EGGS OF PIKE-PERCH— 6'. Vitreum. 

 By Fred Mather. 



On April 25 of the current year I had some eggs of this 

 fish in hand. They were not in good order on receipt, but 

 there were hopes of some. On looking uj) the literature of 

 the hatching of pike-perch, but little was to be found 

 beyond statistics, and that little was in the reports of this 

 Society, in an article by Mr. James Nevin. On measuring 

 the eggs, my estimate of the number in a quart greatly 

 exceeds that of Mr. Nevin, who gives it as 100,000. 



From my notes, taken at the time of receiving the eggs 

 (in water), I find the following : the eggs measure thirteen 

 to the linear inch, 109 to the square inch, and 2,197 to the 

 cubic inch. As there are 57,775 culnc inches in a quart, 

 there would seem to be 126,931 eggs in it ; but the above 

 calculation is made on the supposition that the eggs would 

 be piled \\.\) in such a way that their diameters are in line, 

 thereby wasting the greatest space in the interstices. As 

 this is not the ase, I have, after careful counting and esti- 

 mating, added 350 eggs to each thousand for this filling of 

 chinks, and in this case the addition would be 44.450, 

 making the total number of jDike-perch eggs in a quart to 

 be, in round numbers, 171,000, which I believe to be nearly
