genus Emberiza. Dr Mehlis, from Clausthal, spoke concerning a supposed 

 new genus of Mouse found in the Hartz, and described the internal 

 organization of different intestinal worms. Professor Jacobson, of Copen- 

 hagen, made some remarks on the kidney. Roding of Hamburgh exhibited 

 afoetus of the Halmaturus gig anteus, on which several members mftde remarks. 

 Professor Oken, of Munich, exhibited a portion of Wagler's work on the 

 Amphibia, which gave rise to a discussion on the fossil Pterodactylus. 

 Professor Tiedemann, of Heidelberg, exhibited a living Scolopendra morsitans 

 from Brazil, and Professor Fischer, his work on the Oryctography of the 

 Govei-nmmt of Moscow, 1830. Counsellor Schleep, from Sleswig, was 

 appointed president for the ensuing sitting. 



Second Sitting 21st September. The secretary made several commu- 

 nications. Dr Bergman, from Hildesheim, exhibited drawings explanatory 

 of the internal structure of the human brain. Dr Wiedeman, of Kiel, 

 exhibited drawings of the species of the genus Mydas, and distributed copies 

 of his treatise on the genus Achias. Professor Jarocki, of Warsaw, read a 

 paper on the Aurochs, (Bos Urus.) (Seep. 105, supra.) Counsellor 

 Schleep made some remarks on the position of the eyes in the Pleuronectes. 

 Professor Tiedemann detailed the result of his observations on the regenera- 

 tion of nerves. Dr von Chamisso, from Berlin, gave an account of the 

 investigations of Ehrenberg, on the organization of the Infusoria. (See 

 p. 112, supra.) Dr Hineman, of Brunswick, exhibited several anatomical 

 preparations in wax. Professor Oken exhibited some plates from Agassiz' 

 work on fishes. Professor Jacobson was named president of the third 

 sitting. 



Third Sitting. — 22d September. Dr Zincken Sommer, from Brunswick, 

 read a treatise on the " advantage of feeding the caterpillar or the silk- 

 worm with twigs instead of leaves, as usually practised." Professor 

 Huschke, from Jena, spoke on the mode of development of the eye and 

 ear in the chick, and other animals of the higher classes. Professor Otto, 

 from Breslau, made some remarks on malformations of the brain and head, 

 and exhibited drawings of some rare malformations in the mammalia ; at the 

 same time he gave some notices on the anatomy of the genus Pseudopus. 

 Professor Jacobson spoke concerning the so called egg in the gills of the 

 Anodon, which he considered to be a parasitical animal. ( This matter caused 

 considerable discussion, in which Mr Gray of London took a large part, 

 being rather difficmt to convince. We believe, however, that he at length 

 gave in to the general persuasion that Dr Jacobson was right. ) Dr Traill of 

 Liverpool was named president for the following sitting. 



This last notice, we believe, is not quite correct, though it so stands in 

 the report of the secretary. Mr Gray, as coming from London, was named, 

 but owing to a mistake concerning the place of meeting, he did not arrive 

 till at least half an hour after the business had commenced. In his absence, 

 therefore, Dr Traill was requested to take the chair, which he retained. 



Want of room obliges us to defer the remaining three days' proceedings, 

 till our next Number.
