REVIEWS, 
Les Annelides Chetopodes du Golfe de Naples. Par Edouard 
Claparede. Geneva. 
Observations Relatives a un ouvrage de M. Claparede. 
Par M. de Quatrefages. 
Professor Claparede’s magnificent quarto volume, with 
its thirty- two beautifully drawn and coloured plates, has been 
expected anxiously by naturalists since the publication of 
the preliminary notice of the work by the author himself, 
which we gave in abstract some months since. That Annelids 
are truly microscopic animals in the sense that they cannot 
be at all studied without the microscope, no one can doubt 
who looks at M. Claparede’s plates. The majority of the 
figures are illustrations of microscopic detail only to be 
observed with the highest powers, but necessary for the 
proper classification and identification of the beautiful crea- 
tures to which they belong, which are depicted beside them 
in true colours, as accurate as they are creditable to M. 
Claparede’s artistic feeling. 
We will not here go again over the ground which we have 
before traced, but allude to some of the matters of interest 
special to this volume. In the first place the work, which is 
the result of six months’ observation during 1866-67, is dedi- 
cated to Armand de Quatrefages, Membre de l’lnstitut, in a 
few elegant phrases which state that M. Claparede intends to 
expose a great number of M. de Quatrefage’s errors, but has 
a great feeling of regard for him and his labours. 
M. de Quatrefages has felt not a little embarrassed by this 
dedication, and has failed to exhibit in his reply to some of 
the attacks that characteristic politeness and elegance, com- 
bined with severe critical power, which we notice in M. 
Claparede’s work. 
M. Claparede is not a Frenchman, although he writes 
some of his works in that language ; and he has no sympathy 
with that curious and, indeed, altogether special, character- 
istic of French biologists, of omitting to refer to the works 
of previous writers on the subject they discuss — unless it be.
