cumstances most favourable to the development of the myriads 
of oscillatorise which redden the waters. Haller, and a preced- 
ing author, have already mentioned a conferva, which they dis- 
tinguish by the same character, and which is perhaps identical 
with the oscillatoria of which we are speaking. M. Colladon of 
Geneva read a memoir, containing the results obtained from the 
chemical analysis of this substance. It was conducted by MM. 
Colladon, Peschier and Macaire, and agrees with the microsco- 
pical observations of MM. De Candolle, Vaucher and Prevost, 
in shewing that the substance in question is an oscillatoria. 
This analysis has discovered the following materials in its com- 
position. A red colouring matter, partly soluble in alcohol. 
2d, Chlorophylle. 3d, Gelatine in considerable quantity. 4 th 9 
Albumen. 5th , Some earthy and alkaline salts, and a little ox- 
ide of iron. These results confirm the opinion of some natura- 
lists respecting the products of animal nature which are met with 
in a great number of mineral waters, and give support to the ob- 
servations made by Vauquelin, upon the green substance of the 
waters of Vichy, in which he found a substance that had much 
resemblance to albumen. — Bibliotheque Univers. August 1825.

42. Discovery of the Anaplotherium commune in the Isle of 
Wight. — The identity of the fresh- water formations of the Isle of 
Wight, with those in the vicinity of Paris, has been clearly esta- 
blished, since the publication of Mr Webster’s excellent memoirs 
on the former ; and this conclusion has rested upon the simi- 
larity of the remains of fresh water mollusca and vegetables which 
these respective formations contain, and on the correspondence 
in their substance, and their relative position to other strata of 
marine origin, quite sufficient to place the contemporaneous de- 
position of these remarkable strata out of doubt. There still re- 
mained a point, however, on which evidence seemed desirable, 
inasmuch as the remains of the large quadrupeds which occur 
in the basin of Paris, had not been ascertained to exist in Eng- 
land. This desideratum has been in some measure supplied, by 
Professor Buckland * having lately discovered in the collection 
Annals of Philosophy for November 18 25 .
