COMPARATIVE ANALYSES OF BONES PREPARED 
BY STEAM AND BY CRUSHING. 
At the monthly meeting of the Highland and 
Agricultural Society of Scotland, in February last, 
a new method of reducing bones to a high state of 
division was submitted by Mr. James Blackhall, of 
Edinburgh. His process, the details of which 
have been published in different agricultural jour- 
nals, consists in exposing the bones for a certain 
length of time to the action of high-pressure steam, 
by which, according to Mr. Blackhall's statement, 
they are brought into a much higher state of divi- 
sion, and at a much less cost, than by the ordinary 
method of crushing. Mr. Blackhall's original idea 
was, that the bones were thus dissolved, and he 
conceived that his process would replace the com- 
mon method of solution by means of sulphuric acid. 
The following are the results of two analyses of 
bones by Dr. Anderson, the society's chemist, pre- 
pared by the new process — No. i. by Mr. Blackhall, 
and No. h., which w r as sent to the laboratory for ana- 
lysis, by George Cranstoun, Esq., of Corehouse : —

In order to form a correct estimate of the advan- 
tage of Mr. Blackhall's method, it is necessary to 
compare the composition of these bones with that 
of those prepared by the ordinary process, as it is 
very evident that a certain proportion of the gela- 
tine, or glue, which is very soluble in boiling 
water, must have been extracted by the steaming. 
In looking into the subject, however, Dr. Anderson 
was unable to find any analysis of bones in the 
state in which they are used as a manure, and he 
found it necessary to analyze several specimens of 
agricultural bones, of which the following are the 
results :— No. i. were drill bon'es, in pieces about 
an inch in length. No. n. ordinary finely-crushed 
bones ; and No. in. the entire bones in the state in 
which they are sold to the bone crushers by the 
persons who collect them : — 
i. n. in. 
Water, . . 10.00 10.39 14.79 
Animal matter, . 41.88 42.60 37.02 
Bone earth, . 48.12 47.01 48.19 
100.00 100.00 100.00 
From a comparison of these analyses with the 
former, it is manifest that they contain much more 
animal matter than the steamed bones, the amount 
averaging 40 per cent. ; while in the latter, in one 
case, we have only half that quantity, and in the 
other about 27 per cent. Now it must be very 
clear that, in the production of a ton of steamed 
bones, it is not sufficient to reckon the mere cost of 
steaming in addition to that of the crude bones, 
but that the loss of animal matter must be taken 
into account. Supposing the crude bones to con- 
tain exactly 40 per cent, of animal matter, a very 
simple calculation shows that they must lose 25 
per cent., in order to yield a substance which shall 
contain 20 percent, of animal matter. Supposing,
