eldest boy (Torillo) when I was there had devoted himself 
diligently to increasing his knowledge, and was able to give 
valuable assistance, and I see he has had more important 
duties assigned to him, and Dr. Dohrn speaks of the increas- 
ing knowledge of the other boys. 
The first volume of Mittheil ungen contains several valu- 
able papers. The continuous observations of Mr. Schmidtlein 
on the habits of the animals in the Aquarium bring out 
much that is interesting, and such observations are much 
needed in all aquaria. Dr. Dohrn discusses the zoological 
position of the Pycnogonidae. Dr. P. Mayer has in each 
part a ps.per on Carcinological studies, and in the second he 
follows up Mr. Bullar s investigations on the Isopoda, and 
supports most of his conclusions, showing the curious 
hermaphroditism of the group, the young being active males, 
while as they grow older most of the male organs wholly or 
partially disappear, in connection with which the female 
organs are then developed. Dr. Falkenberg gives a synopsis 
of the fucoids of the bay of Naples. 
Most but not all of the papers in these two parts are by 
the staff, but the number of papers giving the result of 
studies made in the Station by naturalists is now very con- 
siderable, and is spread over the periodical literature of all 
scientific Europe. 
As the institution now lays itself out more and more for 
supplying material to naturalists, prepared according to their 
instructions, the list with prices which is given at the end 
of the second part, will be of service to anyone requiring 
such aid. 
This is much the largest zoological station, and may be 
looked upon as to a great extent the parent of others now 
springing up in many directions. Quite recently the Triest 
zoological station has also published three parts of a volume, 
containing a series of most valuable results attained there. 
There is also the station at RoscofF, which supplies the 
“Archives de zoologie experimentale” of M. Lacaze-Duthiers 
with many important papers. There is a more or less per- 
manent station on one of the islands near Denmark, and it
