Egypt was concerned, of a mere exclusion to the lower part of that valley which 
Mr. Wilherby has had the opportunity of following up farther towards the source 
of Old Nile ; but the earlier work compares, we think, favourably with the later 
in its more philosophical grasp of biological problems. It must, however, in 
fairness be stated that this is professedly a popular account written for the pages 
of our ever-interesting contemporary, and that the author has published further 
scientific details in the /fits. The route extended about two degrees south of 
Khartoum, and three new species of mammals, one bird, Cisticola aridula, and a 
flea, proved to be new to science, whilst nearly 150 species of birds— the main 
objects of the Journey — are recorded in an Appendix as having been observed. 
The snap-shots, not very well focussed, do not add much to the value of this 
slight but interesting sketch. 
Plant Relations, a first book of Botany, Second Edition, and Plant Structures, 
a second book of Botany. Both by I’rof. J. M. Coulter. Twentieth Century 
Text-books. Ilirschfeld Brothers. Price 6s. net, each. 
Some months ago we reviewed in these pages a text-book by Prof. Coulter, 
entitled Plant Studies, which is an amalgamation, in some 390 pages, of these 
two volumes, which contain about 260 and 335 pages respectively. We do not 
quite see how this was done, but we notice that the second of the two volumes 
now under review contains chapters on the food of plants, the evolution of sex, 
the flower, differentiation of tissues and physiology, which ate not in the abridg- 
ment. For secondary or high school work these volumes are admirably adapted, 
more especially from their wealth of excellent illustrations ; but they hardly reach 
what we would fain hope is the standard of our universities. Professor Coulter’s 
introduction of ecology or bionomics before anatomy, gives a freshness to his 
whole view of the science, which is most stimulating. 
A Text-Book of Geology. By Professor A P. Brigham. Same series, publishers 
and price. 
Consistently with the plan adopted by Professor Coulter, in his botanical 
works in this series, the author of this excellent and well illustrated text-book 
begins with the more obvious and attractive department of the science, viz., 
dynamics, which occupies 190 out of about 460 pages. Petrology is very briefly 
treated, geotectonics and physiography only a little less so, and palaeontology only 
incidentally in the historical portion, which occupies 173 pages. We should much 
like to see a larger work by the same author, in which the second, or as he terms 
it, “structural,” part should receive at least equal space to that accorded to 
dynamics and stratigraphy. The illustrations and the spelling, as in “ bowlder,” 
“paleozoic,” &c., are American; but this does not affect the value of the first 
part of the work to English students ; and, though by no means written down, it 
could well be used as a first book. 
/he Foraminifera : an Introduction to the Study of the Protozoa. By Frederick 
Chapman, A.L.S., F. R.M.S. With numerous illustrations. Longmans. 
Price 9s. net. 
It has seldom been our good fortune to come across so thorough and complete 
an introduction to the study of a large group of organisms as is this by no means 
large or expensive work. The history of our knowledge of the Foraminifera, 
their anatomy and physiology, a systematic account of all the genera, with 
mention of type species, an account of their range in time and in space, and of 
methods of collecting and examining, with a copious bibliography, and an Index 
which has the novel feature of including the specific names, make up an admir- 
able piece of work. Fortunately, Foraminifera lend themselves to inexpensive 
methods of illustration, so that we do not think that so heavily surfaced a paper 
need have been employed ; but this is our only complaint.

The third annual issue of this directory, so indispensable to all actively 
engaged in humanitarian work, contains summaries of recent legislation and 
other useful matter in a very handy form.
