In addition to these lectures, there were readings from English and 

 American authors by Mr and Miss Dietz, and a Pianoforte Recital by 

 Herr Pauer, both of which were attended by large audiences. 



Following the example of previous Sessions, and with a view of 

 making the studies of the Society somewhat more systematic, the Com- 

 mittee arranged with Professor M'Kendrick to deliver a series of four 

 lectures. 



The subject selected by the Professor for these lectures was, as 

 already stated, "Nerves and Nerve Centres," and their success was such 

 as to confirm the Committee in the belief that a short series of lectures 

 should, if possible, be given each year on one subject. 



The Watt Anniversary Lecture was delivered by Professor Balfour 

 Stewart, of Owen's College, Manchester. 



The Society desires to record its high appreciation of the kindness 

 of Lord Gifford in again favouring it with a lecture, and in coming from 

 Edinburgh, at great personal inconvenience, to open the nineteenth 

 Session with a very eloquent and instructive lecture on " Transcenden- 

 talism." The warmest thanks of the Society are due to Dr Macmillan 

 who, on very short notice, undertook to deliver his lecture on " The 

 Roman Forum." When the programme of the second half of the past 

 Session appeared, the Members of the Society would doubtless notice 

 with gratification that the venerable and respected pastor of the West 

 Parish Church would again, and for the third time, lecture to the Society. 

 Unfortunately, the health of Dr M'Culloch was such as to preclude him 

 from delivering the lecture in person, but the Committee are happy to 

 know that the results of the studies of some of the maturer years of the 

 Reverend Doctor were listened to with much pleasure and profit, 

 interpreted as they so ably were by the President. The Society is 

 also much indebted to Graham Brymner, Esq., for the very interesting 

 and instructive lecture with which he brought the Session to a close. 

 The Committee regret that the state of the funds will not permit of any 

 grant being made this year for the purchase of scientific books of reference.
