MARINE BIOLOGICAL STATION AT PORT ERIN. 17 
tions (see fig. 3), with openings which can be blocked so 
as to regulate the flow of a trickle of water, or so as to 
retain a shallow pool. The largest of these sorting tables, 
about 12 feet in length, is placed in front of a range of 
eight windows, and will no doubt be most useful for the 
examination and classification of the minuter animals 
brought in with sea-weed, zoophytes, and other more 
bulky material from collecting expeditions. 
The sorting tables in the two smaller tank rooms will 
no doubt be more frequently used either as shallow 
experimental tanks or as benches upon which smaller 
aquaria can be placed in series and supphed with running 
water. Over a central sorting table of the same nature in 
the middle of the floor of the larger tank room it is 
proposed to erect an apparatus for communicating motion 
by means of the ‘‘ plunger’”’ device or otherwise to the 
water in any aquaria that may be placed below. 
The upper floor (see fig. 3), which may be entered 
either from the students’ laboratory of the old building, or 
from an outside flight of concrete steps leading to a door 
at the south end, is divided by wooden partitions into a 
central passage and a series of eight separate research 
rooms. Each research room has two windows, about 
thirteen feet of working bench and a sink supphed with 
both fresh and salt water. The intention is that each 
such workroom should be assigned to one researcher who 
is working alone, but there is obviously abundance of 
room for two senior students working in company, or for 
a pair of collaborators engaged in the same research. 
The addition of this research wing has enabled us to 
effect a much-needed improvement in the library on the 
ground floor of the old building. The former dark room 
and store-room, which were only separated off by wooden 
partitions, have been thrown into the library, and the
