slieep about 9 lbs., and pigs from 4 to 5 lbs. of the dry substance 
of thoir respective foods. 
Produce of Manure in the Wohurn Experiments. 
On the present occasion we shall only call attention to the 
amounts of /VcsA and dry dung obtained for given amounts ot 
food and litter employcil ; leaving the question of the chemical 
composition of the manure in relation to that of the food and 
litter, for separate consideration at a future opportunity. 
In Table VII. (p. 207) the total amounts, and in Table VIII. 
(p. 208) the average amount, per head per week, of food, litter, and 
dung (both fresh and dry), are given separately for each of the six 
experiments. In Table XIII. which follows, the amounts per 
head per week, and per 100 lbs. live-weight per week, and also 
the amounts of food and litter yielding 1 ton of fresh dung, taking 
the average of the six experiments, are given : —

Thus, taking the average of six experiments, extending over 
an average period of nearly eight weeks, and including 44 animals 
of a mean weight of aliout 1470 lbs., there were consumed per 
head per week, about 43;^ lbs. of cake or corn, llOf lbs. clover- 
hay chaff, and 377 lbs. roots ; in all 531 lbs. of food. There 
were used besides, 133 lbs. of litter. The total food and litter 
was therefore 664 lbs. ; and the amount of fresh dung produced 
was 575 lbs. The dry substance of the dung was 156 lbs., that 
of the litter being only 106| lbs. ; there was a gain therefore of 
about 50 lbs., or nearly one half, upon that of the litter used. 
The dry substance of the food and litter together was, however, 
276 lbs., yielding in dung 156 lbs., or only 56-| per cent, of the 
total. 43^ per cent, of the dry substance of the food and litter 
were, therefore, either stored up as increase, expended by the
