Ehrenberg's Infusoria. — In making a recent communication to 

 the Academy of Sciences respecting the double nature of the organs 

 of generation in the infusoria, M, de Humboldt announced that the 

 great work of this author, on that singular class of animals, is very 

 nearly completed, and will be published in a short time. It will 

 contain engravings of 492 of the polygastric infusoria, and 163 of 

 the rotiferse, from drawings made by M. Ehrenberg.

 plates, on which " at least fifty skulls will be represented, with such 

 national, individual, and anatomical illustrations, as can be obtained

 followed by an exposition of the probable origin of the American 

 tribes."
