[A collection of the so-called " Kelpies' Feet," from the micaceous flajcstoncs of 
North Britain, from the Museiun of Practical Geology and the Society's Museum, 
were exhibited at this Meeting.] 
January 19, 1859. — The following communications were read : — 
1. "On the Gold-field of Ballaarat, Victoria." By II. Resales, Esq. Commu- 
nicated by W. W. Smyth, Esq., Sec. G. S. 
Mr. Rosales described the position of the quartz-lodes (the matrix of the gold) 
in the schists of the hill-ranges, from whence originate the numerous auriferous 
gullies, forming eventually several channels (charriages), and the different courses 
of the old gold-bearing streams, which gradually passing to lower levels, reach the 
great areas of basalt, under wliich they continue their hidden course. To illus- 
trate these points, the author prepared and sent a MS. map of the district from 
beyond Buninyong to Creswick, on which the granite, basalt, schists, and quartz 
loaes were shown, as well as the gold-channels, gullies, nuis, leads, &c., connected 
with which 9(j named spots or diggings were carefully indicated. 
2. " Description of a New Species of Cq)halaspis (C. Astcrolepis) from the Old 
Red Sandstone of the neighbourhood of Ludlow." By John Harley, Esq., Sub- 
dean, &c., King-'s College. Conununicated by Prof. Huxley, F.G.S. 
This new form of Uephalaspis (from Hupton Gate) is at least twice the size of 
C. Lyellii, and is further characterized by the position, obliciuity, and magnitude 
of the orbits. The space between the orbits is proportionally small, and the occi- 
pital crest very short. The outer enamel-layer is ornamented with tubercles, 
wliich, tliough somewhat variable, bear so close a resemblance to those covering 
the bony i)lates of Asterolepis, as to have suggested the sjiecific name. The inner 
layer of the bony plate presents lacuna; and canaliculi resembling tho.se of human 
bone ; and many of them, in the specimen described, are naturally injected with a 
transparent blood-red material, so lUstinctly and delicately, that in their minutest 
details the structure of canals not more than jouo uth of an inch in diameter is 
beautifully revealed. 
Mr. Harley also described a more perfect specimen of Cephalaspis Salweyi than 
the one on which Sir P. Egerton not long since determined the species. It was 
found by Mr. Salwey at Hinstone near Bromyard. Associated with the C. Sal- 
weyi, the author found a specimen of either a dermal plate or a tooth of a placoid 
fish, resembling some Siluiian fossils called Ccelolepidce by Pander. 
Geologists' Association. — On Tuesday, the 11th Jan. instant, the First Ordi- 
nary Meeting of this Association was held in the Library of St. Martin's HaU. 
There were nearly 200 persons present. 
The proceedings commenced by the election of several new members, after which 
the President, Mr. Toulmin Smith, proceeded to deliver an inaugural address. 
In opening the subject, the President directed special attention to the importance 
of finding true facts ; he stated that it had been well observed that there are even 
more false facts than there are false theories in the world. 
He remarked that Geology is a science which rests exclusively on a knowledge 
of the outer world, and can only exist as a science in the true interpretation of the 
facts which that world shows to us ; that there is no science which has been, and is, 
liable to be more hindered hy false facts. There is none, therefore, in which the gather- 
ing up of trae facts, and the bringing them together as a common stock for tlie use 
of science, can be more needed. This being so, there appear to be good reasons 
for the work set to itself by the " Geologists' Association." Beyond the mere 
advancement of the common stock of knowledge by means of association, it was to 
be hoped that the enterprise of this country might be materially helped by its 
labours, and that it, in return, would receive its reward in being made the deposi- 
tory of many facts and obseiwations, wliich, but for its existence, would remain
