Scientific Books in hand, or in the Press. 
Mr. Donovan has now in the Press an Essay on the Origin, Pro- 
gress, and present State of Galvanism, It is divided into three parts. 
The first part contains a sketch of the History of Galvanism, divided 
into four periods; the second, investigations experimental and specu- 
lative of the principal hypotheses ; viz. of those of Volta, Fabroni, 
and of the British Philosophers; of the hypothesis of electro-chemical 
affinity, as maintained by Davy and Berzelius ; and of the identity of 
the agent in galvanic and electric phenomena. The third part con- 
tains a statement of a new Theory of Galvanism ; and is divided into 
two chapters. 
In this theory, the agency of an electric or a galvanic fluid is not 
admitted; the phenomena are conceived to be explicable by the mere 
operation of chemical affinity.
