[2] One of the Murdocks built the cathedral at Glasgow, as well as others in Scotland. The famous school of masonry at Antwerp sent out a number of excellent architects during the 11th, 12th, and 13th centuries. One of these, on coming into Scotland, assumed the name of Murdo. He was a Frenchman, born in Paris, as we learn from the inscription left on Melrose Abbey, and he died while building that noble work: it is as follows:-- "John Murdo sumtyme cait was I And born in Peryse certainly, An' had in kepyng all mason wark Sanct Andrays, the Hye Kirk o' Glasgo, Melrose and Paisley, Jedybro and Galowy. Pray to God and Mary baith, and sweet Saint John, keep this Holy Kirk frae scaith." [3] The discovery of the Black Band Ironstone by David Mushet in 1801, and the invention of the Hot Blast by James Beaumont Neilson in 1828, will be found related in Industrial Biography, pp. 141-161. [4] Note to Lockhart's Life of Scott. [5] This was stated to the present writer some years ago by William Murdock's son; although there is no other record of the event. [6] See Lives of Engineers (Boulton and Watt), iv. pp. 182-4. Small edition, pp. 130-2. [7] Mr. Pearse's letter is dated 23rd April, 1867, but has not before been published. He adds that "others remembered Murdock, one who was an apprentice with him, and lived with him for some time--a Mr. Vivian, of the foundry at Luckingmill." [8] Murdock's house still stands in Cross Street, Redruth; those still live who saw the gas-pipes conveying gas from the retort in the little yard to near the ceiling of the room, just over the table; a hole for the pipe was made in the window frame. The old window is now replaced by a new frame."--Life of Richard Trevithick, i. 64. [9] Philosophical Transactions, 1808, pp. 124-132. [10] Winsor's family evidently believed in his great powers; for I am informed by Francis Galton, Esq., F.R.S., that there is a fantastical monument on the right-hand side of the central avenue of the Kensal Green Cemetery, about half way between the lodge and the church, which bears the following inscription:--"Tomb of Frederick Albert Winsor, son of the late Frederick Albert Winsor, originator of public Gas-lighting, buried in the Cemetery of Pere la Chaise, Paris. At evening time it shall be light."--Zachariah xiv. 7. "I am come a light into the world, that whoever believeth in Me shall not abide in darkness."--John xii. 46.
