Experiments on the Feeding of Stock. 
those who are exposed to this scourge." In the following year, as 
sheep — chiefly aojed ewes — are abundant and cheap in the dis- 
trict, they were substituted for cow-stock; and of late 600 sheep 
have been fattened in the winter, producing GOO cwts. live weight 
of piime meat. 
Experience in dealing in stock has led !M. Reiset to make the 
following remarks : — " Marketing plays a prominent part in the 
lives of our agriculturists, and has for them a special attraction. 
If we inquire into the real means by which some among them have 
made fortunes, we shall often find that their prosperity is due to 
the skill which they display in repeated purchases and sales, 
rather than to their intelligence in the management of their land." 
These hints from practical life will prepare the reader to follow 
with livelier interest and more of faith the scientific researches, 
which form the bulk of the volume. 
The subjects treated of are : — 
1. Experiments on the composition of milk, taken at the 
beginning, middle, and end of the milking. 
2. Experiments on grain, in respect of its weight per measure 
and its specific gravity at different degrees of dryness and maturity ; 
the relation between the weight per measure and the nitrogen, 
or gluten, contained in the flour, and consequently its value as 
bread ; and the question of sale by weight or by measure. 
3. On the fermentation of dung, and on putrefaction. 
4. On sheep^feeding with mangold pulp. 
5. On the comparative feeding value of mangold given raw, 
steamed, or as distillery refuse. 
6. Analyses of several varieties of rape during the second year 
of groAvth. 
7. ^Movable sheep-sheds. 
8. Farm distilleries, their management, yield of sugar from 
mangold of different sizes and varieties — weight of crops. 
9. Experiments on the respiration of animals. 
Of these investigations some few will interest the practical 
man ; others concern the foundations on which science is slowly 
but surely built. No better evidence can be given of the utility 
of some of the points investigated than the fact that these also 
form the bases of Professor Coleman's estimates, as stated in his 
paper reported in page G23 of this Journal. The eminently prac- 
tical manager of the model farm and the man of science who farms 
for himself, come to view things in the same light, though their 
estimates exhibit slight variations. 
On the JFcif/Jit and Feeding Quality of Hlicat. 
M. Reiset made many experiments to determine the weight 
per bushel, and specific gravity, of the grain of various kinds of
