14420 RONALDS (Sir Francis, F.R.S. ; inventor, in 1816, of the electric telegraph) DESCRIPTIONS of 

 an ELECTRICAL TELEGRAPH, and of some other Electrical Apparatus, 2nd "Edition [with PREFACE], 

 with 4 plates (one folding) of the installation and the electrical apparatus used, 8vo. cl. (SCARCE), 

 125 6d 1871 



This work contains the account, of the electric telegraph invented by the author, which transmitted signals from his 

 house at Hammersmith (occupied later on by WILLIAM MORRIS, the poet, and known as ' Kelrnscott House ') over a system 

 of wires 8 miles long, by observing at one end the divergence of a pair of pith balls when a charge of electricity was sent 

 into the other. 



' Ronalds's instrument was of real practical use, and the brilliant idea of using synchronously rotating discs, now 

 employed in the Hughes printing apparatus, was entirely his own. The only defect in his invention was the comparative 

 slowness with which a succession of symbols could be transmitted'. D. N. B. He at once offered the invention to the 

 Admiralty, and was officially answered that now the French war was over telegraphs of any kind were wholly needless, 

 and that no other than the semaphore then in use would be adopted. The inventor published the above account first iu 

 1823, and then dropped telegraphy for good. 



This second edition contains an interesting preface dated Battle, Oct. 9, 1871, and written in the inventor's 83rd year 

 and 48 years after the publication of the first edition. There are however only 4 plates, instead of the 8 contained in the 

 original edition. 



It is pleasing to remember that an Englishman, DR. WILLIAM GILBERT, wrote the first scientific treatise on electricity 

 in Elizabeth's reign, and another invented the electric telegraph in George the Third's, and another wireless telegraphy 

 (on the Flat Holm in the Bristol Channel) in Queen Victoria's. 



14421 RONAYNE (Philip) TREATISE of ALGEBRA, in two Books, the First treating of the 

 ARITHMETICAL, the Second of the GEOMETRICAL PART ; 2nd Edition, with Additions, numerous 

 diagrams, 8vo. old calf, 8s 6d 1727 



This work was unknown to Poggendorff (who does not even mention the author), Lowndes, and Allibone. Pp. 395-461 

 treat of the obsolete METHOD of EXHAUSTION, with applications to draw tangents, to find the maxima and minima of 

 curves, aad to quadratures, yet the author does not even remotely refer to Newton's Method of Fluxions, or the principles 

 underlying it. The author was doubtless an ancestor of Joseph Philip Ronayne, railway and hydraulic engineer in 

 Ireland and California, and Home Rule M.P., who died in 1876.

This is probably the only complete work ever written on this interesting subject, and fully discusses the ships of 

 many-banked oars which must have added a horror of their own to the slavery of a cultured Antiquity. There was no 

 copy of the work in the Scott Library, nor is there one in that of the Institution of Naval Architects.
