Fleming—A HANDBOOK FOR THE ELECTRICAL LAB- 
ORATORY AND TESTING ROOM. By Dr. J. A. Fleming, M.A., F.R.S.,M.R.L., 
&c. Vol. I., price ras. 6d. nett, post free 13s. Vol. II. x4s. nett. 
, This Handbook has been written especially to meet the requirements of Electrical 
Engineers in Supply Stations, Electrical Factories and Testing Rooms. The Book consists of a 
series of Chapters each describing the most approved and practical methods of conducting some 
one class of Electrical Measurements, such as those of Resistance, Electromotive Force, Current, 
‘ower, &c., &e. It does not contain merely an indiscriminate collection ot Physical Laboratory, 
processes without regard to suitability for Engineering Work. The Author has brought to 
its compilation a long practical experience of the methods described, and it will be found to be a 
digest of the best experience in Electrical Testing. The Volumes contain a Chapter on the 
Equipment of £lectrical Laboratories and numerous Tables of Electrical Data, which will render 
it an essential addition to the library of every practical Electrician, Teacher or Student.

Fleming—ELECTRICAL LABORATORY NOTES AND FORMS. 
Arranged and prepared by Dr. J. A. Fleming, M.A., F.R.S., Professor of Electrical 
Engineering in University College, London. 
These ‘‘ Laboratory Notes and Forms” have been prepared to assist Teachers, Demonstra- 
tors, and Students in Electrical Laboratories, and to enable the Teacher to economise time. They 
consist of a series of (about) Twenty Elementary and (about) Twenty Advanced Exercises in 
Practical Electrical Measurements and Testing. Foreach of these Exercises a four-page Report 
Sheet has been prepared, two pages of which are occupied with a condensed account of the theory 
and practical instructions for performing the particular Experiment, the two other pages being 
ruled up in lettered columns, to be filled in by the Student with the observed and calculated 
uantities. When simple diagrams will assist the Student, these have been supplied. These 
xercises are for the most part based on the methods in use in the Electrical Engineering 
Laboratories of University College, London; but they are perfectly general, and can be put into 
practice in any Electrical Laboratory. 
Each Form is supplied either singly at 4d. nett, or at 3s. 6d. per dozen nett (assorted or 
otherwise as required) ; in sets of any three at 1s. nett ; or the set of (about) Twenty Elementary 
(or Advanced) Exercises can be obtained, price 5s, 6d. nett. The complete set of Elementary and 
Advanced Exercises are price ros. 6d. nett, or in a handy Portfolio, rzs. nett, or bound in strong 
cloth case, price 12s. 6d. nett. 
Spare Tabulated Sheets for Observations, price 1d. each nett. 
Strong Portfolios, price 1s. 6d. each. ‘ 
The very best quality foolscap sectional paper (16in. by 13in.) can be supplied, price 1s. per 
dozen sheets nett. 
NOW READY.—Cheaper edition of ‘‘ Electrical Laboratory Notes and Forms.” These 
cheaper Forms have been prepared for the use of students and teachers at the Polytechnic and . 
other science classes throughout the country. These new Forms, which differ only from the higher 
priced set in being printed on smaller and cheaper paper and with less space for tabulated records, 
are issued at half the price of the above set. Bound in strong case, 7s. 6d. 
Fleming.—ELECTRIC LAMPS AND ELECTRIC LIGHTING. 
By Prof, J. A. Fleming, M.A., D.Sc., F.R.S., M.R.I., Professor of Electrical Engineer, 
ing in University College, London. New and Cheaper Edition. Very fully illustrated- 
handsomely bound, on good paper, price 6s. nett. 
The original aim of a course ot four lectures by Prof. J. A. Fleming on “ Electric Illumina- 
tion ” was to offer to a general audience such non-technical explanations of the physical effects 
and problems concerned in the modern applications of electricity for illumination purposes as 
might serve to further an intelligent interest in the subject. In this, the second edition of the 
book, the author has brought the original edition into line with recent practice without departing 
from the elementary character of the work. 
Fleming—THE ALTERNATE CURRENT -TRANSFORMER 
IN THEORY AND PRACTICE, By J. A. Fleming, M.A., D.Sc., F.R.S., M.R.L, 
&c., Professor of Electrical Engineering in University College, London, New Edition— 
Almost entirely Rewritten, and brought up to date. More than 600 pages and 213 
illustrations, 12s. 6d. post free ; abroad 13s. 
Since the first edition of this Treatise was published, the study of the properties and appli- 
cations of alternating electric currents has made enormous progress. . . . . The Author has, 
accordingly, réwritten the greater part of the chapters, and availed himself of various criticisms, 
with the desire of removing mistakes and remedying defects of treatment. In the hope that this
