interesting, and promises that when fully installed it will be one of the 
most instructive gardens in the Western Hemisphere. 
In a recent number of Garden and Forest (January 13), Professor 
Card makes a strong plea for experimental plant physiology as an ad- 
junct to instruction in modern horticulture. It will repay reading by 
all botanists, and should encourage the introduction of physiological 
work in agricultural colleges, where it has generally been neglected, as 
well as in the larger universities where it has already had some recog- 
nition. 
Professor Hitchcock’s bulletin (62) on Corn Smut, issued by the 
Kansas Experiment Station, gives, in addition to much relating to 
structure and the germination of the spores, an extended synonymy 
and bibliography. He concludes, rather hastily, we think, that the 
name under which this smut be known is Ustilago mays zeae (DC) 
Magnus (= Uredo segetum var. mays zeae DCO, Fl. Fr., If, 1805, = 
Uredo maydis DC. FI. Fr., VI, 1815). De Candolle himself did not 
consider that he had sufficiently designated it in Vol. II of “ Flora 
Francaise,” since, in Vol. VI, he does not refer to his note in the earlier 
volume, but proceeds to describe it as a distinct species under the name 
Uredo maydis. We should not now compel De Candolle to say in 1805 
what, ten years later, he himself felt that he had not said. 
Another little book has appeared from the facile pen of Professor L. 
H. Bailey, which is, incidentally,.of considerable interest to botanists, 
although primarily designed for gardeners. Under the title, “The 
Forcing Book” (The Macmillan Company), he tells much about green- 
house construction, heating and management, which will be most use- 
ful to those botanists who possess, or hope to build, a plant-house. The 
chapters on Lettuce, Cauliflower, Radishes, Tomatoes, Cucumbers, etc., 
are admirable illustrations of clear presentations, and will be valuable 
to botanists as well as gardeners—CuAr.ues E. Bessey. 
ZOOLOGY. 
Paramceba eilhardii.'—The ameboid organism to which Dr. Fr. 
Schaundinn gives this new specific and generic name was found by him 
in the salt-water aquarium of the Berlin Zoological Institute. Its 
life history was found to consist of three stages. (1) An ameeboid 
stage, in which the organism measures from 10-90» microns, is disc-
