REVIEW OF N. G. DROZDOV'S BOOK "STATIC ELECTRICITY IN INDUSTRY"
The use of modern high-speed machines and new materials has given rise
to a number of problems connected with static electricity. In these circum-
stances static electricity often sets up fields of considerable intensity,
produces silent or spark discharges, and causes the combustion of`,coal or other
inflammable gases. It also causes sheets of paper in paper mills and printing
presses to curl up, and affects motor and aviation transport.
The monograph under review examines the effects of static electricity in
industry. The author was one of the first to make a study of this somewhat
neglected field. He gives a detailed analysis of electro-static effects on
belt-driven machines and considers these effects in the rubber industry, in
textile enterprises and paper mills, in the electrification of compressed gases,
and in motor and aviation transport.
In the section dealing with the electrification of aerosols, the author
considers the possibility of combustion occurring in mixtures of coal dust,
gunpowder, and other friable materials. In the section on the electrification
of liquids, he describes effects relating to the use of gasoline, ether, and
other inflammable liquids. He concludes with a short summary of protective
measures, a description of new instruments for studying frictional electricity
and weak electric fields, and some remarks on the theory of the electrostatic
effects described in the book.
It is clear that this monograph is of interest both as an attempt to
make a theoretical study of static electricity and as a summary of data of
purely practical value. The author found it necessary to compress a large
amount of factual material into a comparatively small book, 175 pp, which
has resulted in a very broad approach. It would, have been better if basic

theory had been treated in greater detail. For example, the section entitled
schematic,, and hesauof the thor's conclusions are therefore stated rather n
developed.
The new instruments for studying frictional electricity and weak elec-
tric fields are of great interest, but even this section is so brief and
schematic that the uninitiated reader is unable to get a true picture of the
nature
and statici
the dis-
elation between the n electric state of the atmosphere insufficient
charges.
It would have been useful to point out that a string electrometer can
be used when more suitable instruments are not available. The author rec-
ommends the use of a galvanometer with a sensitivity of 10" a/mm (P 13),
but this would hardly be sensitive enough for this class of measurements.
To sum up, the monograph will be useful, and it is hoped that the theo-
retical part of the book will be dealt with more fully in a later edition.
