Elements of Practical Chemistry,' Comprising a Series of Experiments 

 in every Department of Chemistry, fyc. By David Boswell 

 Reid, Experimental Assistant to Professor Hope, fyc. &;c. 



THIS work is presented to the chemical student under circum- 

 stances calculated to raise high expectations of its value. 

 Mr. Reid was formerly the pupil, and is now the chemical assistant, 

 of Dr. Hope, — a lecturer, who is justly celebrated for the excellence 

 and accuracy of his experimental illustrations : to him the book is 

 dedicated, and we may, perhaps, not unfairly presume that it did 

 not make its appearance entirely without his sanction. 



Thus advantageously situated, Mr, Reid must excuse us, if we 

 examine his pretensions, which are by no means slight, with some 

 degree of minuteness. " The object of this work," says the author, 

 " is to present the student with a systematic series of experiments, 

 sufficiently broad to lay a proper foundation for acquiring habits of 

 practical skill in chemical operations, with precise and minute direc- 

 tions for enabling him to perform them." 



We shall not pay any attention to Mr. Reid's arrangement, nor 

 proceed regularly through the work, but confine our remarks prin- 

 cipally to the chapter on Nitric Acid. The subject is one of iroport-
