of the fine collections made by Mr, Sears at the Poabody 

 Academy of Science. 



Monday, April 11, 1892.— Dv. Philip C. Knapp of Bos- 

 ton, lectured on "Hypnotism." The speaker after stating 

 that hypnotism was by no means a new discovery, pro- 

 ceeded to give some historical account of it from the time 

 it was first heard of in the sixteenth century down to the 

 present time. He then gave a detailed statement of what

 under its influence might be led to do improper acts, sign 

 papers, impart information, or commit crimes. 



Monday, April 25, 1892.— Ron. Alden P. White read 

 in the lecture course, in a most interesting manner, selec- 

 tions from the poet Tennyson, which best illustrated the 

 story of "The Passing of King Arthur" as told in the old 

 legends of the Round Table. A short informal talk on 

 the subject preceded the reading. 



Monday, May 2, 1892.— Ezra D. Hines , Esq., of Dan- 

 vers lectured, his subject being "A Day at Lexington." In 

 a most entertaining manner, he gave a full account of a 

 visit of the Danvers Historical Society to Lexington in
