Zeitschrift fiir Anatomie und Entwickelungsgeschichte, von W. His 
und W. Braune, Band 2, 3rd and 4th Heft. Leipzig, 1876.—A good 
paper is that on the Architecture of Bone Tissue, illustrated by a 
plate, by Dr. Karl Schulin. In this the author tries to show how the 
bone structure between the Haversian canals is arranged. He sup- 
poses a certain plan which would give the greatest amount of power 
of resistance to the bones, and he endeavours to show that this is 
carried out in the structure of certain bones, especially of the skull.— 
A paper on “The Aqueductus Vestibuli of Man and of Phyllodactylus 
Europeus,” by Professor Dr. Riidinger, of Munich, is for the most 
part purely anatomical in the coarser sense of the word. Still the 
author refers to the microscopical characters of the lining epithelium, 
so that it deserves mention.—A very valuable contribution is that by 
Herr G. Schwalbe, “On the Structure of Elastic Connective Tissue,” 
illustrated by a beautifully delineated plate. This paper deals ex- 
haustively with the subject, extending as it does to nearly forty pages. 
The chief fact of importance is that relating to some of the fibres, 
which it would seem have a peculiar structure, which appears to endow 
them with elasticity. There seems to be a division of the fibre 
transversely into a series of particles, with lens-shaped spaces between 
them, and it is possibly in this way that their elasticity is provided.— 
The Structure of the Hair-glands (sebaceous) and their Muscles is a 
good paper by Herr Dr. F. Hesse, Prosector at Leipzig. This is of 
interest simply from the fact that the author describes minutely 
(from a magnifying power of 600 diameters) the structure of the 
peculiar muscles which are connected with the hair-sac. He dwells 
at some length on the researches, published in 1875, of W. Stirling.— 
On Bone Lymph Canals is a brief note by Dr. A. Budge, of Greifs- 
wald. 
Archives de Zoologie Expérimentale. Fdited by H. de Lacaze- 
Duthiers, Année 1876, No. 2.—This number contains a series of 
valuable papers :—“ On the Development of Mollusks,” second paper, 
by M. H. Fol, deals with the He‘eropoda; “On a Species of 
Infusoria Parasitic on Fresh-water Fishes,’ by M. Fouquet; and 
“On the Organs of Sense in the Actiniz,’ by M. Korotneff, which is 
illustrated by a splendid series of drawings, which we commend to 
Dr. Duncan’s notice. The notes and reviews are also of microscopical 
interest, more especially that on the development of Holathuriade, 
which is by M. E. Selenka.
