them in his paper. I need not recall to you how neatly he 
made this investigation, and represented some of the results, 
filling the comb with plaster-of-paris and then cutting it across 
midway, so that the observations might be made and the cells 
measured just where they are most aie perfect ; and then 
printing impressions of the comb upon the wood-block, he re- 
produces on the pages of his article the exact outlines of the 
cells, with all their irregularities and imperfections. But I 
cannot refrain from citing a portion of his remarks at the 
close : 
zi Hen ere, as is so often the case elsewhere in nature, the type- 
form is an ideal one; and with this real forms seldom or never 
coincide; sai e< An assertion, like that of Lord Brougham, 
that there is in the cell of the bee ‘ perfect agreement’ between 
theory and observation, in view of the analogies of nature is 
more likely to be wrong than right; and his assertion in the 
case before us is certainly wron Much error would have 
been avoided if those who have discussed the structure of 
the bee’s cell had adopted the plan followed by Mr. Darwin, 
and studied the habits of the cell-making insects compara- 
tively, ee with the cells of the humble-bee, following 
with those of wasps and hornets, then with those of the ne X1-

have from him, but know not if he ever 228s it. ‘ No single 
experiment in physiology é is worth anythin 
As Dr. Wyman arks in a note to the second series, “ the 
recent experiments of “Dr. Child of Oxford, and those reported 
in this communication, are sufficient answer to the eriticisms
