On Beetroot Fu/p. 
101 
Allowing only little for the superiority of sugar as a fattening 
•element of roots, the case is far from overstated if 1 ton of 
English sugar-beets is considered as equivalent in nutritive 
properties to at least IJ ton of common mangolds. In the next 
place, let us compare the preceding analyses with the average 
comparison of the refuse pulp from beet-root sugar manufactories. 
In round numbers this may be stated with sufficient accuracy 
.as follows : — 
Average Composition of Beet-root Pulp (^Be/use Pulp of Sugar 
Manufactories . ) 
Water 70-0 
Sugar 1"5 
*Albuminons compound (flesh-forming matters) .. 2"5 
Crude fibres and a little lactic acid 24'0 
Mineral matter (ash) 2-0 
100-0 
* Containing nitrogen '40 
In 100 parts of pulp it will be seen there are 30 per cent, of 
<lrv matter, whereas 100 of sugar-beet from which it is obtained 
contain only 15^ parts of dry substance, and common mangolds 
but 11 parts. 
A ton of beet-root pulp accordingly contains 672 lbs. of dry 
matter, or 325 lbs. more than a corresponding weight of the roots, 
and 425i more dry matter than 1 ton of common mangolds. 
In other words, 1 ton of pulp contains not quite, but nearly, the 
same amount of solid substances as 2 tons of Silesian sugar- 
Jbeets, or 3 tons of common mangolds. 
Nobody probably will dispute the fact that the dry substance 
of a sugar-beet or a mangold is more valuable for feeding and 
fattening purposes than the dry substance of the pulp. The 
question, however, which requires to be settled is, not whether 
the perfectly dry pulp is less valuable than perfectly dry roots 
from which it is made, but whether the 672 lbs. of solid matter 
contained in a ton of pulp are worth more or less than the 347 lbs. 
of solid matter present in a ton of sugar-beets, or 246^ lbs. of the 
jsolid matter of which common mangolds consists. 
A further comparison of the preceding analyses shows tliat, 
weight for weight, the pulp contains more albuminous (flesh- 
forming) matter, much more fibre, and but little sugar. On the one 
hand we have in sugar-beets an excess of 8 per cent, of sugar, and 
in common mangolds an excess of 4 per cent, over the amount of 
sugar in the pulp ; and, on the other hand, we have 24 per cent, 
of fibre in the pulp against 3i in beets, or 3 per cent, in common 
mangolds, besides an excess of 1 per cent, of albuminous matter 
in the pulp.
