Introduction. 



On the 1st August last year, I received, through the 

 kindness of the well-known French naturalist M. E. Chevreux, 

 2 tubes with dried mud taken by him from 2 different 

 localities in the neighbourhood of Bona, Algeria. The one 

 sample was taken on the 6th July of the same year from the 

 swamp of »Bon Kamera«, the other on the 8th July, from 

 that of »Kharezas«. Each sample was moreover accompanied 

 by some spirit specimens taken from the same localities. 

 Immediately after the receipt of the samples, I arranged 

 a number of aquaria, each to receive small quantities of the 

 mud, and I have been continuing my experiments not only 

 during the remainder of the summer and autumn, but 

 also during the whole winter until the present time, the 

 aquaria having been placed in a room continually heated.
