have been taken. The lines along which temperatures 
have been taken during the last three years on the hydro- 
eraphic cruises of the Lancashire Fisheries steamer 
are (1) from Holyhead to the Calf Island, (2) from the 
Calf Island to the Piel Gas Buoy near Barrow (along 
latitude 54° N.), and (3) from the Piel Gas Buoy to 
Maughold Head in the Isle of Man. This last line was 
given up aiter the first year’s work, and a new line has 
been added this year from the Calf Island to the Liverpool 
North-west Lightship. In addition various series of 
observations have been made in the Welsh bays further to 
the south; and on one occasion lately temperatures were 
taken in the deep water off the Mull of Galloway. 
The Irish Fisheries Authorities have taken tempera- 
tures in the past from the Calf Island across towards 
Ireland and alone several lines to the south of that from 
the Irish coast eastwards across the Channel. During 
this present winter it is understood that the new Irish 
Fisheries steamer has started a series of fresh lines of 
observing stations that will traverse the sea-area between 
the Isle of Man and Ireland at several different levels. 
These series will no doubt eventually give much needed 
information as to the physical conditions in the deep 
western channel, which differs so markedly in conforma- 
tion from the shallow eastern half of the Irish Sea in 
which the Lancashire observations have been taken. In 
the meantime, -as nothing has been published bearing on 
the deep-water area north of the Calf and west of the Isle 
of Man, it may be of interest to record the sea-tempera- 
tures taken on board the “ Ladybird ’ during her work 
outside Port Hrin in the spring and summer of 1908. 
Mr. Harold Drew, now of Plymouth, was on the yacht 
during the summer, and assisted in taking the following 
series of temperature observations. 
In April, the following surface observations were
