the Bound Brook Park, Newark, New Jersey last summer the follo- 

 wing. About two weeks ago, when it was dry, it was immersed in 

 water and left to grow. It grew and on the sides of the bottle there 

 was a deposit. I examined it to see what tt was?Ifound to be an 

 Amphora and can not identify it with certainty, but it is an Am- 

 plio ra. It is perhaps Amphora ellìptica, C. A. A. 1824, Syst. p. 3 11, 

 This is Amphora? cìliptica, F. T. K. 1844, B a c > pag. 108, Taf. 5, 

 fig. XXXI. There was nothing in the sediment of the bottle, but 

 when it was put in the sun bubbies of oxygen appeared and it see- 

 med to grow. I now make Amphora ovalis, Bac. 1844, pag. io et 

 Taf. 5, fig. XXXV et XXXIX, which is Navìcula Amphora, Ehrb.

This is one of the ways Bacillaria are formed and grew from 

 what? There was not clay or other hard material from which the 

 Bacillaria could grow, only dried frustules of Bacillaria and plants 

 which were common. The whole mass was dead, at least it was 

 called dead. 1 gathered it for dead Bacillaria and kept it for makeing 

 a botton in my aquarium. I shall keep it for several years and then 

 immerse it again in water and see what will grow from it. 



I also, just now, examined the mass of sediment that was im- 

 mersed in this bottle of The Bound Brook Park. It was mostly plants 

 and some sancì. There was on the plant some Cocconeis and a Fra- 

 gillaria and others dead. But there was also, livening, some Amphora
