[Gives an account of two series of experiments : (1) witlt low temperatures, 

 (2) with sea- water. From the first series the author concludes that low tem- 

 peratures act upon the vegetative growth of this alga with the same result 

 as do high osmotic pressure and poison cations. As to the second, filaments 

 placed in undiluted sea-water take the typical Fahwlla form, as in other 

 solutions of high pressure. Zoospores are not produced, nor do those 

 previously produced germinate.
