FLANNEL FORMED OF INFUSORIA AND CONFERVJE. 



On the 17th of October last, Professor Ehrenberg laid before the 

 Academy of Sciences of Berlin, a foot and a half square of natural 

 wadding or flannel, consisting of Infusoria and Confervcd, which was 

 found to the extent of several hundred square feet near Sabor in 

 Silesia, after an inundation. We have already had occasion in pre- 

 ceding numbers of this Journal, to lay before our readers Professor 

 Ehrenberg's notice respecting the animal and vegetable nature of the 

 meteoric paper of 1686, (See Annals, vol. iii. pp. 185 and 320,) and also 

 the communication of Ehrenberg and Kersten respecting the natural 

 leather of Freiberg, to which the present substance is analogous, but 

 far more surprising from its occurrence in such an immense mass. The 

 flannel is chiefly formed of unramified branches of Conferva rivularis 

 interwoven with fifteen species of Infusoria and some shells of the 

 water-flea {Daphnia). Of the Infusoria eleven belong to the family 

 of the Baccillarice, and of these six to siliceous -loricated genera ; 

 several Closterina, &c. Predominating are the Fragillaria, Navicula 

 viridis, and Cryptomonas lenticularis ? All the forms are known 

 species. — Berichte der Akademie, Oct. 17, 1839.
