The Laboratory wing contains on the upper floor a large 
room designed for about 12 senior students, and, on the 
ground floor, six small work-rooms for researchers, a small 
library, a store-room, a dark room for photography and a 
workshop. Consequently there is accommodation for about 20 
students and researchers working simultaneously. 
For the last three or four sessions these rooms have all 
been fully, or more than fully, occupied during the spring 
vacation. In 1908 the numbers were 20 students and six 
research workers; in 1909 there were 21 students and nine 
researchers; and this present year the numbers during four 
weeks in March and April reached 40 in all (30 students and 
10 professional Zoologists doing research). These 40 workers 
represented the Zoology departments of at least six 
universities. 
This overcrowding is satisfactory in one sense, as it is 
gratifying evidence of the success of the institution, but it is 
unsatisfactory in other respects since it causes discomfort, less 
perfect work, and some complaints. Every student and every 
scientific man who has visited the institution at the busy 
season lately has been convinced that the laboratory and 
library accommodation ought, if possible, to be increased 
without delay. 
The only possible extension, on the Government land 
allocated and enclosed in 1901, would be a wing running back 
from the East end of the present Laboratory towards the 
cliff (left-hand upper corner on the accompanying plan). A 
building in such a position, 42 feet by 17 feet and two storeys 
high could be erected for about £300, including heating, 
lighting and simple laboratory fittings. In the lower floor it 
would provide an extension of the library and store-room, an 
experimental tank room and two additional laboratories, 
while on the upper floor would be a series of eight little 
work-rooms for researchers, looking out four to the East and 
four to the West. 
In the hone that when these facts were made known, some 
friend of the Liverpool Marine Biology Committee, wishing 
to encourage both the original investigations into marine life 
and also the teaching of senior students, might be willing to 
provide the necessary funds for such an addition, I 
obtained plans from Mr. J. McArd (the builder at Port Erin
