 and Dr. Clanny ; and if the object of the Committee was to re- 

 ward priority and ingenuity, why did they pass over the latter-of 

 these gentlemen, who actually did produce a lamp that might have

LECTURES. 



Mr. Bakewell will commence his Series of Lessons on Geo 

 logv at the Argyle Rooms early in March, to be elucidated by a 

 magnificent suite of Rock Specimens recently collected by him- 

 self, and by a great variety of new and original drawings, sections, 

 and models. 



Mr. Bakewell is also preparing for publication A Treatise on 

 Practical Geologv, with Plates : to which will be added, A Series 

 of Questions addressed to British Geologists on certain undeter- 

 mined Parts of English Geology, &c, 



Mr. Dovvling's Lectures on Natural Philosophy, Astronomy^ 

 and Chemistry, begin after the Christmas Recess, on the 3d of 

 February. The Lectures on Philosophy are illustrated by a com- 

 plete set of apparatus ; those on Astronomy, by machinery, trans- 

 parencies, transit instruments, and several very powerful tele- 

 scopes ; and the Lectures on Chemistry are rendered peculiarly 

 interesting by numerous beautiful and useful experiments. These 

 Lectures are regularly delivered at the Lecture Room and Ob- 

 servatory, Mansion-House, Higligate ; and Mr. Dowling spares 

 no pains to render them as effective as possible, bv familiarly ex- 

 plaining the difficulties that occur, and by blending the utile cum 

 dulci .
