ACADEMY OF NATURAL SCIENCES. 69 



A second series of the Journal of the Academy was commenced 

 in December, 1847. It is in quarto form, and is furnished to sub- 

 scribers at one dollar and a half the number. Six numbers have 

 been published; four of which constitute a volume. This new 

 series embraces at this time forty-five articles by twenty authors, 

 with fifty-nine handsome plates or illustrations; the aggregate 

 consists of five hundred and forty quarto pages :

The authors of contributions receive no remuneration for their 

 labors. These periodicals are sustained by subscription, assisted 

 by a legacy from the late Mrs. Elizabeth Stott. She bequeathed 

 two thousand dollars, to be securely invested, and the interest to 

 be expended in " printing and publishing such papers communi- 

 cated to the Academy, as it may direct," to be published. It is 

 expended exclusively on the Journal. 



As already stated, the founders of the Institution were seven 

 in number. Since the 16th of April, 1812, when the first election 

 took place, up to the 31st of December, 1851, 420 gentlemen and 

 1 lady have been elected members, making an aggregate of 428. 

 Of this number 112 became "life members," 38 of whom are 

 known to be deceased ; so that there are 74 members at this time 

 exempt from the payment of annual contributions. Of the 317 

 ordinary members, 46 are known to have deceased ; many have 

 removed from the city, some have resigned, and a few have been 

 erased from the list of members. The books of the treasurer 

 show that, in the year 1861, there were only 69 annual sub- 

 scribers ; so that at this time, the number of members does not 

 probably exceed 200.
