two dozens in number, and shifted to pond 16, all being small 
except two, one of which was twelve inches long and j-lb. 
weight. 
On November 28rd, 1886, 1,000 eggs were obtained from one 
of these fishes, which was 9:1 inches long, and had a shortened 
lower jaw. These were milted with a Lochleven trout, and 
about 700 hatched on February 10th, 1887, or in 79 days. 
June 27th 667 fish were removed to No. 1 pond at Howietoun. 
In September, 1888, they were looking well. In this instance 
we see the disastrous results of employing the milt of young 
fish for the purpose of breeding; still among the few survivors 
it is clear that not only hybrids raised between female Lochleven 
trout and male salmon may be fertile, but likewise that similar 
crosses, when a young salmon, or rather par is one of the 
parents, may afford fertile offspring. 
Having thus demonstrated from Howietoun experiments 
that salmon and trout may intercross, and likewise that their 
offspring may be fertile, if bred with one of the original parents, 
or others of the same genus, I may just mention that a cross 
between the female American char, Salmo fontinalis, and a 
salmon par proved fertile in 1884, a few of the eggs having been 
hatched. 
The succeeding Howietoun experiments refer solely to crosses 
made between English and American char and Lochleven trout. 
November 15th, 1882, about 3,000 eggs of the Lochleven 
trout were fertilized with milt from an American char: they 
hatched in 85 days. The mortality among the incubating eggs ~ 
was about one death in every 6 ova. The young were much 
malformed, monstrosities being numerous: some had blindness 
in one or both eyes, others had bulldog deformities of the snout ; 
some were very light-coloured, but not quite white, as the 
markings, although pale, were visible. July 20th, 1883, the 
remaining fish were transferred to a large wooden tank raised 
off the ground, and supplied with water from a stream, but it 
was rather exposed to the east. On March 12th, 1884, upwards 
of twenty were found to be dead, so the next day the rest were 
removed to the upper planked pond at Howietoun, into which
