tee be appointed." Dr. Embleton tlien delivered a most lucid and 

 illustrative discourse, " On the Circulation of the Blood," minutely 

 detailing the functions of the various organs concerned in this 

 wonderful operation, and illustrating his remarks by a series of 

 excellent diagrams, and by a large number of beautiful micros- 

 copical preparations of blood gobules, lung tissue, and capillary 

 vessels of the various classes of animals. A vote of thanks, on 

 the motion of Mr. Fenwick, was accorded to Dr. Embleton by 

 acclamation.

 our " Transactions," were also read : —

The Second Evening Meeting was held on Friday, December 

 10th, and was attended by thirty members and friends. After 

 partaking of an excellent tea, four new members were elected, 

 and a paper by Mr. Albany Hancock, " On certain Vermiform 

 Fossils from the Mountain Limestone Deposits of Northum- 

 berland and Durham," was read. Mr. Hancock, in a remarkably 

 clear and lucid manner, showed their analogy with the runs or 

 burrows of some small Crustaceans, now common on our coasts, 

 specimens of which he exhibited. A fine series of Fossil tracks 

 were also displayed, as well as a number of specimens of the 

 Fossil Crustaceans, or Trilobites, to which Mr. Hancock attri- 

 butes these curious tracks. The paper was remarkable for the 

 admirable logical sequence of the arguments advanced, and the 

 clearness of the reasoning ; and it will form an important contri- 

 bution to our " Transactions." 



The thanks of the meeting were voted to the author by accla- 

 mation, after which the following papers were read: — 



1. "Notes on Northumberland Plants." By Mr. Daniel 

 Oliver, jun., F.L.S.
