His residence in so accessible a part of London did, however, expose him to the constant invasion of callers, and his own good nature often rendered fruitless the efforts that were considerately made to restrict these within reasonable limits. Of course he suffered from the curious and the inconsiderate of the human species; and then there were those pertinacious bores, the dabblers in science. "One morning a young man called on him, and with an air of great importance confided to him the result of some original researches (so he deemed them) in electrical philosophy. 'And pray,' asked the Professor, taking down a volume of Rees' Cyclopædia, 'did you consult this or any elementary work to learn whether your discovery had been anticipated?' The young man replied in the negative. 'Then why do you come to waste my time about well-known facts, that were published forty years ago?' 'Sir,' said the visitor, 'I thought I had better bring the matter to head-quarters immediately.' 'All very well for you, but not so well for head-quarters,' replied the Professor, sharply, and set him down to read the article." "A grave, elderly gentleman once waited upon him to submit to his notice 'a new law of physics.' The visitor requested that a jug of water and a tumbler might be brought, and then producing a cork, 'You will be pleased to observe,' said he, 'how persistently this cork clings to the side of the glass when the vessel is half filled.' 'Just so,' replied the Professor. 'But now,' resumed this great discoverer, 'mark what happens when I fill the tumbler to the brim. There! you see the cork flies to the centre--positively repelled by the sides!' 'Precisely so,' replied the amused electrician, with the air of a man who felt perfectly at home with the phenomenon, and indeed regarded it quite as an old friend. The visitor was evidently disconcerted. 'Pray how long have you known this?' he ventured to ask Faraday. 'Oh, ever since I was a boy,' was the rejoinder. Crestfallen--his discovery demolished in a moment--the poor gentleman was retiring with many apologies, when the Professor, sincerely concerned at his disappointment, comforted him by suggesting that possibly he might some day alight upon something really new."[8] But there were other visitors who were right welcome to a portion of his time. One day it might be a young man, whom a few kind words and a little attention on the part of the great philosopher would send forward on the journey of life with new energy and hopes. Another day it might be some intellectual chieftain, who could meet the prince of experimenters on equal terms. But these are hardly to be regarded as interruptions;--rather as a part of his chosen work.
