Images of the map (LDGSL/246), showing the split down the middle and the dirty and damaged edges. The paper is thin but good quality.

This large map, by Loring Woart Bailey (1839 -1925) and George Frederic Matthew (1837-1923), would have been displayed in the Society’s Meeting Room whilst the paper by the latter “On the Azoic and Palaeozoic Rocks of Southern New Brunswick” was being read on 10 May 1865. 
 
Although the Geological Survey of Canada was founded in 1842 the areas available for it to survey were limited as the country was still split into regions which were controlled by different countries or private companies. The result was a rather piecemeal approach to mapping, usually confined to specific areas.
 
Matthew claimed that his paper and accompanying map were a revision of previous surveys of New Brunswick which had recognised the local rock series but had failed to identify their respective ages. The map focuses on the Palaeozoic formations found in New Brunswick, correlating them with the British stratigraphical system.
