EXPERIMENTAL MICROSCOPY—SOMMERS. SI 
White Fish, and 8000 Salmon Trout, the latter having been ob- 
tained from the lakes of Ontario. He has at the present time 
(April, 1879) 1,800,000 Salmon hatched, and in a few days will 
commence to distribute them among the most suitable rivers 
within reach’ of the hatchery. This will make a total of 4,800,000 
salmon distributed from this one hatchery, in the short space of 
four years. The Bedford Establishment, although one of the 
smallest in the Dominion, has a hatching eapacity of 2,500,000. 
There are at present eight fish-breeding establishments in the 
Dominion: two in Ontario, four in Quebec, one in New Bruns- 
wick, one in Nova Scotia; and it is proposed to erect an addi- 
tional one, during the present summer, in New Brunswick.  P. 
E. Island is certainly entitled to one. There will probably be 
distributed during the next four weeks from the hatcheries now 
in operation, within the Dominion, about 40,000,000 young fish, 
of which about 30,000,000 are the White Fish of the great lakes 
of the west. No doubt the culture of the Trout, the Oyster and 
the Shad will receive attention in Canada at an early day.

Tuis short essay owes its existence to a wish expressed by 
members of the Council of the Institute. 
It contains nothing original, or what any person familiar with 
the use of the Microscope, does not already understand. It was 
prepared to accompany a series of experiments presented to the 
members, and it does not pretend even to explain the nature of 
these, nor of the specimens exhibited. 
The writer feels complimented in that he has been requested 
to fill at the final meeting of this season, a vacancy which has 
occurred for the first time for many years. One who never 
failed to present the results of his observations at the final meet- 
ing of the session, has closed his earthly labors. Endeared as he 
was to us all, not only for his zeal and arduous toil in the cause
