The following papers have been circulated to some extent in 

 the form of slips reprinted from the reports made by the 

 Secretary of the Society in the " Boston Transcript." As here 

 presented, the papers are printed in full, aiid the discussions, 

 where it appeared necessary, have been carefully revised by 

 the speakers. 



The Committee on Lectures and Publication take this oppor- 

 tunity to repeat what they have before stated, that the Society 

 is not to be held responsible for the certainty of the statements, 

 the correctness of the opinions, or the accuracy of the nomen- 

 clature, in the papers and discussions now or heretofore pub- 

 lished, all of which must rest on the credit or judgment of the 

 respective writers or speakers, the Society undertaking only to 

 present these papers and discussions, or the substance of them, 

 correctly.
