books, together with chemicals and such other things as I might need in my retirement. The land which I had inherited was a narrow strip, consisting mostly of sand, and extending for rather over two miles round the coast of Mansie Bay, in Caithness. Upon this strip there had been a rambling, grey-stone building--when erected or wherefore none could tell me--and this I had repaired, so that it made a dwelling quite good enough for one of my simple tastes. One room was my laboratory, another my sitting-room, and in a third, just under the sloping roof, I slung the hammock in which I always slept. There were three other rooms, but I left them vacant, except one which was given over to the old crone who kept house for me. Save the Youngs and the M'Leods, who were fisher-folk living round at the other side of Fergus Ness, there were no other people for many miles in each direction. In front of the house was the great bay, behind it were two long barren hills, capped by other loftier ones beyond. There was a glen between the hills, and when the wind was from the land it used to sweep down this with a melancholy sough and whisper among the branches of the fir-trees beneath my attic window. I dislike my fellow-mortals. Justice compels me to add that they appear for the most part to dislike me. I hate their little crawling ways, their conventionalities, their deceits, their narrow rights and wrongs. They take offence at my brusque outspokenness, my disregard for their social laws, my impatience of all constraint. Among my books and my drugs in my lonely den at Mansie I could let the great drove of the human race pass onwards with their politics and inventions and tittle-tattle, and I remained behind stagnant and happy. Not stagnant either, for I was working in my own little groove, and making progress. I have reason to believe that Dalton's atomic theory is founded upon error, and I know that mercury is not an element.
