Contributions towards a Cybele Hibernica, being Outlines of the Geogra- 
phical Distribution of Plants in Ireland. By D. Moore, Ph.D., and 
A. G. Mors, F.L.S. Dublin: Hodges, Smith, and Co. London: 
Van Voorst. 8vo. Pp. 399. 
This is a work the appearance of which will be welcomed by all 
who are interested in geographical botany. The distribution of spe- 
cies through Britain proper being ascertained and registered with 
greater detail and precision than has been anywhere else attained, it 
became a point of much interest to know clearly which of them 
reached Ireland, and how these were dispersed abroad over its surface. 
The published material for information was scattered and scanty. It 
is now thirty years since the issue of Mackay’s ‘ Flora Hibernica, and 
the work did not profess to do more for Ireland than the * British 
Flora’ did for Britain. There are in the whole island but two good 
and full local Floras, Dr. Power's * Botanist's Guide for the County of 
Cork, and Professor Dickie's * Flora of Ulster, and Botanist's Guide 
through the North of Ireland,’ and a few lists and records of excur- 
sions scattered amongst the periodicals and transactions of the Dublin 
Society and Botanical Society of Edinburgh. Dr. Moore and Mr. More 
have adopted the twelve provinces sketched out several years ago by 
Professor Babington, and have traced out the distribution of each 
species through these as well as they could by means of the published 
records, their own field observations, and the help of the few resident 
collectors scattered through the country, carefully sifting the list, re- 
jecting many species and stations which rest upon doubtful or uncon- 
firmed authority, and furnishing a classified list of special stations for 
all but the commonest plants. The work is in a conveniently portable 
form, and is illustrated by a coloured map of the twelve botanical pro- 
vinces; and it is probable that we get a better book from both of them 
working in combination than either could have produced separately, 
or than could have been furnished by any one else. : 
The range of average temperature in Ireland does not differ mate- 
rially from that of England. The isotherm of the Cork and Kerry 
coast is about the same as that of Helston and Ventnor, 52 degrees, 
and that of the north-east is from 47 to 48 degrees, the same as
