Captain Hutton exhibited slides of Galway serpentine con- 
taining Eozdon. He stated that in the winter of 1862-63 Sir W. 
Logan sent specimens of serpentine from the upper portion of the 
lower Lamentian formation, and ‘which he supposed to be of organic 
origin, to Dr. Dawson, of Montreal, for microscopic examination. 
Dr. Dawson at once pronounced them to be portions of a huge 
Foraminifer, which he named Hozdon Canadense, and which, he said, 
probably formed reefs in those seas equal in size to the coral 
reefs of the present day. These statements have been confirmed, 
in every respect, by Dr. Carpenter, who adds that he believes 
that a more thorough examination of some of the Silurian fossils 
(such as Stromatophora), hitherto marked amongst corals and 
sponges, will prove that they are really, like Eozoon and Recepta- 
culites, gigantic Foraminifera. Captain Hutton’s attention was 
drawn to the subject by a letter in the ‘ Geological Magazine’ for 
the present month, from W. A. Sanford, F.G.S., of Wellington, 
Somerset, in which he says that he had sent slides of Irish green 
marble from the Binabola Mountains, Connemara, to the editor, 
which slides he thought contained Eozoon, and Professor Rupert 
Jones confirmed the supposition. Captain Hutton therefore ob- 
tained some specimens ct the serpentine from Dr. A. Carte, pre- 
pared them, and found them to contain markings in all respects 
similar to those figured in vol. xxi, part 1, of the ‘ Quarterly 
Journal of the Geological Society,’ and which he therefore pre- 
sumed were Eozdon. Captain Hutton also exhibited a diagram, 
drawn to scale, of the maximum thicknesses of the various sediment- 
ary rocks, as at present known, from which it appeared that the 
horizon of the “ Lingula-flags ”’ occupied a position just half way 
between the horizon of Eozéon and the most recent formations, 
from which he inferred that the interval of time between the 
Eozéon and the Lingula-flags was, at least, equal to that between 
the latter and the present day.

Tuts Society held its annual meeting in the Grammar School, 
on Tuesday, the 10th January, at 7.30 p.m. The Society has been 
in existence for little more than a year, and already numbers up- 
wards of seventy members. Nine meetings had been held during 
the previous year, at each of which very useful papers were read, 
some being of great excellence and involving a great amount of 
research. At the meeting above referred to the following gentle- 
men were elected office-bearers for the ensuing year: 
President. . . . Dr. Oartnvre, Aberdeen University. 
Gee ee csidonts { Professor Nicon, Aberdeen University. 
: Mr. H. A. Suiru, 3, King Street. 
Secretary. . . . Rev. A. Beverty, Grammar School. 
Treasurer . . . Mr. Geo. Warxer, 77, Union Street.
