This is an extensive paper upon the Bean Pod Spot (Colleto- 
trichum Lindemuthianum (S. & M.} B. & C)., giving the distribution 
and character of the disease and its appearance upon pods, leaves, 
seed and seedlings. Field experiments were made with fungicides, 
and comparisons of results are given in the chapter closing with a 
bibliography of the subject. 
Brief mention is added of a bacterial bean blight and of the 
Bean Rust (Uromyces Phaseoli (Pers.) Wint). Six full page plates 
are given. The same matter appears as Bull. 48 of the Geneva,

The New Botany. Lester F. Ward (Science, xxi. 43, 44). 
This article is in the nature of a plea for the more systematic 
study of plant affinities rather than plant differences. The author 
urges the necessity for the study of fossil plants in order that we 
may understand the ancestry of our living plants and how these 
came to be what we now find them. The mere determination of 
plants, either living or fossil, is of course necessary, but in order 
to appreciate fully what these determinations mean, a close study 
of their affinities is necessary, and this can only be done by a close 
comparison of living and fossil forms. A. H.
