As bearing on tlie discussion in these pages already referred to, the 
following extract from a letter from Mr. Macvicar to the writer may 
be of interest, as embodying what Mr. Waddell regretted the absence 
of— naniel)', the opinion of an extra-IIibernian botanist : — " I sympathise 
with the view which considers it inadvisable to continue the Irish numbers 
in succession to Shetland This matter must be left to Irish 
naturalists to settle in the manner they think best. In my opinion, 
English naturalists must adopt the numbers which are generally agreed 
upon as satisfactory by those in Ireland, when giving the British Isles 
as one botanical or zoological region."

It would be impossible within the compass of a short review to do 
justice to the valuable memoir which has lately been issued with the 
drift map of the environs of Cork. 
The map itself, which shows evidence of most extensive and painstaking 
work, should be of the highest utility to all interested in the surface 
formation of the land around the City and Harbour of Cork. 
The scale is one inch to the mile, and the size 18 inches by 12. The 
ground covered includes portions of four sheets of the regular one- 
inch Ordnance Map, the town of Passage marking approximately the 
middle point of the area. 
A section is shown through the central portion of the district, cutting 
the transverse ridges at right angles, and consequently running nearly 
north and south. 
The Memoir occupies 126 pages, and is divided into three sections. 
The first or " General Description " deals with the wider and deeper 
geology of the area, incliiding the form of the ground and descriptions of 
the main formations, viz., the Old Red Sandstone, the Carboniferous 
rocks, and the Post-Tertiary or superficial deposits (49 pp). 
The writers adhere to the original theory of Jukes with regard to the 
peculiarities in the direction of the rivers of the district, and reject, for 
reasons which they give, the later suggestions of Prof. K. Hull and Mr. 
J. Porter, B.B. 
The following passage from the chapter on the Carboniferous Rocks 
may be of melancholy interest to those who still dream of coal mines in 
South Cork :— " In the original survey two or three small tracts
