100 On tlie Composition and Nutritive Properties of 
In short, all tlie soluble constituents of mangolds, more espe- 
cially the sugar, are much more sparingly present in tlie pulp 
than in the root ; and the insoluble matters, especially crude woody 
fibre, are more abundant in the pulp than in the root itself. 
Since there is nearly 3^ per cent, more water in the pulp 
than in the root, the comparison of the pulp in its natural state 
with the fresh root does not bring out as strikingly the changes 
which mangolds experience in the distiller's hands as would be 
the case if l)oth contained the same amount of water. I have, 
therefore, calculated the composition of the two mangold-roots 
in a perfectly dry state, and placed in the subjoined Table the 
results side by side with those which represent the composition 
of the two specimens of dried pulp.

* There is scarcely any sugar included in these numbers. 
The preceding figures suggest the following observations : — 
1. In the same state of dryness mangold-wurzel contains 
2i times as much sugar, gum, and soluble pectinous compounds 
as the pulp. 
The average proportion of these soluble organic matters in the 
two roots, dried at 212° Fahr., and analysed by me, is 62-12 per 
cent. In the dried pulp the average of the two samples is only 
24-4. There is thus a difference of 37-9, or 38 per cent, in 
round numbers, in favour of the mangolds. 
2. On the other hand, in the same state of dryness, the pulp 
contains nearly double the quantity of albuminous compounds 
that is found in the root. 
The average proportion of albuminous compounds in the dry 
mangolds is 8-66 ; in the pulp it is 15-64 — thus leaving a differ- 
ence of 7 per cent, in round numbers, in favour of the pulp.
