478 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [Apr. 27, 
Mines in his Report for last year* :— The most noticeable feature 
in this district is the tracing of the southern outcrop of the cele- 
brated Tudor Lode, by a series of openings connecting two points 
1100 feet distant, and thus proving the correctness of the views 
entertained by Professor Hind of the geological structure of this 
district, as described in his report and fully exemplified in the map 
accompanying that Report.” 
They are also noticed by the Inspector of Mines, who states :— 
“'The trending of the strike of this lode towards the north and east 
has been followed from the shafts to within a few feet of the old 
workings on the Tudor Lode; and its identification with that lode 
has been established, and the construction assigned by Professor Hind 
to this part of Waverley district confirmed” 7.

Principal Dawson spoke in confirmation of the fact that the 
Paleeozoic rocks are underlain by Laurentian gneiss &c. quite to 
the eastern coast of British North America, and stated that the 
same relation occurred in Newfoundland, and had been traced south- 
wards into Massachusetts. He confirmed Mr. Hind’s views gene- 
rally, and stated that the Lower Silurian of Nova Scotia includes no 
great fossiliferous limestone lke that of the interior of North 
America. The supposed Hozoon discoverea by Dr. Honeyman was 
probably distinct from H. canadense, but was certainly a Foramini- 
feral organism allied to Hozoon ; but as Hozoon bohemicum is of 
later date than LH. canadense, the presence of Hozoon did not neces- 
sarily indicate Laurentian age. 
Prof. Ramsay suggested that other organisms besides Hozoon aided 
in building up these great calcareous masses. He inquired as to 
the mode of occurrence of gold, and suggested that the gold is ob- 
tained at the anticlinals merely because the exposure is better, and 
that it will be found to pervade the synclinals also.
