A New Map. 
Much has been done by the Geological Survey and others in 
exact surveying and mapping in Nova Scotia and Cape Breton 
since 1868. The publication of a progress map on a larger scale 
than the maps of Acadian Geology, indicating the work thus ac- 
complished, is certainly a great desideratum.

The Author’s Maps in the Museum portfolio, constructed to 
illustrate papers on Nova Scotian Geology read before the Insti- 
tute, which were exhibited at the American Centennial Exhi- 
bition. 
To these have been added a Map of a part of Annapolis 
County and a Map of a part of King’s County, which were also 
made to illustrate papers read. 
GEOLOGICAL SOCIETY. 
I have referred to the abstract of my paper “on the Lauren- 
tian Rocks of Arisaig,” which appeared in the Journal of the 
Geological Society. This, like many abstracts of papers not 
made by the authors, seemed to me not to do justice to my 
paper ; still, I regard the abstract as valuable, as it is the first 
description of this interesting series of rocks in a scientitic 
journal. I regard the nature of the discussion as also interesting 
and useful. 
I would observe that the publication is also to be valued, as it 
led to the production of a very valuable note by Prof. T. Rupert 
Jones, on Hntomostraca from Arisaig, “D, Upper series,” which 
J had given to him in 1862.
