European investigators like Dr. Fisher may still be in 
doubt as to the correctness of the conclusions arrived at by 
Dr. Smith, those who are familiar with his work know how 
thoroughly and carefully it has been done can not doubt 
the general status of this question as regards diseases pro- 
duced by bacteria. The papers are commended for a care- 
ful perusal by those who are interested in getting an insight 
into this important question. (Centralblatt f Bakt. u. Par- 
asitenk. II Abt. 5: 271, 279, 810. 7: 88, 128, 190.) 
Nuciear Division In Furico Varians.—Prof. W. A. 
Harper does not agree with Rosell that there are two dif- 
ferent kinds of nuclei in this plant. These differences are 
due to inequalities of fixation. Karyokinetic figures can 
be found oriented in all possible ways to the cleavage fur- 
rows. (Bot. Gazette 30: 218.) 
PaTHogENic AsPERGILLI.—Dr. T. A. Rothwell has made 
experiments with A. niger and A. fumigatus, both are patho- 
genic but the A. fumigatus may produce death and A. niger 
never did in his experiments. 
Botany Durine THE NINETEENTH CENTURY.—The St. 
Louis Academy of Science is devoting a series of meetings 
to discussing the progress made in science. This subject 
was treated by Dr. Trelease of the Missouri Botanical Gar- 
den. Though necessarily treated somewhat concisely, he 
presented it in a lucid and brief manner as one only can 
who is familiar with every phase of the subject. The topics 
discussed are systematic botany, systems of classification, 
evolution and classification, morphology and anatomy, phys- 
iology, protoplasm, ecology, applied botany, popularization 
and publication, botany in the United States. cee Acad. 
Sci. St. Louis, 11: 125-142.) 
Fusarium Equinum.—Victor A. Novgard describes a 
new species of Fusarium that is causing an epidemic skin 
disease of horses on the Umatilla Indian Reservation. More 
than 60 per cent of the 6,000 horses on the reservation are
