kind that can most readily be obtained—is thrown in to 
them once a day. Some of the lobsters have now been 
in for three years and have spawned twice in that time. 
This vivarium at Brodick, however, is only used as a 
breeding pond, and a protection to the mother lobster and 
the spawn until hatching takes place. No attempt has 
been made to retain the young larval lobsters when set 
free and rear them up to the adult condition. 
When I visited this vivarium the water was run off at 
low tide so as to let me examine the interior. It then 
contained a number of large lobsters, both male and 
female ; some of the latter had spawn which was ready to 
hatch out, and in fact some of it had been hatched since 
the previous day, others had spawn which had just 
recently been produced, and all seemed in a thoroughly 
healthy and satisfactory condition. 
I have been of opinion for the last few years that Port 
Erin in the Isle of Man would be a most suitable place 
for lobster culture. In the first place, there is pure sea- 
water, and a rocky coast with abundance of sea-weeds ; 
and moreover lobsters live already in the neighbourhood, 
showing that the ground and other conditions are suit- 
able, and ensuring a ready supply of the parent animals. 
Secondly, on the north side of the bay, between ‘the 
Biological Station and Bradda Head, there are several deep 
creeks in the rocks which could be easily closed in to form 
vivaria. Thirdly, the lobsters could be easily fed and 
looked after by those having charge of the Biological 
Station, and the Sea-Fish hatchery, when that is estab- 
lished. Fourthly, the lobsters, whether full-grown ones 
for the market or in their younger stages for stocking 
other grounds, could readily be sent off from Port Erin, 
by train to Douglas and then by steamer to Liverpool, 
Fleetwood, etc., or direct by steamer from Port St. Mary
