Bosphorus, which were transmitted by Koch from Con- 

 stantinople. (Ib. 1843, p. 253.) All the new genera and 

 species found on this occasion have been incorporated by 

 Ehrenberg in his system. 



Werneck (Archiv, 1843, Th. i, p. 105) has expressed him- 

 self on the subject of GaUionella and Monadbia in the 

 ferruginous bog-water, to whose observations Ehrenberg has 

 also added various remarks. (Archiv, 1843, Th. i, p. 105). 



Kiitzing (Anat. Physiol. u. Systemkunde der Tange, 

 1843, p. 4) has referred the Bacillarias to the Algre as 

 Diatomese. According to him, they would seern to enjoy a 

 vegetable as well as an animal life. These Diatomese we 

 find described and figured in a great work by Kiitzing, ac- 

 cording to genera and species, with short diagnoses. (Die 

 kieselschaligen Bacillarien oder Diatomeen, 1844.) He has 

 nevertheless, however, excluded GaUionella ferrug'me a, Ehrb., 

 from the Diatomese as a true Conferva, having endeavoured to 

 show (ib. p. 56) that it takes no part, as Ehrenberg thinks, 

 in the formation of the iron-ochre and meadow-iron ore, but 

 that the carbonate of iron contained in ferruginous springs, 

 is decomposed, and, becoming oxide of iron, is deposited as 

 the so-termed iron-ochre, whether GaUionella ftrruyinea, 

 which, moreover, is not even furnished with a siliceous case, 

 be contained in the water or not. Kiitzing also holds the 

 tenet, that it is only in the higher organic world that a 

 vegetable and animal life are to be contradistinguished, and 

 that in manv forms of the lower creations this distinction 



if 



does not exist. In this sense he has written a paper (Ueber 

 die Verwandlung der Infusorien in niedere Algenforrnen, 

 1844), in which the proposition is started, that the Infuso- 

 rium Enchelys pulvisculus, is transformed into a Protococcus, 

 and finally into an Oscillatoria ; and further, that the Infu- 

 sorium Chlamidomonas pulvisculus is metamorphosed into the 

 Conferva, Styyeoclonium, together with which, Tdraspora 

 lubrica, or yelatinosa, Palmella botryoides, various species of 

 Protococcus and Gyges } are represented as different forms of 

 development. Flotow also (Nov. Act. Acad. nat. Curios.
