394 BOTANICAL GAZETTE [May 
made up of the beginning of an enumeration of some of the recently collected 
plants of Ahern, Jagor, Loher, Merrill, Warburg, and others; and the novelties 
are very numerous, the region promising to equal any other in the world in this 
regard. The Leguminosae (7 n. spp.), Dipterocarpaceae (2 n. spp.), Anacar- 
diaceae (8 n. spp.), Meliaceae (4 n. spp.), Pinaceae, and Taxaceae are by Dr. 
Perkins; Symplocaceae (1 n. sp.) by A. Brand; Acanthaceae by G. Lindau; 
Fagaceae by O. von Seemen; Typhaceae by P. Graebner; Orchidaceae by 
R. Schlechter; Palmae (6 n. spp.) by O. Beccari; Myristicaceae (1 n. sp.), 
Pandanaceae (1 n. sp.), and Begoniaceae (Io n. = ) by O. Warburg; and 
Sapindaceae (10 n. spp.) by L. Radlkofer.—J. M 
IN A LITTLE WORK intended for beginners, oe gives a detailed 
account of the processes of elementary photomicrography and lantern-slide 
making. The book is intended for those who have little or no knowledge of 
general photography, and presupposes that the learner will have a student 
microscope and field camera. After chapters on microscopes and optical 
apparatus, cameras and appliances, and various radiants (among which he 
justly gives a high place to acetylene), the various processes for medium and 
low power photography receive minute attention. For work of little amplifi- 
cation the use of short-focus photographic lenses is recommended, but the 
experienced worker, acquainted with modern lenses, wonders why a “rapid 
rectilinear” is advocated for such work. A table giving radiant, amplifica- 
SS time of exposure, etc., is of value to those who have had little experience.

THE FIFTH PART OF Rotn’s Eurofdischen Laubmoose, completing the 
first volume, has appeared. The volume contains 24 families of cleisto- 
carpic and acrocarpic mosses, the Bryaceae beginning the second volume. 
Corrections and additions occupy 12 pages. e described species and the 
_ synonyms are listed, unfortunately, in two indexes, printed alike and with no 
page heading to distinguish them. These editorial and typographical faults 
will cause much inconvenience in using the book, partly defeating the author's 
laudable desire to save his fellows time in determining the mosses. From 
the preface we learn that in case the work meets the approval of bryologists 
the author contemplates publishing his labors on exotic species, of which he 
has already nearly 3000 drawn.—C. R
