bulletin no. 27 from the N. Dakota Experiment Station. Two very interest- 
ing articles are “‘ Twenty years progress in pathology”’ by B. T. Galloway, 
and “ The botanic garden as an aid to agriculture” by William Trelease.—

A NEW LABORATORY GUIDE for bacteriology by Mr. W. D. Frost, of the 
University of Wisconsin, is a convenient combination of directions for exper- 
iments, blank pages, charts, and outline drawings in which results may be 
recorded, together with some general information.9 
e first part of the book is devoted to general bacteriology with the 
usual description of technique and laboratory methods. The medical part of 
the book is more complete than usual for an elementary text book. 
General information is given in the form of brief notes wherever a germ 
is mentioned for study, relating its source, time of isolation and discoverer, 
with references to the original and other descriptions. A chapter on tax- 
onomy includes Chester’s scheme of nomenclature of cultural characters and 
Migula’s valuable classification of bacteria. 
he most striking features of the book are the well-outlined and system- 
atic arrangement of material, and the unusual and deserved attention given 
to one of the most important problems in the study of bacteria today, the 
effect of environmental action. The chart blanks are excellently designed for 
the record of the numerous physiological and morphological characters of a 
culture under study. A useful supplement to these detailed record blanks 
would be a few charts such as those recommended by Fuller for recording 
definite position and negation reactions in comparative form. The book as 
it stands, however, is’very complete and will be welcomed in many labora- 
tories— Mary HEFFERAN. 
NOTES FOR STUDENTS: 
THE great prevalence of potato blight (PAylophthora infestans) in the state 
of Washington for the past two years has led to the publication of a bulletin” 
on the subject by the Agricultural Experiment Station, based on experiments 
made at the Puyallup station. Bordeaux mixture applied before the disease 
began to be apparent and again after about two weeks was found to decrease 
materially the injury from the disease.— ERNsT A. BESSEY. 
PROFESSOR Conway MacMILLAN has been studying the growth perio- 
dicity of the potato tuber™ by the method described in this journal (16: 149. 
1891) which he has improved upon by employing a second wheel to magnify
