Price rs. 6d., post free rs. od. 
The object of Mr. O. G. Pritchard in preparing this work for publication was to enable 
British manufacturers to compete with those of Frauce, Austria, Germany and Bohemia in the 
Production of electric arc carbon candles. The book is fully illustrated and gives technical 
details for the establishment and working of a complete carbon factory.

ELECTRICITY IN MINES.—Under the new Rules and Regula- 
tions concerning the Use of Electricity in Mining Operations, it is compulsory that 
directions for the effective Treatment of Cases of Apparent Death from Electric Shock be 
conspicuously placed in certain prescribed positions in the Mines. 
A set of these DIRECTIONS, with illustrations showing the method of their application, 
accompanied by PRECAUTIONS to be adopted to prevent danger from the electric current, 
can be supplied. .

“THE ELECTRICIAN” PRIMERS. (Fully Illustrated.) A Series 
of Helpful Primers on Electrical Subjects for the Use of those seeking a Knowledge of 
Electricity—Theoretical and Practical. Newand Greatly Enlarged Edition in Preparation. 
‘“‘ The Electrician”? Primers were originally published in 1891 and had a large sale. They 
were published with the object of meeting the demand for a correctly-written series of scientific 
leaflets on the Theory and Practice of Electricity to replace the inaccurate and misleading 
pamphlets and eh la pi articles which were then being issued broadcast, and which it was 
telt were calculated to do much harm to students and others who consulted them for information 
concerning electrotechnical subjects. . 
In this way ‘The Electrician” Primers met a real want, The great advances made in 
Electrical Science and Practice have now demanded the complete revision of the ‘‘ Primers,” 
and their extension to embrace the numerous additional subjects which come within the range 
of the studies of the student and others seeking a knowledge of Electricity—Theoretical and 
Practical. i 
The New Edition will, therefore, be entirely rewritten to bring. the original Papers up to 
date, and the number of Primers will be greatly extended, embracing all additional subjects 
which have come to the front since the first edition was published. This will necessitate three 
Volumes. Vol. I. will, as before, be devoted to “‘ Theory,” and will consist of about 23 Primers; 
Vol. II. will treat of ‘‘ Practice,” in relation to Engineering (about 20 Primers); and Vol. III. to 
the lighter branches, Telegraphy, Telephony, Electro-Chemistry, Electro-Metallurgy, Electro- 
Therapy, and Miscellaneous.
