shells; and, with these, I include two or three rounded lumps of what 
appears to be an impure graphite. 
There is no Upper Boulder-clay in the Cemetery-ground ; but 
small and shallow breadths of it appear at intervals along a course 
of two or three miles to the west; and, at this point, the Drift- 
deposits reach their maximum thickness, about 300 feet; and this is 
at an elevation of about 600 feet above the level of the sea. 
T also exhibit a cast of a Net-sinker. The original, which I have 
presented to the British Museum, is made of burnt clay, and is 
probably of very early English date. It was discovered a few feet 
below the surface, in the lower part of the valley. 
The Fulgurite which I have brought for your inspection was got 
out of a bed of fine dry sand on the south side of Macclesfield, about 
three years ago ; it was traced in a straight direction to a depth of 
22 feet. This was a work of some difficulty, owing to its brittle- 
ness, and only short lengths of it were at intervals secured. Towards 
the surface its diameter had been about three-quarters of an inch, 
and it tapered gradually throughout its course to about 3 or 4 
feet from its termination, when it took a slanting direction, and then 
assumed the form of several filaments, which eventually became 
dispersed and obliterated in a soft spongy clay.— Macclesfield Courter

GroLocicaL Soctety oF GLAscow.—On Saturday, May 1sth, 
the Society had their first Excursion of the summer session to the 
Rye Water and surrounding district, undee the guidance of Mr. 
James ‘Thomson. 
The Rye Water, to which Mr. Thomson first led the party, 
is a small stream—a short distance from the town of Dalry 
—which receives the drainage of the range of hills forming the 
northern boundary of the Ayrshire Coal-field. Its banks exhibit 
many interesting and instructive sections of Carboniferous strata ; 
in some parts they have been cut to a considerable depth by the 
stream, exposing the strata from the lower nodular Ironstone of the 
Ayrshire basin, down to the base of the Mountain-limestone,—all 
of which beds have been much disrupted by numerous dykes of 
greenstone and coarse gritty tufa. : 
On the way, a visit was made to some ironstone pits, where the 
lowest black-band is found, 2 feet in thickness ; and after a walk of 
a mile over gently rising ground, the party struck the Rye Water 
at a section where the lower nodular ironstone is exposed, and a 
bold escarpment of rocks is seen, tilted up by a trap-dyke, which 
dips to the south with a strike EK. to W. After an examination of 
this section, the stream was ascended for a short distance to a section 
on the east bank, where the lowest black-band ironstone is exposed, 
and had led to the search for an extensive working of this seam in 
the surrounding district. 
A little farther up the stream, the party reached the high cliff at 
Cuningham Badlane, on the west bank, exhibiting one of the finest 
sections in the West of Scotland. This section is composed of Car-
