MINERALOGY. 



The study of this useful science has been much retarded by the difficulty of 

 obtaining a Collection, and the high prices generally asked for peculiar Specimens. 

 "With a view to obviate this, Mr. Ma we has been induced to form Portable Col- 

 lections, classed and arranged, with a Catalogue, at Twelve Guineas ; larger 

 Cabinets, containing two hundred and fifty Specimens, at Fifteen Guineas ; others, 

 containing upwards of three hundred Varieties, Twenty Guineas. Collections, 

 consisting of five hundred larger and fine Specimens (without Cabinet) Fifty 

 Guineas. 



Any Specimens may be exchanged, if required ; and the Collection may be 

 formed peculiarly rich in any given Class. 



Large, elegant and rare Minerals at reduced prices. Precious Stones, Minerals 

 and Shells, purchased. 



A great Variety of elegant Vases formed and enriched after the Antique. 

 At No. 149, Si rand. Three Doors West from Somerset-house.
