Bordeaux Mixture which under orchard conditions is of fungi¬ 
cidal value, is chiefly accomplished by the solvent action of the 
fungous spores themselves, for they have power to dissolve suf¬ 
ficient copper to kill themselves.” 
In the Botaniska Notiser for 1902 (pp. 113-128 & 
161-179) Tycho Vestergren gives a “Verzeichniss nebst Diagno- 
sen und Kritischen Bemerkungen zu meinem Exsiccatenwerke, 
Micromycetes rariores selecti,” Fasc. 11-17. A dozen new species 
are described. 
The article by David Griffiths, concerning some West 
American Fungi, Bull. Torr. Bot. Club, 29: 290-301, May 1902, 
deals with seventeen parasitic fungi belonging to the genera 
Tilletia, Ustilago, Sorosporium, Gymnoconia, Puccinia, Aecid- 
ium, and Claviceps ( ?) ; twelve of the species are described and 
named as new to science. 
In Science, (N. S. 16: 434-5) Sept. 12, 1902, P. J. O’Gara 
gives some Notes on Canker and Black-Rot,, the former on 
Rhus glabra caused by Sphaeropsis rhoina (Schw.) Starb. In- 
completed experiments are reported to determine whether Sphae¬ 
ropsis rhoina of the Sumac and Sphaeropsis of the apple may not 
be the same. The facts already established “go to show that 
Sphaeropsis rhoina will cause black-rot in the fruit of the apple 
and will also produce the typical ‘canker’ on the branches and 
limbs just as readily as Sphaeropsis malorum. Although the 
evidence is not complete it is probable that the two species are 
identical.” 
An Abstract of a paper by Dr. V. C. Vaughan on the 
Nature O'f the specific Bacterial Toxins is given in Science, N. S. 
16: 312-5, Aug. 22, 1902. 
A list of Bar Harbor (Mt. Desert) Fungi, about 255 in 
number is given by V. S. White, Bull. Torr. Bot. Club, 29:550- 
563, Sept. 1902. Most of the interesting list are the higher fungi 
— eight of which are new species, six by Peck and two by 
Banker. The starred species, 120 in number, are not found in 
Ricker’s List of Maine Fungi (April 1902). 
The prevention of Molds on Cigars, by Rodney H. True, 
is a short article in Science, N. S. 16: 115-6, July 18, 1902, in 
which it is shown that this affection pertains only to cigars whose 
wrapper-leaf has been treated with tragacanth paste, and is pre¬ 
ventable by making the latter with a saturated solution of boracic 
acid instead of water. 
Investigations on a Bacterial Soft-Rot of certain Cruci¬ 
ferous Plants and Amorphophallus simlense by H. A. Harding 
and F. C. Stewart are reported in Science, N. S. 16: 314-5, Aug. 
22, 1902.
