Histology. Nerve. — On the miniate Anatomy of the Pa- 
cinian Corpuscles of Man and other Mammifers. By Dr. G. 
V. Ciaccio, Professor of Physiology at Parma. Turin, 1868. 
4to, 5 plates. — Dr. Ciaccio was, five years ago, studying his- 
tology in this country with Dr. Lionel Beale. At that time 
he published a paper in this Journal; he has, since his return 
to Italy, written some valuable memoirs, one of which, on 
the Structure of the Skin of the Frog, he was good enough 
to send us. The illustrations, both in that and the present 
memoir, are very beautifully executed. This is a very 
detailed account of the Pacinian body, the methods of pre- 
paring the object for examination being first discussed in 
detail. Dr. Ciaccio concludes that the structure of these 
bodies is quite peculiar (he is not able to add much to what 
was previously known on this score, but gives valuable con- 
firmatory evidence), and their function also must be regarded 
as a special one, which is at present unknown.

The Central Nervous System and the Auditory Organ of 
the Cephalopods. By Ph. Owsjannikow and Dr. A. Kowa- 
lewskv, Mem. de V Acad. Imper. des Sc. St. Petersbourg, 
Tome xi, No. 3. — The authors give the microscopic structure 
of the ganglia and the microscopic relations of the nerve- 
fibres in several species of Cephalopoda. The structure of 
the auditory sac itself is elaborately worked out and figured. 
Several plates of double quarto size, and marvellously drawn, 
illustrate this paper. Owsjannikow’s paper on the Lamprey's 
(Petromyzon fluviatilis) ear, in the same series of memoirs, 
furnishes an interesting comparison of the structure in the 
highly organised mollusc and the low-grade fish. 
On the Auditory Organs of Molluscs. By M. Lacaze 
Duthiers. Comptes Rendas, November 2nd, 1868. — This 
paper is one of considerable importance, and one which 
should excite attention of all comparative anatomists. Since 
Siebold, Kolliker, and others drew attention to the otolithic 
sacs of Gasteropods, Levdig, Claparede, Huxley, and Lacazc
