue the study to which the pre- 
ceding remarks form a simple introduction, the following works 
will be found useful : — ' Chauveau's Comparative Anatomy,' by 
Dr. George Fleming; 'Principles of Human Physiology,' by 
Dr. Carpenter ; ' Kirke's Handbook of Physiology,' by Morant 
Baker. Of these the first-named is to be selected as the most 
comprehensive and useful for the student of anatomy in refer- 
ence to the animals of the farm. 
III. — Pasteur and his Work, from an Agricultural and Veterinary 
point of View. By Geoege Fleming, LL.D., F.R.C.V.S., 
Principal Veterinary Surgeon of the Army. 
Agriculture, in the widest and most comprehensive sense of 
the term, depends upon so many collateral sciences, as well as 
arts, for its continuous prosperity and progressive develop- 
ment, that any marked advancement or important discovery 
in these must react more or less beneficially upon it, and pro- 
mote, to a commensurate extent, its welfare. Among the 
sciences which, for many years, have aided in this direction, 
perhaps it is not too much to claim for Chemistry a very forward, 
if not the foremost, place ; and among the greatest chemists 
are those who have devoted at least a portion of their skill and 
time to the study of what has been termed "Agricultural 
■Chemistry." The chemical composition of soils in relation to 
the food, growth, and health of plants ; the food, feeding, and 
products of certain animals, as well as the preparation and^ pre- 
servation of many of those products for the use of man ; the 
action of the atmosphere, heat, light, and moisture upon plants 
and animals ; the artificial agents which may be made to second 
the efforts or supplement the exhausted powers of nature, whether 
in regard to the soil, the plant, or the animal body — in all 
these, and in other ways, chemistry has lent its powerful 
assistance to agricultural requirements, and it may truly be said 
that, without it. Agriculture would lose one of its best benefactors 
and most worthy helpmates. 
In recent years, the science of Biology has also been bestow- 
ing more and more of its favours on Agriculture, and is now 
pushing Chemistry very hard for the first place in respect to the 
services it can render the oldest of all the arts, and more
