172 Proceedings of the Royal Society of Edinburgh. [Sess. 
stated, is an atlas of Meteorology. The fourth was to be devoted to 
Botany, the fifth to Zoology, the sixth to Ethnography and Demography, 
and the seventh to General Cosmography and Terrestrial Magnetism. It 
was to include in all 212 plates, the titles of which are given in the 
prospectus. The prospectus states that the other sections will follow that 
on Meteorology in rapid succession, and, if the fact that this anticipation 
proved too sanguine will surprise no one who has had anything to do with 
the preparation of comprehensive works even on a much smaller scale 
than this, it may be taken as a typical illustration of the patient tenacity 
that characterised Dr Bartholomew in all his work that a second volume of 
the series, the Atlas of Zoogeography, was at last published in 1911, as well 
as that many other plates belonging to other sections not yet published 
were prepared under Dr Bartholomew’s direction. 
It will serve to give some idea of the magnitude of the whole under- 
taking to compare the two sections of the atlas which have been published 
with the corresponding sections of the atlas of Physical Geography that 
had the first place at the time when that of the Edinburgh Geographical 
Institute began to be published, Berghaus Physikalischer Atlas. To begin 
with, the size of the plates in the Edinburgh atlas is considerably larger 
than those of Berghaus — measured from the outer limit of the border 
(exclusive of margin) 19J"xl5f", as against 16"xl3". The section on 
Meteorology in the Edinburgh atlas has 34 plates (35, including the 
frontispiece plate showing the distribution of meteorological stations in the 
world at the time of publication) as against 12 in Berghaus, and an intro- 
ductory text of 40 pages, besides an appendix of 12 pages (4 giving a list 
of meteorological stations, 4 a bibliography, 2 a glossary, and 2 tables), as 
against 10 in Berghaus; that on Zoogeography has 36 plates as against 9 
in Berghaus, together with an introductory text of 56 pages, exclusive of 
a bibliography of 11 pages, as against a text of 8 pages in Berghaus. 
All those primarily responsible for the Atlas of Meteorology are now 
dead. It was prepared by Dr Bartholomew himself in association with 
the late Professor Herbertson, under the editorship of the late Alexander 
Buchan, LL.D., F.RS. Among its new features may be mentioned several 
maps illustrating isanomalies of temperature, maps showing isonephs, or 
lines marking the limits of equal degrees of cloudiness, and isohels, or similar 
lines marking the limits of equal extent of sunshine, and maps showing the 
paths of barometric minima. 
It may be mentioned as another characteristic fact that when the 
Atlas of Zoogeography did appear it contained even more than was 
promised in the prospectus — 36 instead of 35 plates. In this case the long
