"The names of these interesting young denizens of two worlds are so well known that it is perhaps unnecessary caution or superfluous gallantry to conceal them; but I will err, if error it be, on the safe side, and call No. 1 Miss C. and No. 2 Miss S., premising only that each is decidedly attractive, with the unquestioned advantage of having seen only some sixteen or seventeen summers apiece. Miss C. has been 'out' some time; her familiar being 'Katie King;' while Miss S. has made her debut more recently, having for her attendant sprites one 'Florence Maple,' a young lady spirit who has given a wrong terrestrial address in Aberdeen, and Peter, a defunct market gardener, who sings through the young lady's organism in a clear baritone voice. It was to me personally a source of great satisfaction when I learnt that Miss C. had been taken in hand by a F.R.S.--whom I will call henceforth the Professor--and Miss S. by a Serjeant learned in the law. Now, if ever, I thought, we have a chance of hearing what science and evidential acumen have to say on the subject of 'Face Manifestations.' Each of these gentlemen, I ought to mention, had written voluminously on the subject of Spiritualism, and both seemed inclined to contest its claims in favour of some occult physical--or, as they named it, psychic--force. This would make their verdict the more valuable to outsiders, as it was clear they had not approached the subject with a foregone conclusion in its favour. True, the Spiritualists claimed both the Professor and the Serjeant persistently as their own; but Spiritualists have a way of thinking everybody 'converted' who simply sits still in a decorous manner, and keeps his eyes open without loudly proclaiming scepticism. "Personally I had been, up to the date of present occurrences, accustomed to summarize my convictions on the subject by the conveniently elastic formula that there might be 'something in it.' I still think so; but perhaps with a difference.
