I observe you have thought proper to insert the last number of the Philosophical Magazine your opinion that my attempts at the safety tubes and apertures were borrowed from what I have heard of Sir Humphrey Davy's researches. The principles upon which a safety lamp might be constructed I stated to several persons long before Sir Humphrey Davy came into this part of the country. The plan of such a lamp was seen by several and the lamp itself was in the hands of the manufacturers during the time he was here.

I am glad to learn that the Parliament Bill has been passed for the Darlington Railway. I am much obliged by the favourable sentiments you express towards me, and shall be happy if I can be of service in carrying into execution your plans.
This railway is the most absurd scheme that ever entered into the head of a man to conceive. Mr. Stephenson never had a plan — I do not believe he is capable of making one. He is either ignorant or something else which I will not mention. His is a mind perpetually fluctuating between opposite difficulties; he neither knows whether he is to make bridges over roads or rivers, or of one size or another; or to make embankments, or cuttings, or inclined planes, or in what way the thing is to be carried into effect. When you put a question to him upon a difficult point, he resorts to two or three hypothesis, and never comes to a decided conclusion. Is Mr. Stephenson to be the person upon whose faith this Committee is to pass this Bill involving property to the extent of £400,000/£500,000 when he is so ignorant of his profession as to propose to build a bridge not sufficient to carry off the flood water of the river or to permit any of the vessels to pass which of necessity must pass under it.

It will hereafter be scarcely believed that an invention so eminently scientific, and which could never have been derived but from the sterling treasury of science, should have been claimed on behalf of an engine-wright of Killingworth, of the name of Stephenson — a person not even possessing a knowledge of the elements of chemistry.

Left home in company with John Dixon to attend the internment of George Stephenson at Chesterfield. I fear he died an unbeliever. When I reflect on my first acquaintance with him and the resulting consequences my mind seems lost in doubt as to the beneficial results — that humanity has been benefited in the diminished use of horses and by the lessened cruelty to them, that much ease, safety, speed, and lessened expense in travelling is obtained, but as to the results and effects of all that railways had led my dear family into, being in any sense beneficial is uncertain.
George Stephenson told me as a young man that railways will supersede almost all other methods of conveyance in this country — when mail-coaches will go by railway, and railroads will become the great highway for the king and all his subjects. I know there are great and almost insurmountable difficulties to be encountered; but what I have said will come to pass as sure as you live.
