gneissose rocks and conglomerates, especially on the bare glaciated 
surfaces, and suggests that many of the smaller and shallower 
lakelets may have originated by this process. 
The conglomerates are described as gneisses and mica-schists, with 
subordinate pebble-beds. 
The occurrence of gold in quartz-veins near Flinders, and at 
Madog, is noted; and amongst other economic products are the micas 
of the granites, asbestiform actinolite, and marble. The author dis- 
cusses the mode of origin of the granite, marble, and actinolite-rock.

SELENOLOGY. 
Srr,—Pressure of other work has caused me to overlook until 
now Mr. Peal’s short but suggestive article in the last number of the 
GeoLtocicAL Magazine (Nov. 1892, pp. 500-502). Perhaps it may 
not be now too late to call Mr. Peal’s attention to certain queries 
and suggestions published by myself in 1889 (App. ii. Note O, to 
my little work on “ Metamorphism of Rocks”). I venture to think 
that some of these, suggested by an attempt to look at the matter 
from the chemico-geological standpoint, have hardly occurred to 
Mr. Peal. I will only note now two points: (1) that other tides 
than oceanic aqueous tides have to be allowed for; (2) that volcanic 
action is not under all circumstances dependent on water as an agent.

Sir,—The last paragraph of Mr. A. R. Hunt’s letter (p. 573) is 
the most ingenious instance of misrepresentation by selective quota- 
tion that I have seen for a long time. Against such an antagonist 
I cannot contend. So I leave him to enjoy the illusion that particular 
difficulties are best solved by general ignorance (see paragraph three 
of his letter), and to metamorphose not only the rocks of Devon, 
but also my papers to his heart’s content.
