MARINE BIOLOGICAL STATION ON PUFFIN ISLAND. 35 
large colony of Aleyoniwm digitatum, and afew Amphipods, 
nothing was obtained. 
It had been intended to anchor for the night in Douglas 
Bay, but during the dredging and trawling the vessel had 
drifted so far out of her course that when evening came it 
was found advisable to run for Ramsey. Here half the 
party went on shore for the night, the rest staying on 
board for the electric-light experiments, which will be 
described further on. 
On the following morning an early start for the south 
was made, the rest of the party was picked up at 
Douglas, and then the work of the day commenced. 
The ‘‘Hyzena’’ steamed slowly round the east and 
south coasts of the island to Port Hrin (see map, 
fig. 1, second day), dredging and tow-netting at intervals, 
with very good results. When a stop was made for 
collecting the fullest advantage was taken of it. The 
sounding-line and the deep-sea thermometer were over 
amidships, and two dredges, a large bottom tow-net, and 
one or more surface nets were put out astern. The deep 
tow-net, devised and worked by Mr. W. 8. McMillan, was 
so weighted and buoyed as to work steadily at a distance 
of a foot or so above the sea-bottom, and it yielded a large 
amount of material, which was in some cases conspi- 
cuously different from the contents of the surface-nets, 
worked by Mr. I. C. Thompson, during the same time. 
The latter supplied very large numbers of Anomalocera 
patersoni, a Copepod which Mr. Thompson reports had 
been taken very rarely before, and never since, in our 
district. Some of these surface animals apparently exist 
in local shoals. This Copepod, although very abundant 
along the south-eastern coast of the Isle of Man, was not 
present in tow-nettings taken off Puffin Island during the 
same day.
