[Footnote 19: At first sight Byron appears to refer to the lighting of streets by gas, especially as the first shop lighted with it was that of Lardner & Co., at the corner of the Albany (June, 1805), and as lamps were on view at the premises of the Gas Light and Coke Company in Pall Mall from 1808 onwards. But it is almost certain that he alludes to the "sublimating gas" of Dr. Beddoes, which his assistant, Davy, mentions in his 'Researches' (1800) as nitrous oxide, and which was used by Southey and Coleridge. The same four "wonders" of medical science are depicted in Gillray's caricatures, November, 1801, and May and June, 1802, and are satirized in Christopher Caustic's 'Terrible Tractoration! A Poetical Petition against Galvanising Trumpery and the Perkinistit Institution' (in 4 cantos, 1803). Against vaccination, or cow-pox, a brisk war was still being carried on. Gillray has a likeness of Jenner vaccinating patients. Metallic "Tractors" were a remedy much advertised at the beginning of the century by an American quack, Benjamin Charles Perkins, founder of the Perkinean Institution in London, as a "cure for all Disorders, Red Noses, Gouty Toes, Windy Bowels, Broken Legs, Hump Backs." In Galvanism several experiments, conducted by Professor Aldini, nephew of Galvani, are described in the 'Morning Post' for Jan. 6th, Feb. 6th, and Jan. 22nd, 1803. The latter were made on the body of Forster the murderer. For the allusion to Gas, compare 'Terrible Tractoration', canto 1-- "Beddoes (bless the good doctor) has Sent me a bag full of his gas, Which snuff'd the nose up, makes wit brighter, And eke a dunce an airy writer."] [Footnote 20: Stott, better known in the 'Morning Post' by the name of Hafiz. This personage is at present the most profound explorer of the bathos. I remember, when the reigning family left Portugal, a special Ode of Master Stott's, beginning thus:--('Stott loquitur quoad Hibernia')-- "Princely offspring of Braganza, Erin greets thee with a stanza," etc. Also a Sonnet to Rats, well worthy of the subject, and a most thundering Ode, commencing as follows:-- "Oh! for a Lay! loud as the surge That lashes Lapland's sounding shore." Lord have mercy on us! the "Lay of the Last Minstrel" was nothing to this. [The lines "Princely Offspring," headed "Extemporaneous Verse on the expulsion of the Prince Regent from Portugal by Gallic Tyranny," were published in the 'Morning Post', Dec. 30, 1807. (See 'post', l. 708, and 'note'.)] ] [Footnote 21: See p. 317, note 1.]
