282 Reports and Proceedings— 
plete list of the various works, articles and notes published by Heer, 
arranged according to their dates of publication, which extend from 
1832 to 1884. This list comprises from 270 to 280 titles, and it is 
followed by lists of the fossil animals (except the insects) in “ Die 
Urwelt der Schweiz” ; of the insects figured in Heer’s various works, 
and of all the fossil plants described and figured by Heer. As the 
references include the page, plate, and number of figure for each 
species, it is evident that the work will prove of immense service to 
paleobotanists and others desirous of consulting Heer’s works. I 
can state from my own experience that it has already been of much 
service to me, and a great saving of time and trouble, and M. 
Malloizel deserves the thanks of all paleobotanists for undertaking 
the tedious task of preparing this compilation.

I.—April 25, 1888.—W. T. Blanford, LL.D., F.R.S., President, 
in the Chair.—The following communications were read :— 
1. “Report on the Recent Work of the Geological Survey in the 
North-west Highlands of Scotland, based on the field-notes and maps 
of Messrs. Peach, Horne, Gunn, Clough, Hinxman, and Cadell.” 
Communicated by A. Geikie, LL.D., F.R.S., F.G.S., Director-General. 
At the outset a review was given of the researches of other 
observers, in so far as they forestalled the conclusions to which the 
Geological Survey had been led. Reference was made to the obser- 
vations of Macculloch, Hay Cunningham, C. W. Peach, and Salter ; 
to the prolonged controversy between Sir Roderick Murchison and 
Professor Nicol ; to the contributions of Hicks, Bonney, Hudleston, 
Callaway, Lapworth, Teall, and others. It was shown that Nicol 
was undoubtedly right in maintaining that there was no conformable 
sequence from the fossiliferous quartzites and limestones into the 
eastern schists. It was also pointed out that the conclusions of 
Professor Lapworth regarding the nature and origin of the eastern 
schists involve an important departure from Nicol’s position, and 
are practically identical with those obtained independently by the 
Geological Survey. 
The results of the recent survey work among the Archean rocks 
may be thus summarized :—(1) the eruption of a series of igneous 
rocks of a basic type in which pegmatites were formed; (2) the 
development of rude foliation in these masses, probably by mechanical 
movement, and their arrangement in gentle anticlines and synclines, 
the axes of which generally run N.H. and 8.W.; (8) the injection 
of igneous materials, mainly in the form of dykes, into the original 
gneisses, composed of (a) basalt rocks, (b) peridotites and paleo- 
picrites, (¢) microcline-mica rocks, (d) granites; (4) the occurrence 
of mechanical movements giving rise to disruption-lines trending 
N.W. and S.E., E. and W., N.E. and S.W.; (5) the effects of these 
movements on the dykes were to change the basalt-rocks into diorites
