SHE EGG OF AMIA AND ITS CLEAVAGE:

PREFACE. 
THE search for the eggs of Amia, begun by Louis Agassiz, 
and renewed from time to time by others, was first successful 
May 1, 1887, when the senior author of this paper found nest 
and eggs in Pewaukee Lake, Wisconsin. There has been no 
lack of interest in the search on the part of American natural- 
ists, but a number of reasons conspired to delay the discovery. 
The nature of the breeding-grounds and the habits of Amia 
were little understood, and those most interested in securing 
the material lived at long distances from the more promising 
localities. 
The difficulties in the way of the first discovery seem to be 
little appreciated by those who have recently collected these 
eggs and made free use of information well known to have 
originated with one of us, but with no acknowledgment, except 
to parties who were either wholly innocent of anything but bor- 
rowed knowledge of the subject or had acquired their first 
information under our guidance.
