questions of the practice of morals, and the nature of the future 
life. The evolution of mind consists of a continual advance from 
the ‘known into the unknown, and a transfer of the unknown 
to the known. So long as there is any inducement to progress ` 
of this kind, and nature responds to inquiry, development will 
goon. Although it is true that it is only among men, and but few 
men at that, that the pursuit of knowledge is an ‘occupation; 
most men add to their stock incidentally as they pursue other 
avocations. The knowledge of right and the inducements to its 
practice are learned in their every-day intercourse, so far as it can 
be acquired. But knowledge in these directions soon attains its 
limit, and accordingly, development. dependent on knowledge 
must cease. If any further progress in practical morals is to be 
made, some new force must intervene at this point. 
‘Here is the opportunity for the appearance of will or spon- 
taneity ; here it is at least needed. I am willing to believe that it 
May appear at this point, and that so long as we have to face the 
unknown in moral progress, so long it will remain. As a force 
it must be equivalent of other forces, but as a form of con- 
sciousness it is a new element of mind. As represented in 
new molecular organization, it may always continue, even after 
much of the unknown may have been conquered, and a station- 
ary period may have ensued. Such an accession to character 
would be a fitting crown of evolution, and a justification of - 
this labor of the ages. If a true factor in human development, 
it might be compared, in the creation of character, to the apical 
bud of a growing tree. As the part preéminently living, it leads 
the growth of the trunk and branches. They all follow of neces- — 
sity the path it has marked out. Under its lead they are suc- 
cessively formed, become fixed, and finally decay.

THE TONGUE OF THE HONEY BEE. 
BY PROF. A. J. COOK. 
HE bee is, and has long been, of great imp 
cial world, and this, together with the fascination inseparable 
from its study, have led many of the ablest scientists to carefully 
investigate its structure and habits. Yet I know not if there ex- 
ists to-day an accurate description of a bee’s tongue, and the 
method by which the insect procures its food.
