M. BioT, On the Constitution of the higher Regions of the Earth's At- 

 mosphere. (From the Comptes ReJidus des Heanccs de VJcadimie des 

 Sciences.) 



Prof. Ehrenberg, On Fossil Infusoria. — The two Memoirs entire, with 

 an Engraving of the Figures. (From PoggendorfF's Annalen.) 



M. Becquerel, On the artificial production of Crystallized Minerals by 

 Voltaic action. 



Prof. H. Rose, On a New Combination of Anhydrous Sulphuric and Sul- 

 phurous Acids. (From Poggendorff's Annalen.) 



M. MossoTTi, On the Forces which regulate the Internal Constitution of 

 Bodies. (A Memoir published separately; containing the views re- 

 specting the identity of origin of gravitation, the attraction of aggre- 

 gation, and electrical attraction, involving the discovery of the physical 

 cause of gravitation, which were explained, from this Memoir, by Mr. 

 Faraday at the first evening meeting of the Royal Institution for the 

 present season, January 20, 1837.) 



M. Pelouze, On certain Combinations of a new Acid, formed of Azote, 

 Sulphur, and Oxygen. (From the Annales de Chimie et de Physique,) 



Baron von Wrede, On the Absorption of Light, according to the Theory 

 of Undulations. (From PoggendorfF's Annalen.) 



My connexions and my profession may afford me, perhaps, 

 advantages for carrying on the work with a less amount of 

 support than would be requisite if it were in other hands. 

 I cannot, however, be expected to incur a considerable loss ; 

 and I look with confidence to those who approve my attempt 

 to give me their active aid. If they wish the work to be con- 

 tinued, they will, I trust, exert themselves to increase the 

 number of purchasers, which at present is far below what is 

 absolutely necessary. 



I have only to add, that the attention requisite for conduct- 

 ing this work I shall be happy to give, if its circulation can 

 be so far extended as barely to pay the cost ; and, though 

 necessarily it can hardly be of a popular character, this is 

 not a greater degree of success than may be hoped for, in this 

 country and its dependencies. Richard Taylor. 



XIX. Experimental liesearchcs ofi the Nature and Pro- 

 perties of Albumen, SfC. By Golding Bird, Esq., F.L.S., 

 F.G.S., Lecturer on Experimental Philosophy at Gui/s Ho- 

 spital, 



[Continued fi'oni vol. ix. p. 115, and concluded.] 



N the former part of this communication I pointed out the 

 solubility of albumen after its coagulation by alcohol, &c., 

 in water saturated with carbonic acid, as well as the curious 

 fact of that acid decomposing the alkaline albuminates, causing 

 the separation and consequent precipitation of the albumen in 

 an insoluble form, capable of being redissolved by an excess 

 of the acid. I also mentioned some circumstances connected 

 with the action of coagulated albumen on the carbonates oi
