Robert Fife, F.R.H.S.; together with a very complete list of varieties grown 
in 1896 and prognostigations as to its future, by William Cuthbertson. 
Although written with English conditions in mind there will be information of 
value to American cultivators.—C. R. B 
Boranists frequently find in literature reagents and reactions referred to 
by the names of their authors, and they are often at a loss to know what is 
meant. For such, a key is afforded by a recent reprint from the Pharmaceu- 
tical Review. Mr. Richard Fischer has translated Altschul’s list of reagents 
and reactions, about 600 in number, arranged alphabetically under their 
authors’ names, and followed by an index of subjects. The list contains a 
considerable number of physiological reagents and some of the more impor- 
tant bacteriological ones. Numerous cross references make consultation easy. 
The repaging of the pamphlet, an annoyance necessitated by the form of the 
journal from which it is reprinted, might have been partially counteracted 
somewhat by an indication in the margin of original pagination.— C. R. B 
A BACTERIAL DISEASE of the common squash-bug (Anasa tristis) has 
been studied by B. M. Duggar‘ at the Illinois State Laboratory. Itis readily 
communicated to chinch-bugs, and is the first genuine bacterial disease of 
hemipterous insects known. The Bacillus insectorum of Burrill, formerly 
classed as such, has been found to be a normal inhabitant of the ccecal 
appendages of many insects, and not pathogenic. The germ stains more 
deeply at the poles, but produces no spores. The growth on agar agar when 
added to water makes an infusion that is highly toxic to all classes of insects, 
killing them after a few minutes immersion. On account of this property 
the germ has been named Saci/lus entomotoxicon. Mr. Duggar gave some 
account of this work at the Buffalo meeting of the American Association, an 
abstract of which will be found in this journal.5—J. C. A 
Mr. A. J. McCLATCHIE has printed in the Proceedings of the Southern 
California Academy of Science® a list of the seedless plants known to occur in 
the coast region of southern California. The catalogue is preceded by a 
synopsis of the vegetable kingdom, in which are to be found some novelties 
in the way of classification, as also in the list itself. One thousand and
