Although at the time of which I speak I had become more a director than a designer, I was originally by profession a mechanical engineer; and in my student days I had had a scientific training, some remnants of which still fluttered in tatters in odd corners of my mind. I could check the newspaper accounts of new discoveries in chemistry and physics well enough to know when the reporters blundered grossly; geology I remembered vaguely, though I could barely have distinguished augite from muscovite under a microscope: but the biological group of subjects had never come within my ken. The medical side of science was a closed book as far as I was concerned. Yet, like many educated men of that time, I took a certain interest in scientific affairs. I read the accounts of the British Association in the newspapers year by year; I bought a copy of _Nature_ now and again when a new line of research caught my attention; and occasionally I glanced through some of these popular _réchauffés_ of various scientific topics by means of which people like myself were able to persuade themselves that they were keeping in touch with the advance of knowledge. It was this taste of mine which brought me into contact with Wotherspoon; for, beyond his interest in scientific affairs, he and I had little enough in common. It is over a quarter of a century since I saw him last, for he must have died in the first year of our troubles; but I can still recall him very clearly: a short, stout man--“pudgy” is perhaps the word which best describes him--with a drooping, untidy moustache half-covering but not concealing the slackness of his mouth; fair hair, generally brushed in a lank mass to one side of his forehead; and watery eyes which had a look in them as of one crushed beneath a weight of knowledge and responsibility. As a matter of fact, I doubt if his knowledge was sufficiently profound or extensive to crush any ordinary person; and as he had a private income and no dependants, I could not understand what responsibilities weighed upon him. He certainly held no official post in the scientific world which might have burdened him; for despite numerous applications on his part, none of the Universities had seen fit to utilise his services in even the meanest capacity.
