In the 6oth Bulletin of the Bureau of Plant In¬ 
dustry, U. S. Department of Agriculture, by C. O. Townsend, 
issued June 30, 1904, the title of which is A soft Rot of the 
Calla Lily, we learn that the fomenter of the disease is a hitherto 
undescribed bacterium, namely, Bacillus aroideae Townsend n. 
sp. It was isolated from rotting Calla corms and is the cause 
of a soft rot of the corm, petiole, and flower stalk of the Calla. 
It also causes — says the author — a soft, dark colored rot when 
inoculated into many raw vegetables, such as carrot, potatoe, 
turnip, radish, cabbage, and cauliflower. It also causes a soft 
rot of certain green fruits, such as tomatoe, egg plant, and cu¬ 
cumber. There are text figures by way of illustration in addi¬ 
tion to nine full page half tone plates. 
E. Rostrup gives in a 44-page reprint [Videnskabs-Selska- 
bets Skrifter, I, Math.-naturv. kl. 1904, No. 4] the Norske Asco- 
mycetes , with localities and hosts. Nearly two dozen new species 
are described lingua latina. 
To THE MANY SPECIES OF ASPERGILLUS AFFECTING FRUITS, 
G. Lindau in Hedwigia, Band 43, Heft 5, p. 306-7, adds yet 
another, namely, Aspergillus (Sterigmatocystis) strychni Lindau 
n. sp. Die neue Art unterscheidet sich von den bisher bekannten 
durch die riesenhaften Dimensionen der Konidientraeger und die 
Sterigmen. 
Investigations of Rusts by Mark Alfred Carleton, is 
an interesting Bulletin (No. 63) of the U. S. Department of 
Agriculture, Bureau of Plant Industry, issued July 12, 1904. 
Notes are given on life histories of Euphorbia Rust, Sunflower 
Rust, Crown Rust of Oats, supplementing and corroborating pre¬ 
vious published reports; also experiments with Puccinia xanthii 
Schw. and P. heterospora. The other topics are Segregation of 
host plants, Winter resistence of Uredo (of P. poarum Niels, 
and P. montanensis Ell.), Emergency adaptations (P. vexans 
Farl.), and Perennial species (Aecidium tuberculatum E. & K., 
and the rust on Peucedanum foeniculatum). Colored plates are 
given of Aecidium tuberculatum and of the Euphorbia Rust and 
Puccinia vexans. 
The Effect of Chemical Irritation on the Respira¬ 
tion has been experimentally investigated by Ada Watterson, 
whose report is found in the Bulletin of the Torrey Botanical 
Club for May 1904, pp. 291-303. She outlines the work of pre¬ 
vious investigators and summarizes the results quoted: we find 
that small quantities of certain poisonous substances act as stim¬ 
ulants, increasing the growth of certain plants; they also in¬ 
crease respiration, but what relation the latter increase bears to 
the former is not determined. In case of fungi stimulatio*
