I have had much pleasure in editing the following Memoir of my friend Mr. Nasmyth. Some twenty years since (in April 1863), when I applied to him for information respecting his mechanical inventions, he replied: “My life presents no striking or remarkable incidents, and would, I fear, prove but a tame narrative. The sphere to which my endeavours have been confined has been of a comparatively quiet order; but, vanity apart, I hope I have been able to leave a few marks of my existence behind me in the shape of useful contrivances, which are in many ways helping on great works of industry.”

Mr. Nasmyth, nevertheless, kindly furnished me with information respecting himself, as well as his former master and instructor, Henry Maudsley of London, for the purpose of being inserted in Industrial Biography, or Ironworkers and Toolmakers, which was published at the end of 1863. He was of opinion that the outline of his life there presented was sufficiently descriptive of his career as a mechanic and inventor.

During the years that have elapsed since then, Mr. Nasmyth has been prevailed upon by some of his friends—more especially by Sir John Anderson, late of Woolwich Arsenal—to note down the reminiscences of his life, with an account of his inventions, and to publish them for the benefit of others. He has accordingly spent some of his well-earned leisure during the last two years in writing out his numerous recollections.
