Griffin's Cheap Chemical Apparatus. 



The subscribers have on sale every kind of French, German, and 

 English Chemical Apparatus, employed by Analytical Chemists, 

 Lecturers, Students, and Chemical Manufacturers. The instruments 

 are of the newest and most useful kinds, such as are employed by 

 Berzelius, Liebig, Rose, Mitscherlich, Dumas, Gay Lussac, Fara- 

 day, Graham, and other eminent chemists. The establishment is 

 under the superintendence of John Joseph Griffin, author of 

 "Chemical Recreations," and translator of " Rose's Manual of An- 

 alytical Chemistry," who has recently visited the principal chemical 

 laboratories and instrument-makers in France, Germany, and Eng- 

 land, for the purpose of collecting the best patterns of the apparatus 

 at present employed both in Organic and Inorganic Chemistry. 



The central position of Glasgow has recommended it as a suitable 

 place for a Depot of Philosophical Apparatus. Being only one day's 

 sail from Liverpool, it is at all times easy to send goods from it to 

 New York or Boston. - - •••• M
