tain simple apparatus, so that the naturalist on his arrival 
may find at once what he requires for his studies, and can 
directly set to work ; and further, finds a very considerable 
library of zoological works, which is especially rich in the 
department of embryology. This was for a large part Dr. 
Dohrn’s private library, but by presents from authors and 
publishers it has now become a very important library, 
numbering about three thousand volumes, but being com- 
paratively very recent it is not a matter of surprise that 
with systematical works it is but very poorly supplied, but in 
time, by gifts and purchases, it will no doubt possess the 
most important for determining the fauna and flora occurr- 
ing here. I should stronglyadvise any naturalist who intends 
to study to previously obtain the catalogue, that he may 
know what books that he is in the habit of using he had 
better bring with him. 
Another very important feature is collecting and preserv- 
ing the animals brought, so that there is a stock of cer- 
tain animals in alcohol always ready for anyone who may re- 
quire it, and supplies are constantly being sent to all parts of 
Europe to those who require the material for study, and are 
sent at about cost price. At the present moment there is an 
application from a neighbouring Literary and Philosophical 
Society for a supply of Amphioscus in various preservative 
solutions. A few animals have been determined by special- 
ists who have worked here, and this will form a nucleus of 
a museum of the fauna and flora of the Bay of Naples. The 
specimens as yet determined in this manner are too few to 
have much importance, but when the collection is more 
considerable it will be very useful, as any one sending for 
specific specimens can feel more security in the determina- 
tion when this is necessary. 
Besides the knowledge of the fauna and flora, which can 
be gained by the material brought daily by the fishermen, 
those who are working here have the opportunity from
