Mr. Titcomb: We are able to do it in some cases now. 
Prof. Reighard: If you wait till all the dead eggs have 
formed gases enough to float them, you might separate all of 
them at one time without having to pick over the eggs at all,— 
assuming, of course, that the formation of the gases in the dead 
ros would not further injure the lving eggs.

Mr. Titcomb: I do not know as I brought out one point 
developed in this experiment, that I intended to mention. You 
know you have many unfertilized eggs which retain the color of 
the live eggs for a long period, especially in cold weather, and 
if you want to pack the eggs when they are barely eyed, for a 
40 or 50 day shipment, it is difficult to eliminate all those unfer- 
tilized eggs. If you put those unfertilized eggs in salt water 
and then back into fresh water, it causes them to turn white 
more quickly. That might be preferable to jarring the eggs, 
as they eall it, giving them too much of an agitation to get the 
dead eggs out. 
Mr. Lydell: I would like to ask Mr. Titcomb if the object 
of this chart is to establish bases for the measurement of eggs 
at different stations. All the eggs I received from the United 
States Fish Commission this year, which were measured, overran. 
Out of 100 quarts in one instance, I made the eggs measure 108 
quarts, and I thought I was very careful in measuring them; but 
this chart, as I understand it, is to establish a basis for each sta- 
tion in different localities, inasmuch as the eggs are of different 
sizes in different. localities, and not to establish a general law 
for measurements everywhere. 
Mr. Titcomb: Yes sir. 
President: Your statement as to the variation in measure- 
ment of the eggs you received, illustrates what Mr. Titcomb said, 
to the effect that no two men will measure the same eggs exactly 
alike, nor will the same man get the same results twice. 
Mr. Lydell: | doubt whether the same man could measure 
100 quarts of wall-eyed pike eggs twice alike. 
Mr. Titcomb: My purpose in suggesting the use of the 
trough and chart scale is simply to have a standard for each sta-
