Some of our correspondents have recently urged the neces- 

 sity of founding our knowledge of the processes of Nature 

 on an acquaintance with chemistry. It may be, that this 

 little volume may avail those who, under a conviction of the 

 truth of this statement, are endeavouring to attain a know- 

 ledge of this science. We copy the list of the book's 

 contents, that they may judge: — "Remarks on the new 

 nomenclature; theory of definite proportions; definition of 

 gases, and method of preparing them ; experiments, sys- 

 tematically arranged, illustrative of chemical science." These 

 experiments occupy sixty-four pages. " Tests for the detec- 

 tion of metalHc poisons ; mineral waters and their contents ; 

 nomenclature : vocabulary of technical terms ; tests, or re- 

 agents required in chemical analysis ; chemical apparatus 

 requisite ; descriptive list of some particular apparatus." 

 The author thus speaks of his own work : — "It is presumed 

 that the following pages may encourage the growth of che- 

 mical knowledge in the tyro of its science. Experiment is an 

 inviting field, and chemistry is a science of experiment. The 

 time is now past for speculation and hypothesis either to 



claim or receive attention This manual has been written 



with a view to invite the student of nature to a very lovely, 

 interesting, and useful branch of knowledge, by softening 

 down the asperities and difficulties of chemical research ; 

 and it is hoped the end in view may be accomplished."
