The Committee had directed 200 copies of this Part to be printed. 

 They had also found it necessary to print 200 copies of Judge Davis's 

 Eulogy upon Washington, belonging to the second part of the same 

 volume. This republication will enable the Academy at once to real- 

 ize 92 complete sets of the First Series of Memoirs ; and the reprint 

 hereafter, when the necessity arises, of another small portion, will 

 make complete 100 more sets. For there are in the possession of the 

 Academy 237 copies of Volume I. There are only 3 copies of Vol- 

 ume II. There are 18 additional copies of Part II. of that volume. 

 There are also 100 additional copies of Part II., with the exception 

 of Judge Davis's Eulogy on Washington. There are besides 68 

 extra copies of Plate I., 27 extra copies of Plate II. ; and the stone 

 on which the illustration of Dighton Rock is drawn is also in posses- 

 sion of the Academy. Of Volume III. there are 57 complete copies. 

 Then there are 64 separate copies of Part I. and 35 of Part II. Of 

 Volume IV. there are 245 complete copies ; and, in addition, 3 of 

 Part I. and 78 of Part II. 



As the 24 additional pages to be printed, and the supply of three 

 woodcuts and a lithographed plate, have made the cost of republication 

 exceed by $50 the appropriation for this special purpose ($200), the 

 committee recommend that a subscription paper be opened to members 

 of the Academy for complete sets of the Old Series of Memoirs, at 

 $3 a volume, or S 12 the set. If 20 sets were purchased, the cost of 

 republication would be repaid to the Academy, and 72 complete sets 

 would remain immediately available. 



Dr. Jenks gave an account of the organization of a literary 

 and scientific society at Shanghae. 



Dr. J. B. S. Jackson exhibited a portion of a glass tube 

 which was accidentally broken while drawing a sponge through 

 to clean it ; one piece of which exhibited a very regular spiral 

 crack running from end to end. 



Professor W. B. Rogers said he thought the direction of 

 the crack might result from an equality between the cohesive 

 attraction of the particles in a transverse and longitudinal 

 direction, causing the line of fracture to follow the diagonal 

 of these forces.
