WILLIAM GREGORY, M.D., 



PROFESSOR OF CHEMISTRY IN KING'S COLLEGE, ABERDEEN. 



Extract from Dr. Gregory's Preface. 



" In offering to the British Public the Seventh Edition of Professor Turner's 

 Elements of Chemistrj', the Editor feels it quite unnecessary to advance any thing 

 in recommendation of a work so firmly established in the public favour. The death 

 of its lamented Author has thrown into other hands the task of rendering the 

 Elements of Chemistry equal to the demands made upon such a treatise by the 

 rapid and unceasing progress of discovery, — of giving, in short, to the student, a 

 compendious view of the actual state and prospects of the science. 



" When the Sixth Edition was projected, in the life-tiine of the Author, it was 

 arranged that Professor Liebig should undertake the department of organic 

 chemistry, while Dr. Turner himself was to re-write the inorganic chemistry, that 

 being the department with which he was more especially familiar. The choice of 

 Professor Liebig has been ratified by the unanimous voice of European chemists, 

 by whom he is admitted to be the first living authority in organic chemistry. 



" The delay which has occurred in the completion of that edition, which will be 

 finished along with the present, has been chiefly owing to the wish of Professor 

 Liebig ':o render it what it professes to be, — namely, a durable record of well- 

 established facts. 3Iany laborious series of experiments have been completed in 

 his laboratory with this object alone in view, and many are now in progress. The 

 results of these will be embodied in both editions, which will thus constitute the 

 first tolerably complete account of organic chemistry in the English language. In 

 both will be found the latest and most accurate information, as far as it had come 

 into the hands of the English Editor when the respective sheets were written or 

 revised. For examples of the great additional value thus given to the work, the 

 reader is referred to the sections on alcohol, and the others, on sugar, on benzulc, 

 on the vegetable acids, and on the oily acids and fixod oils. 



" Much yet remains to be done, before the boundless field of organic chemistry 

 shall be thoroughly explored ; but the Editor ventures to entertain the hope, that 

 the present work, by making the rising generation of British chemists aware of what 

 their brethren on the Continent have done in this department, may contribute to 

 induce them to cultivate organic chemistry, and thus secure for their country a 

 share of the honour of those discoveries which will infallibly be made in this 

 division of their science. So rich, indeed, is the vein of discovery in this mine of 

 research, too long neglected among us, that, in tlie words of Professor Liebig, ' we 

 have only to stoop down in order to pick up discoveries from the ground.' It need 

 hardly be added, that to succeed in this, we must proceed on the only true method, 

 the Baconian, that is, rigid induction from facts accurately observed."
