With the exception of two, the lectures announced on the cards 
were delivered. Mr. W. Harvey, who should have lectured on 
December 19th, being prevented from doing so by severe illness, 
his place was supplied by Mr. W. Square, who read a paper on 
"Digestion;" and Eev. Professor Anthony being unable to read 
his paper on " Cicero's Letters," as announced, Mr. C. Spence 
Bate read a paper on the "Evidences of the Scandinavian on 
Dartmoor," and thus papers were read and discussed upon every 
Lecture evening of the Session. 
The average attendance at the Lectures has been sixty-three, 
which is about the same as during former Sessions ; doubtless it 
would have been larger had it not been for the severe and incle- 
ment weather during the winter, and the feeling on the part of 
many of the Members and Associates that the hour of meeting is 
too early. 
The Society is much indebted to the Eev. Professor Beal, an 
Honorary Member of the Institution, who, at much personal in- 
convenience, and during most inclement weather, travelled from 
Ealstone, Northumberland, on the 6th March, in order to fulfil 
his engagement, and read his paper on "Mithras." 
One lecturing member, fourteen associates, and one lady associate 
have joined the Society during the year, the numbers on the books 
now being seventy-one members, one hundred associates, eight lady 
associates, and two junior associates. 
The Society has lost by death three of its Members ; viz., Mr. 
Edward Spender, whose sad fate on the coast of Cornwall, in June, 
1878, was deplored by all who knew him; the Kev. Dr. Holmes, 
formerly President of the Institution, who read many valuable 
papers within its hall, died in October, 1878, and was followed 
to the grave by a large number of the Members and Associates ; 
also a promising young Member, Mr. S. N. Serpell.
