The first trial shows a gain of 36 per cent. (almost double 
the average), and the second a gain of 15 per cent. by the 
starch method. Three other trials gave each a gain of 15 
per cent., and a fourth trial gave a gain of 23 per cent. 
By the usual method is meant that the eggs were kept in 
motion and the milt washed off rather slowly. A trial of 
the method of allowing the eggs to adhere, and afterward 
separating them, showed a gain of about 5 per cent. over 
the usual method, but a disadvantage of 10 to 15 per cent. 
as compared with the starch method. 
Thus out of a considerable number of experiments there 
is an average gain of about 20 per cent. by the use of the 
starch method ; so that the method certainly merits a trial 
on acommercial scale. It is always possible to handle a 
small number of eggs, as a few thousands, in such a way 
as to secure a very large percentage of fertilized and unin- 
jured eggs. The extreme care in manipulation, which is 
necessary to accomplish this, cannot be used where the 
number of eggs is so greatly increased and where the 
conditions for working are so unfavorable, as is usual in 
commercial practice. By the use of starch, eggs may be 
handled with very much less trouble than by the methods 
now in vogue, so that the method may be of value, even if
