cells only. Sixth, probably the primitive cells of the mesoderm 
are amoeboid in character. For all mesodermic cells, not mechan- 
ically united with other cells, but capable of independent locomo- 
tion by amoeboid movements, is proposed the collective name of 
“ mesameabotds.” The author concludes by saying that if these 
views are confirmed “we shall then have discovered primary /zs- 
tological differences between the three germinal layers in their 
earliest stages as follows: 
EPITHELIAL. 
A. Small cells, mainly protopl ti Ectoderm 
B. Large cells, with much deutoplasm.... Entoderm 
ÅMŒBOID. 
C. Cells free in the cavity between the two primitive layers, ecto-

Ant BATTLES.—I have within the past few years witnessed 
several battles between ants, and in some instances, the curious 
conduct of the captors towards their prisoners which I think is 
worth mentioning. The most noted battle took place July, 1878, be- 
tween two colonies of red ants. The victorious army were med- 
ium in size and numbered many thousands; those captured were a 
much larger ant, but not so numerous. The large ants after a 
desperate resistance were forced out of their fort, four or five small 
hausted and then allowed to go free—<A. Miller, North Man-

New Zealand, enumerated several species which were common to _ 
that country and America; these are Neptunus sayi, Platyonich
