It is obvious that the additional food administered in the form of 
pulverised (ground) rusk has operated very favourably, and in general 
no less than in the experiments with unbroken rusks. (Table 11). 
So far the experiments on the influence of rusk (fat) as additional food. 
Now the question had to be settled whether bran, or bolted meal 
(flour) either with or without the addition of rusk, is of equal 
nutritive value to the larvae. 
For this purpose it is necessary to revert to the jars N°. 4 (M.P.) 
N°. 5 (B.R.) and N°. 6 (M.R.) mentioned in Table I. 
From these groups the following numbers of pupae had already 
been gathered on the Febr. 10, 1916 (as stated in Table J) 
from N°. 4 (M.P.) 13 pupae.

The collecting of pupae was continued till July 8. Then the 
experiments were closed, the collected pupae counted, the mortality 
of the larvae figured out, and the remaining larvae weighed. This 
yielded the following results, also ineluding those of experiment 
N°. 2a (of Table II), which may serve for comparison.

From the above figures it is evident that bran with rusk a 
additional food had a much more favourable effect than meal + rusk ;
