The plan of a text-book in microbiology, which seeks to furnish 
basic principles, must assume a definite and systematic arrange- 
ment. With this in view, the text, amply illustrated with figures, 
has been divided into three parts: Morphological and Cultural, 
or that which deals with lower forms of life and methods of 
handling; Physiological, or that which deals strictly with func- 
tions; Applied, or that which reaches into the application of the 
facts developed to the problems met in the study of professional 
or practical affairs of agriculture, or domestic science.—]oHN

We learn from Science that under the auspices of the Geo- 
graphical Society of Philadelphia, a botanic and geographic 
expedition is to be made this summer to southern Florida by Pro- 
fessor John W. Harshberger, of the University of Pennsylvania. 
Professor Harshberger has made two previous trips to Florida 
and this expedition is to complete his studies in the Everglades 
region of the extreme southern part of the peninsula. The 
itinerary will be approximately as follows: Making Fort Meyers 
on the west coast headquarters, Professor Harshberger will first 
investigate the region in that vicinity; visits will be made to 
several of the islands along the gulf coast: the Caloosahatche will 
be ascended by power boat to Lake Okeechobee and the flora 
of that inland lake will be studied. Then the attempt will be 
made (if the drainage canal has been sufficiently constructed) 
to cross the Everglades to Fort Lauderdale on the east coast. 
As no botanical geographer has ever crossed the Everglades, 
unusual opportunities will be presented to study a region of great 
scientific interest, Photographs will be taken of the vegetation, 
the region will be mapped botanically, and a collection of the 
more interesting plants will be made. An abstract of the results 
of this expedition will be published in the October number of 
the Bulletin of the Geographical Society of Philadelphia, 
The United' States Forest Service has prepared a traveling 
exhibit of photographs for circulation among schools and libraries. 
It is sent free of expense, except of course transportation charges
