Mangold- Pulp {Ike Refuse of Beet-root. Distilleries). 00 
it was given to them unmixed with any ()tli(>r food. Cows and 
sheep at first would not touch it ; on mixhig the pulp, however, 
with clover-chaff they did not object to it, and by degrees seemed 
to acquire a liking for the mess. 
1 shall presently give an account of some feeding experiments 
instituted with a view to ascertaining practically the comparative 
fattening value of the pulp and of fresh mangold-wurzel. Ihit 
as many persons entertain very erroneous opinions respecting the 
relative value of the different constituents of food, and their 
adaptation to particular purposes, and as it may be at all events 
interesting to most to trace the changes which mangolds undergo 
in the process of distillation, I shall briefly endeavour to describe 
these changes. We shall best comprehend this matter by com- 
paring the composition of the pulp with that of the mangold-root 
from which it is made. Two specimens of yellow-globe man- 
golds, analysed by me some time ago, were found to contain in 
100 parts : —

A comparison of these analyses with the preceding analytical 
results, representing the composition of pulp, will show — - 
1. That the proportion of water in the pulp is increased nearly 
3J per cent. ; 
2. That the sugar has almost entirely disappeared in the 
pulp ; 
3. That the proportion of crude woody fibre is very much 
larger in the pulp than in the root itself ; 
4. That notwithstanding- the larger amount of water in the 
pulp, it contains more albuminous or flesh-producing matter than 
the mangold-roots ; 
5. That the roots contain more soluble albuminous matters 
than the pulp ; and 
6. That the proportion of soluble mineral matters is more con- 
siderable in the roots than in the pulp,
