 on the Rating of Gas-Mains, and a Note on the Electric-Light, Bvo. sewn {scarce), Qs 1849 



Especially interesting for the note, which is probably one of the earliest references to electric lighting. The author 

 mentions that 'about six years since it was shown in the streets of Paris, where, for a short time, it excited as much 

 attention as it has lately done in this country.' The current of course was produced by a galvanic battery, and the con- 

 tinuous adjustment of the carbon points then proved an insuperable practical difficulty.

front., and woodcuts, cr. 8vo. cl., 4s 1854 



• My special object has been to invite attention to electricity in its various relations with vitality. This is no longer a 

 topic for vague speculations or uncertain conjectures,' etc. etc. — Preface,.

 Ships, in Order that their respective Duties may be performed with the least possible Consumption 

 of Fuel, with diagrams, and folding table, 8vo. cl., 5s Qd 1852 



The work was unknown to the author's biographer in D. N. B. There were not many steamships in the Navy in 1852 I 

 and those nearly all paddle-boats, with masts and sails, and the multifarious methods of wasting coal here denounced are 

 very curious. Admiral Ryder of course urges working expansively.
