The author's observations support the conclusion that the motor 

 spinal nerves of Lepidosiren first appear as strands of soft granular 

 protoplasm, extending between the spinal cord and the myotome. 

 These strands are not cellular. They later become fibrillated and in- 

 vested by mesenchymatous sheaths. c. J. ii. 



Coggi, Alessandro. Le ampolle di Lorenzini nei Gymnofioni. JMonitorc 

 Zoologico Italiano, 15, No. 24g-j6. 



On the basis of the figures and descriptions of the vSarasins, 

 the author compares the ^' Nchcuolircu,^' or accessory lateral line organs 

 on the head of Ichthyophis with the ampullae of Lorenzini of elasmo- 

 branchs, concluding that the organs are strictly homologous, thus 

 strengthening the current belief in the archaic character of the Gynmo- 

 phiona. 



It will be recalled that the reviewer has suggested (this Journal, 

 vol. 13, p. 135) a similar homology between the ampullae of Loren- 

 zini and a type of "small pit organs" found in the skin of the North 

 American siluroid fishes, though the evidence for this relationship is 

 not regarded as conclusive c. j. h. 



Freidenfelt. T. Ueber den feineren Bau des Visceralganglions von Anodonla. 

 Lituds Universitets Arsskrift, Bd, 40, Afd. 2. Nr. 5. Lund, 1905. 



A detailed description of the neurones of the visceral ganglion 

 and their connections, after methylene blue preparations, illustrated by 

 four good plates. The author finds no true net-work (protoplasmic 

 continuity of the older authors) in the neuropil, but refrains from ex- 

 pressing an opinion on the question of continuity of the neuro-fibrils of 

 Apathy and Bethe. c j. h. 



Tumors of the Cerebellum. 



Under the above title, the A. R. Elliott publishing Co., of New 

 York, has re-printed six papers by Drs. jNIills, Frazier, de Schwein- 

 ITZ, Weisenburg and Lodholz. While the clinical and surgical details 

 do not fall within our limits, we call attention to the cases reported and 

 to the summaries of literature as important contributions to the theory 

 of cerebellar functions. c. j. h.

A brief statement of a remarkable case of cerebral malformation 

 where the mental life seemed perfectly normal. An extended account 

 of the case will shortly appear in the Archivio Italiano di Anatomia e 

 di Embriologia j. c. b
