the publicationa he was preparing by the state of his health, which 

 obliges him temporarily to seek a milder climate. Rosanoff, said to 

 be a young man of great promise just appointed to the place of 

 physiological head botanist, is the author of some morphological and 

 development papers. Famintzin and Baranetzki have published, 

 in the Bulletin of the Academy, papers on the development of 

 gonidia in Lichens, in which they notice the formation of zoospores 

 within the gonidia in genera standing so wide apart in the system 

 that they expect to meet with similar results in other lichens. 

 They have also observed the transformation of these gonidia into 

 bodies heretofore supposed to belong to the freshwater unicellular 

 Algse — a transformation also observed by Dr. Itzigsohn. These pa- 

 pers of Messrs. Famintzin and Baranetzki, as well as others by 

 M. Famintzin, on the action of light on various Mosses and Algae, 

 and on the coloration of leaves, have been more or less reproduced 

 in the Botanische Zeitung, and in the Annales des Sciences Natu- 

 relles. M. A. Fischer v. "VValdheim has inserted, in the Moscow 

 Bulletin, a detailed paper on the spores of Ustilaginese.

 M. F. B. L. Pollen, since his return from Madagascar, whither he 

 was accompanied by M. van Dam, has devoted a considerable por- 

 tion of his time and means to the investigation of the natural his- 

 tory of that island, and is now directing his attention particularly to 

 the Lemuridae, which seem there to have their headquarters. He 

 has, however, published only a first part of his ' Contributions a 

 I'Histoire Naturelle des Lemurieus,' in the largest folio. This first 

 part consists only of a single plate with a life-size figure of a species 

 of Microcebus, with a descriptive text. M, Pollen is also preparing 

 an account of his expedition, accompanied by " Eecherches sur la 

 Faune du Madagascar et de ses dependances," in which he is as- 

 sisted by some of the first zoologists of Holland and Belgium. 

 Already two parts, relating to Mammalia and Birds, by Schlegel, 

 have appeared. Professor Schlegel's ' Revue critique et methodique 

 du Museum des Pays-Bas ' has been continued ; and the same distin- 

 guished zoologist has produced three parts of a work on the Birds 

 of Netherlands-India (Vogel van Nederlandsch Indie) containing 

 admirable monographic revisions, illustrated with fine plates of sepa- 

 rate groups of Dutch- Indian birds. Dr. Bleeker has completed his 

 great * Atlas Ichthyologique dea Indes Orientales Neerlandaises ; ' 

 and Dr. Snellen v. YoUenhoven has issued the third part of his
