ON A MINUTE NOSTOC WITH SPORES. 



By William Archer. 



The appearance of a highly interesting and noteworthy commu- 

 nication from Professor Max Reess conveying a description of 

 certain novel experiments instituted by him on the growth of a 

 Collema from the spores, and giving his views as to the bearing 

 thereof as regards Nostoc,* which I have only just seen, recalls to 

 my recollection a seemingly remarkable, though isolated example of 

 a not uncommon minute aquatic Nostoc brought forward by me at 

 a recent meeting of our Microscopical Club, but not publicly ex- 

 hibited, from want of time, and since then somehow overlooked to 

 be recorded. I will not attempt on this occasion to give any ac-. 

 count of Reess' views, or those of Schwendener, but will reserve 

 my observations thereon for a future communication to this Journal.
