QUARTERLY CHRONICLE OF MICROSCOPICAL 
SCIENCE. 
GERMANY.—Siebold’s und Kolliker’s Zeitschrift—The 
third part for the year of this most valuable and interesting 
journal has just been received in England, having appeared 
rather late. The first paper it contains is entitled “ Researches 
on the Sclerotic of Fishes,” by Theodore Langhans, and is 
illustrated by two finely executed plates. The paper appears 
to be the result of a most complete and extensive series of 
observations extended through a vast variety of forms of 
fishes. The author treats, in particular, of the histology 
and minute structure of the fibrous capsule of the eye. Doc- 
tors Hermann and Leonard Landois contribute a most valuable 
paper “On the Histological Elements of the Bodies of Insects,” 
in which they point out the distribution of the various 
tissues entering into the composition of the insect’s organism. 
Elias Mecznikow sends some “‘ Contributions to the Knowledge 
of the Chetopods,” which are of some interest. The genera 
which he particularly makes the subjects of his remarks, are 
Fabricia, Syllis, and Spzerodorum, and also a new genus and 
species, Microphthalmus Sezelkowii, which he describes; two 
plates accompany this paper. Perhaps that which will most 
interest the readers of our Journal is the last, by Dr. Ernst 
Hockell, “ On the Sarcode-bodies of the Rhizopods.” Dr. Hockell 
gives a very masterly exposition of the views now entertained 
with regard to ‘“sarcode,” and advances his own opinion on 
the question. The nature of sarcode, and its modifications 
in the various parts and in various forms of the Protozoa, is set 
forth in twenty-one concise statements, which are remarked 
upon in succeeding pages. A coloured plate, well executed, 
illustrates this paper. 
Muller’s Archiv-—No issue of this journal has been received 
by us since February, 1865. 
Max Schultze’s Archiv —The second number of this journal, 
which was so well inaugurated last May, has not yet appeared.
