of new species of plants, chiefly from our Western Territories. 
The first includes the “ Polypetala” only, and is much more than 
a list, containing descriptions of many species, and notes upon 
many others. 
all uncomfortably warm. 
The botanical part of the course, under Mr. J. C. Arthur, con- 
sisted of lectures, laboratory work, and collecting excursions. 
The botanical laboratory, supplied with simple and compound 
microscopes, was open from 9.30 A. M. to 6 P.M. Forty students 
availed themselves of its privileges. 
A small part of the time was given to the study of plants with 
no other aid than the gommon hand lens. Besides illustrating a 
method of careful observation, it was designed to show that in- 
struction need not be confined to flowering plants because a com- 
pound microscope is not obtainable. For this purpose four plants 
were used: dark green scum (Oscillatoria), large tree lichen (Par- 
melia), common liverwort (Marchantia), and milkweed (Asclepias 
cornuti). ; 
The work with the compound microscope covered in the main 
the same ground as the lectures, which were as follows: 1. A sur- 
vey of the science; 2. Protoplasm; 3. The cell, and cell-structures : 
4. Protophyta, the sexless plants; 5. Zygosporez, the unisexual 
plants; 6. Oosporez, the egg-sporé plants; 7 and 8. Carposporee, 
the red sea-weeds and their allies; 9. Bryophyta, the mosses and 
liverworts ; Pteridophyta, the ferns and their allies; 11: Phanero- 
gamia, the seed-bearing plants, (1) the conifers and their allies ; 
12. Same, (11) the flowering plants proper; 13. General histology 
Of tissues ; 14. Movement of water and gases in the plant; 15. 
Assimilation and metastasis; 16. Movements of plants; 17. Modes 
of fertilization; 18. Dissemination of seeds; 19. Insectivorous 
plants. 
_ SYLLOGE FUNGORUM OMNIUM HUCUSQUE COGNITORUM. By Profes- 
sor P. A. Saccardo, Padova, Italy.—The first volume of this long 
expected work has at length appeared and will help to satisfy a 
want that has long been felt by the students of mycology. The 
volume forms a large octavo of 768 pages, with descriptions of 
nearly 2900 species of Sphzriceous Fungi. Adding greatly to 
the practical value of the work are the haditat lists inserted after 
each of the different families or sub-divisions and giving in alpha- 
grow, with numbers referring to the descriptions of the species 
found on each. The low price (49 francs) at which the volume is
