240 THE EOYAL INSTITUTION. [CHAP. IV. 



mathematically on the various subjects of the lectures ; it 

 will save considerable pains in consulting other authors, and 

 the most experienced may often find it convenient for occa- 

 sional reference. It was the more desirable that something 

 of this kind should be inserted, as mathematical arguments 

 will be avoided as much as possible in the lectures ; and for 

 this reason the demonstrations which occur in the syllabus 

 are distinguished from the principal text by a smaller type, 

 and a separate place in the page. In a future edition a fifth 

 part will probably be added, containing a catalogue of the 

 best authors, with references to their works upon each 

 subject. One acknowledgment must, however, be inserted 

 here for the extensive use that has been made of the valuable 

 articles contributed by Professor Kobison to the 'Ency- 

 clopedia Britannica.'

The volume forms an octavo of upwards of 250 

 pages ; and it is quite evidence enough that the matter, 

 no less than the manner of the lectures of Dr. Young, 

 were more fitted for Cambridge than for the Eoyal 

 Institution. 



Dr. Paris thus contrasts Davy's manner with that of 

 Young : 



To judge fairly of the influence of a popular style we 

 should acquaint ourselves with the effects of an opposite 

 method, and, if an appeal be made to experience, I may very 

 safely abide the issue. Dr. Young, whose profound 

 knowledge of the subjects he taught no one will venture 

 to question, lectured in the same theatre, and to an audience,, 

 similarly constituted to that which was attracted by Davy , 

 but he found the number of his attendants diminish daily , 

 and for no other reason than that he adopted too severe am.! 

 didactic a style.
