Should these eggs be kept in a damp, cold, and dark place, 
still the embryo may continue to develop, even without their 
being immersed in water, as has been proved by transmitting 
them thus packed in safety to the Antipodes. I was shown at 
Howietoun on February 27th, 1886, a number of Lochleven 
trout eggs taken on December 19th, when they had been placed 
in an incubating tray, from whence they were removed on 
January 22nd to a box in damp moss, on which a little ice was 
placed, and they had been thus kept in a room where a tem- 
perature was maintained of between 40° and 44° Fahr. The 
embryos to all appearances were doing well. I took this box 
of eggs with me on March 2nd to Cheltenham, and the next 
morning placed some of the ova in water in an incubating tray, 
but the majority were left in the moss. The eggs in the tray 
commenced hatching on March 26th, when ten young came 
out, two days subsequently on looking at the eggs which had 
been left in the moss, several were found to have hatched, and 
some live alevins were present, which Mr Wethered and I 
removed along with the remainder of the eggs to a hatching 
tray, where they did well.

damp moss where they had been 34 days, and placed them in a 
tumbler of water indoors, in a room where a fire was kept 
during the day. On March 12th I added twelve more eggs 
from the moss to those in the tumbler, and all were transferred 
to the conservatory, where only a moderate amount of heat 
was maintained. The water was changed once daily, some 
being kept for this purpose in a jug alongside the tumbler in 
order that the temperature of the two should be the same. On 
March 16th, at 8 a.m., two eggs were found to have hatched, 
the young were pretty lively, but the yelk-sac seemed to be of 
the normal shape, only a little large; on the 17th, two more 
emerged, three on the 18th, and the last eight on the 19th. 
In this experiment the eggs had been removed from the water 
(where they had been 34 days), and subsequently kept in cold 
and damp moss from a period varying from 47 to 50 days, and 
then placed in water kept moderately warm, — where they 
hatched within a week.
