The first was tried on the 21st October, 1815; the second was tried on the 4th November; but it was not until the 9th November that Sir Humphry Davy presented his first lamp to the public. And by the 30th of the same month, as we have seen, Stephenson had constructed and tested his third safety-lamp.
Yesterday, when I came down to breakfast, I found Sir Humphry with a countenance radiant with pleasure, and eager to tell me that Captain Parry is to be sent out upon a new Polar expedition. August 14. This day, my dearest aunt, our wishes have been accomplished the sacred, awful vow has been pronounced, and Harriet and Mr. Edgeworth, married the Rev.
The expert had suggested a general research board to correlate researches; the professor cited the cases of Airy, the astronomer royal of England, who by his dominating position held back astronomical research in England for a generation, and of Sir Humphry Davy, who discouraged the work of Faraday, when the latter was his assistant.
Humphry Ward in her well-remembered "Robert Elsmere," and as she has again in the novel which happens to be her latest as these words are written, "Marriage a la Mode." The thesis has a way of sticking out obtrusively in such efforts. Many readers may not feel this in "Felix Holt," which, whatever its shortcomings, remains an extremely able and interesting novel, often underestimated.
From that time to this, whatever differences there may have been as to the practical conclusions drawn from them, there has been a substantial agreement as to the grounds of our political, our social, our intellectual, and religious life. Paley would have found no difficulty in understanding Tillotson. Newton and Sir Humphry Davy could have talked together without a sense of severance.
For my own part, I cannot undertake to say which principle operated with me most powerfully, whether the romantic associations which Campbell's muse must ever call up, or the more matter-of-fact, but hardly less animated description, which Sir Humphry gives of the capital sport which he had in a stream of the same name; but of this fact I am quite certain, that the hopes of discovering the river behind every eminence, or coming suddenly upon it as I emerged from each successive grove, served to render me, during this hour and a half's progress, proof against the encroachments of weariness.
Humphry Davy was faithful but showed no talent in school, having "the reputation of being an idle boy, with a gift for making verses, but with no aptitude for studies of a graver sort." Later in life he considered it fortunate that he was left so much to himself.
Direck found himself the interested auditor of a real English country-house week-end political conversation. This at any rate was like the England of which Mrs. Humphry Ward's novels had informed him, but yet not exactly like it. Perhaps that was due to the fact that for the most part these novels dealt with the England of the 'nineties, and things had lost a little in dignity since those days.
It is perfectly clear, however, that Stephenson had ascertained the fact that flame will not pass through tubes of a certain diameter—the principle on which the safety-lamp is constructed—before Sir Humphry Davy had formed any definite idea on the subject, or invented the model lamp afterwards exhibited by him before the Royal Society.
Sir Humphry Davy’s subsequent modification of the tube-lamp, by which, while diminishing the diameter, he in the same ratio shortened the tubes without danger, and in the form of wire-gauze enveloped the safety-lamp by a multiplicity of tubes, was a beautiful application of the true theory which he had formed upon the subject.
