NEW SCIENTIFIC INSTRUMENT FACTORY. | 
WE beg to announce that owing to increase of business | 
we have found it necessary to start a New Factory at 
i LIDGE JAMES STREET, W.c. 
where our well known ‘* Apps-Newton ” 
Multiple-plate Wimshurst Electrical Machines for 
work and Wireless Telegraphy will in future be manufactured, 
as well as the Scientific Instruments and 
Apparatus which we now make so largely. 
Our Optical Lanterns will still continue to be manufactured 
at-our Fleet Street workshops, and. the Lantern Slides at our 
Dalston and Islington works as heretofore. 
The different floors of the New Factory have been carefully 
arranged for securing a large output, and Electric Motive Power 
is being fitted to the machine tools, so that we shall hope to 
execute orders more expeditiously in future ; and every effort 
will be made to sustain and improve the reputation of the 
Firm for thoroughly sound and accurate: Wi orkmanship.
