14. MINERALOGY. 



The collection of minerals is arranged in the east basement- 

 room. 



As early as March, 1812, Mr. John Speakman, in anticipation 

 of the wants of the Institution, purchased from Dr. Seybert, for 

 the sum of $750, a collection of European minerals ; but this 

 acquisition bears a later date on the records of the Institution. 

 In July, of the same year, $370 were subscribed by members to 

 purchase Mr. Godon's cabinet ; but at the auction, Prof. B. S. 

 Barton bid a larger sum and obtained it. The late Mr. Joseph 

 Watson (of the firm of Watson and Bell) purchased the same 

 collection at Dr. Barton's sale and presented it to the Academy.
