 doubter. A searcher after ali truth. I also procured and read ali that 

 1 could find on Brownonian motion. That motion which particles of 

 any kind of matter moves by itself when suspended in water. I saw 

 that the motion vvas not physical alone, or at least physical distin- 

 guished from vital, what ever that may be. 



And now I shall detail what 1 saw everywhere. 



When viewed by means of a I-4 th there is seen a mass of green 

 plants that are algae. It is Lyngbya muralis, C. A. A. Systema Al- 

 garum, 1824. This is Conferva valutino., Bory. Mem., Conferva mu- 

 ralis, Dillw. t. 7, Roth, E. B. t. 1554, Dyssus botryoides, Gir. Ch. 

 n. 22, Byssus vehdina, Gir. Ch. n. 1, Weiss. Oscillatoria parietinq, 

 Vauch. t. i5, f. 8, Conferva Fluggii, Roth? and Oscillatoria muralis, 

 Ag. Jurg. 5, ó, Lyngb. Moug. & N n. 597, Hook, this is according 

 to Agardh. It is describcd by Hassall in his History of the British 

 Freshwater Algae, pag. 221 and figured in his Piate LIX, fìg. 7, 

 He says it is « On the ground in ali damp situations early in the 

 spring, » He says « This a very distinct species, rendered interesting 

 from the peculiarity of its habit » 1. W. Grifjìth and Arthur Henfrey 

 says in The Micrographfc Dictionary for 1 856 when speaking of 

 Lyngbya, Ag. » a genus of Oscillatoriaceae (Confervoid Algae) related 

 to Calotlirix and Oscillatoria, distinguished from the former by its 

 strati fied habit. from the later by the long filaments. «And says» 

 L. muralis grows in damp places and in water, pag. 409, Rabenhorst 

 in his Flora Europea Algarum aquae dulcis et submarinae, 1868 is 

 disposcd to place it in Ulothrix of Kutzing, and describes it as Ulo- 

 thrix radicans, Ktz. 1 think we can cali it Lyngbya muralis, C. A. A. 

 as Hassall gives a good figure of it. I saw it die as a Lyngbya mu- 

 ralis and I saw it grew into a Spyrogyra several times. I also saw 

 it grow into a Cladopìwra, or at least it looks more like that than 

 any other fresh water alga. 



But it is not these algae that I wish to detail now. It is the 

 origin of Protista, Bacillaria that I wish to speak of. 



There is present a lot of sand, or earth it seem to be. The 

 particles are very minute. They are so small that I cannot measure 

 them. And therefore I cannot analyse them also. But they seem to 

 be clayey matter. They are mostly quiet, that is to say they do not 



move. Some of them move slowly. These are the same in appea-
