 autumn holiday. The only serious contretemps that occurred was 

 that one of the days devoted to excursions proved wet and stormy 

 But supplies for the mind, no less than for the body, were pro- 

 vided ; and the general interest of the papers and their numbers 

 did not in any degree fall short of former years. As was to be 

 anticipated, Scotchmen took a prominent part in the reading of 

 papers. Of course, a large proportion of the papers bore upon 

 subjects not peculiarly Scotch ; but, as will be seen from the list 

 of headings below, a considerable number of papers of really local 

 interest were read, especially in the Geological section. 



Of Scientific Exhibitions there were several. Besides the 

 Museums in the University buildings, a loan exhibition was 

 shown, restricted to specimens from Scotland north of the Tay. 

 There were many interesting and valuable objects included in it, 

 thanks to the kindness of the directors of the Museums of Forres, 

 Elgin, Banff, and Montrose, the Dundee Naturalists' Society, and 

 many private individuals, through whose generous assistance some 

 idea of the fauna, flora, and geology of the north of Scotland 

 could be gained by the strangers during even the few days spent 

 in Aberdeen. 



The presidential addresses dealt largely with the educational 

 bearings of scientific studies. Professor MTntosh, of St. Andrews 

 "University, however, took as the subject of his interesting address, 

 the phosphorescence of marine animals ; and Professor Judd, in 

 the Geological section, spoke " On some Great Problems in High- 

 land Geology," summing up the conclusion generally admitted by 

 Geologists within the past year or two, and adverted to in previous 

 numbers of this Journal. In his address he bestowed on the late 

 Professor Nicol the tribute due to him for the accuracy of the 

 conclusions to which he had come in regard to this most difficult 

 problem, and which were for many years not allowed a hearing 

 because of the influence of Murchison in opposition to them. 



Space will not permit the insertion of more than the headings 

 of the local Scotch papers read before the meeting.
