Ms transcripts of other papers published in the Philosophical Magazine but not dated: On the Speed of signalling through heterogeneous telegraph circuits; On Electromagnets in Telegraphy; On Duplex Telegraphy II January 1875. Printed copies of 'On the Best Arrangement of Wheatstone's Bridge for measuring a given resistance with a given galvanometer and battery', printed in the Philosphical Magazine February 1873; and On an Advantageous method of using the differential galvanometer for measuring small resistances' printed in the Philosphical Magazine April 1873. Ms transcript of Sensitiveness of Wheatstone's Bridge, published in the Electrician, not dated. All with additional notes and calculations on the left side pages, headed Notes on the Bridge and Differential Duplexes; Disturbances produced by variation of the resistance of the line; Short Circuit; Comparisons Duplex and Single Working; Experimental results of AWH (Arthur Heaviside, Oliver's brother and a leading telegraph engineer) referred to in the text; Currents in all branches; Special cases mentioned in text; On the Differential Galvanometer; The divided battery balances and their duplexes. At rear of volume is distribution list for several of Heaviside's works with names and addresses of recipients, including Oliver Lodge, G F Fitzgerald, Hertz, Lord Rayleigh, Lord Kelvin, Helmholtz and other eminents scientists of the time in Europe, America and Australia.
