January 17th, received from Howietoun a box containing 
45-eyed salmon ova, varying in size from 0:20 to 0°25 of an inch 
in diameter, the large ones having been taken November 19th 
from a 16lb Teith fish, and the small eggs from one of inferior 
size from the same river. About four were dead on arrival. 
February 8th, three of the eggs out of twenty-three were 
found to have hatched. As these were taken on November 
19th they were eighty-one days up to the period of hatching, 
and on being hatched they were half an inch long. On the 
16th two eggs hatched, and they were all out by the 21st 
except one. Most came forth head first, the shell splitting 
down the back. 
On February 21st one of the fish was completely out of the 
shell except its head. It had attempted to enter the world tail 
first, and was now like a cat with its head in a stocking. 
Several ineffectual attempts were made to release it by means 
of brushes, and so on the 27th, feeling satisfied that unless 
freed it would die, took a sharp pair of scissors and succeeded 
in inserting one end and then dividing the shell. As the fish 
constantly wriggled about care had to be taken not to cut it. 
This fish subsequently did well. There were no monstrosities 
among these fish. 
January 19th, 1 p.m., placed three eggs in a tumbler of salt 
water, of the specific gravity of 1,021°. On the second day 
they became slightly cloudy, and they were found to be all 
dead after three days’ time. The water having been changed 
daily, similarly to the experiment on trout eggs, as well as in 
the following ones. 
January 22nd, 10 a.m., repeated the foregoing experiment. 
All were dead at the end of three days. 
January 19th, 10 a.m., placed three eggs in a tumbler of 
salt water at 1,012°. They were all dead in three days and five 
hours. 
January 28th, 11.30 a.m., placed two eggs in a tumbler of salt 
water at 1,012°. Next daya little cloudy. Died on the eighth day. 
January 28th, 11.30 a.m., placed two eggs in a tumbler of 
brackish water at 1,007°. The water seemed dirty, and on 
February Ist they were dead.
