“ Observations on the Innervation of the Intracranial Vessels,” by 
G. C. Huber; “Observations on the Blood Capillaries in the Cere- 
bellar Cortex of Normal, Young, Adult, Domestic Cats,” by F. S. 
Aby; “An Anomaly in the Internal Course of the Trochlear Nerve,” 
by R. Weil ; “Critical Review of Recent Publications of Bethe and 
Nissl,” by A. Meyer; and “ Report of the Association of American 
Anatomists,” by D. S. Lamb. 
We learn from Natural Science that Dr. Gregg Wilson points out 
that the lung of Ceratodus arises in the two-months-old larva as a 
mid-ventral diverticulum, and that the development of the pronephros 
is strikingly like that of urodeles. 
The classification of the Coccidiide is treated by Louis Leger 
(Am. Mus. d Hist. Nat. Marseille, Série 2, Bull. I, 71, 1898), who 
divides this unity of the Sporozoa into three tribes, — Disporocysts, 
Tetrasporocysts, and Polysporocysts,— according to the number of 
spores in a cyst. Analyses of all known species are given, and also a 
synoptical table of genera. A number of new or little known species 
are minutely described and figured ; all of them from arthropods, and 
most of them from myriapods. 
The life and work of Fr. Redi, famed equally as a student of let- 
ters and of science, are the subject of a recent sketch (Arch. Par., 
I, 3, 420, 1898). A facsimile of a handsome copperplate portrait 
and of a medallion, both from the collection of Professor Blanchard, 
accompany the article. It is rather startling to read in the bibliog- 
raphy of observations on parasites, and in the next sentence to see 
listed sonnets and dithyrambics ! 
Dr. H. Wallengren has published in the Siologisches Centralbiatt 
an account of the conjugation of Æpistylis simulans. He finds that 
the microgonidium is not wholly absorbed by the macrogonidium, 
the entoplasm and the nuclei alone being retained, while the shrunken 
ectoplasm is rejected. 
The Palolo worm has been carefully studied from the taxonomic 
standpoint by E. Ehlers (Gottingen Nachrichten, math.-phys. K1., IV, 
1898). He identifies it as Hunice viridis Gr., and finds the formation 
of the palolo to be an instance of epitoke, the first observed in this 
family. The epitokous portions are pelagic and constitute the major 
part of the worm, only 250 somites out of 544, e.g., being atokous. 
The paper includes a full discussion of the structure of both parts.
