QUARTERLY CHRONICLE OF MICROSCOPICAL 
SCIENCE. 
Histology. Glands. — The Structure of the Pancreas. 
M. Gianuzzi, in a paper communicated to the French 
Academy, states that the excretory ducts of the pancreas are 
lined with a very delicate epithelium. Their finer ramifica- 
tions form a network devoid of epithelium, which encloses 
the pancreatic cells in its meshes, and may be compared to 
the biliary network of Hering. The injections by which the 
structure of the pancreas were determined by M. Gianuzzi 
were made by the pressure apparatus of Ludwig. 
The Connective Tissue of Glands. By Franz Boll. One 
plate. Schultze’s Archie. Bd. Y, prt. 3. 
On the Alteration of Tissues in the Inflamed Liver By 
Dr. And v. Huttenbreuner. One plate. Ibid. 
Nerve. — Studies on the Structure of the Cerebral Cortical 
Substance. By Dr. Rudolf Arndt. Third part. One plate. 
Schultze’s Archiv. Bd. V ; prt. 3. 
The Axis-cylinder-prolongation of the Nerve-cells in the 
Cerebellum of the Calf. By Dr. A. KoschennikofF, of 
Moscow. Ibid. 
The Axis-cylinder-prolongation of Nerve-cells in the 
Cerebral Cortical Substance. By Dr. A. KoschennikofF.

Blood. — The Cause of the Formation of the Rouleaux of 
Blood Corpuscles. By Dr. Norris, of Birmingham. Proc. 
Royal Soc., June, 1869. By ingenious experiments Dr. 
Norris shows the cause of the curious agglomeration to be 
due to the fact that the substance of the corpuscle is not 
miscible with water. Gelatine discs wetted and sunk in 
paraffin completely imitated the action of the corpuscles. 
Tegument. — On Cuticular Growths and the Cornification 
of Epithelial Cells in the Vertebrata. By Franz E. Schulze. 
Schultze’s Archiv. Bd. Y ; prt. 3. Two plates. 
Muscle. — Histological Researches on the Lower Animals. 
Koll. and Sieb. Zeitschrift. 1869, prt. 2. By Dr. Fritz 
Ratzel, of Carlsrhue. Two plates. This first instalment of 
a series of papers treats of the muscular tissue of the 
Oligochceta.
