The author played an important part in the French Revol ition ; he was elected President of the National Assembly on 

 June 17th, 1789, and Mayor of Paris the same year, but tinally fell a victim to the mob, and was guillotined in 1793, after 

 the usual Jacobin insults, which made Carlyle exclaim : ' Crueller end had no mortal.' 



5941 BAIN (Alexander) ACCOUNT of some REMARKABLE APPLICATIONS of the ELECTRIC FLUID to 

 the USEFUL ARTS ; with a Vindication of his CLAIM to be FIRST INVENTOR of the ELECTRO- 

 MAGNETIC PRINTING TELEGRAPH, and also of the ELECTRO-MAGNETIC CLOCK, by JOHN 

 FINLAISON, Actuary of the National Debt Office, with 5 large folding plates, post 8vo. sewn, with 

 inscr. to Earl Russell (VERY SCARCE), 1.1* 1843 



' To the Right Honourable The Lord John Russell with the author's most respectful compliments.' Inscr. on flyleaf. 



The inventor was a Caithnessshire man, and apparently no connexion of his contemporary namesake the Rector of 

 Aberdeen University. 



' He was one of the tirst to devise a method by which a number of clocks could be worked electrically from a standard 

 time keeper . . . He discovered independently the use of the earth circuit. Electric fire-alarms and sounding apparatus 

 were also among his inventions. His most important invention was the chemical telegraph of 1843. This apparatus 

 could be worked at a speed hitherto imnossible, and its invention certainly entitles Bain to the credit of being the pioneer 

 of modern high-speed telegraphy . . . Perhaps the most valuable part of the invention consisted in the use of strips of 

 perforated paper for the transmission of the message. This contrivance was long after adopted by Wheatstone, and is in 

 use in all the existing high-speed systems of telegraphy.' D. Af. B.

 Degree, and the finding of all their Roots, as well false, as true ; without the use of Mesolabe, 

 Trisection of Angles, Reduction, Depression, or any other previous preparation of Equations, 

 by a Circle, and any (and that but one only) Parabole. And this, by one only General 

 Rule ; than which a more simple, more perfect, more general, more easie to be understood, or 

 more fit for practice, cannot be devised or wished for ; with Demonstrations, Figures, etc. etc.

"The leading idea of Baker's work is the solution of biquadratic equations (and those of a lower degree) by a geometrical 

 construction, a parabola intersected by a circle. The method is distinguished from that of Descartes by not requiring the 

 equation to be previously deprived of its second term. The general principle is worked out in great detail. . . . Some 

 account of the work is given in the Transactions of the Royal Society.' D. N. B.

' He suggests balloon geography, in which maps should be drawn with a camera obscura, aided by a micrometer applied 

 to the underside of the transparent glass ; and notices the predilection balloons have for becoming stationary, even in a 

 strong gale, over channels and rivers'. Hatton Tumor.
