RECENT WORKS ON THE EMBRYOLOGY OF ARTICULATES. — Besides the 
very valuable paper of Melnikow on the embryology of the lice and other 
insects pester noticed and quoted, we have to enumerate several others 
of great importance, and which we hope to find room to notice at greater 
war hereafter. Professor Claparéde has published a paper, Me illus- 
trated, on the embryology of worms, especially Spirorbis, in Siebold and 
Kolliker's “Journal.” Melnikow writes in gie aneri nans * On 
the early stages of Tenia cucumerina, with a vei figures. Dr. Richard 
Greef publishes in the same number of the ‘‘ Archiv" some most inter- 
esting researches on Hide meines forms of Arthropoda and worm- 
pn SER by four pla 
r. Ant ohrn has Aeg runs the first part of his “Researches 
on vs ioci and Development of Arthropoda" (Insects and Crusta- 
cea) with nine excellent plates. It is extracted from Siebold and Kol- 
liker's ‘“ Journal.” He here records his observations on the embryology 
of Cuma and allied genera, of certain sea spiders (Pycnogonidz), and 
thinks that embryology shows that these curious animals, classified 
y many naturalists with the Ara ie are really Crustacea; and of 
Daphnia, Praniza, and Paranthura Costana. 
A paper of the greatest interest to Mlbonio etia is M. Ganin's ** Con- 
tribution to a Knowledge of Developmental History in Insects" in Sie- 
bold and Kolliker's “Journal.” It is fully illustrated, and some of the em- 
bryoes and larve of certain Pteromali, Platygasters and Polynemas are 
of such startling interest, from their resemblance to the zoeüs of crabs 
and to certain low worms, that we must defer any farther notice for an- 
other number, when we can insert cuts to illustrate our review 
THE BOWDOIN SCIENTIFIC REvIEW.* — Two numbers have appeared of 
this fortnightly paper, which is viciis im Professors Brackett and 
Goodale of Bowdoin College. It is devoted mostly to chemistry and 
physiology, and the editors say in their announcement that ** it was orig- 
inally their design to communicate to their fellow physicians in Maine 
recent intelligence in physiology, and chemistry applied to eee 
This design has not been relinquished, but it has been somewhat moditied 
at the suggestion of many, and the scope of the journal has been Make 
without trespassing upon the field now so well occupied by our American 
journals of natural history, physical science, and medicine. It is believed 
that much of the work now accomplished by many of our domestic 
foreign periodicals may made more directly available by the regular 
journal will approach that of **Cosmos" and ‘‘ Les Mondes," but more 
prominence will be given to the results of English and American study.” 
We trust that this enterprising and ably conducted journal will meet with 
every possible encouragement. We quote the conclusion of M. Mayer's 
*A Fortnightly Review. Brunswick, Maine, 8vo, pp. 32. $2.00 a year.
