“Yet I ought not to disparage him unduly, for he was the one specimen in my collection, up to that time, who presented the orthodox ’stigmata of degeneration.’  His hair was bushy, his face strikingly asymmetrical, and his ears were like a pair of Lombroso’s selected examples; outstanding, with enormous Darwinian tubercles and almost devoid of lobules.

“Still, whatever his points of interest, he was but a stray catch.  Chance had brought him as it might bring others of the same kind in the course of years.  But this would not answer my purpose.  Numbers were what I wanted and what I had arranged for; and it was with deep disappointment that I recognized that my plan had failed.  The supply of anthropological material had come to an end.  In a word, the criminal class had ‘smoked’ me.

“This was not mere surmise on my part.  I had direct and very quaint evidence of it soon after I had completed the preparation of Number Five.  I was returning home one evening and was approaching the vicinity of my house when I became aware of a small man of seedy aspect who appeared to be following me.  I slackened my pace somewhat to let him overtake or pass me, and when nearly opposite my side door (the museum entrance) he edged alongside and addressed me in a hoarse whisper.

“‘Guv’nor.’

“I halted and looked at him attentively; a proceeding that caused him evident discomfort.  ‘Did you speak to me?’ I asked.

“He edged up closer, but still did not meet my eye, and, looking first over one shoulder and then over the other, replied, ’Yus, I did, guv’nor.’

“‘What do you want?’ I demanded.

“He edged up yet closer and said in a hoarse undertone, ’I want to know what you’ve been and done with my cousin Bill.’

“‘Your cousin Bill,’ I repeated.  ‘Do I know him?’

“’I dunno whether you know ‘im,’ was the reply, ’but I see ’im go into your house and I never see ’im come out agin, and I want to know what you’ve been and done with ‘im.’

“Now here was an interesting circumstance.  I had already noted something familiar in the man’s face.  His question explained it.  Cousin Bill was clearly Number Five in the Anthropological Series.  In fact, the resemblance was quite remarkable.  The present example, like the late Bill, was an undergrown creature, and had the same curiously-twisted nose, the same asymmetrical face and similar ears—­large, flat ears that stood out from his head like the handles of an amphora, that had strongly marked Darwinian tubercles, unformed helices and undeveloped lobules.  Lombroso would have loved him.  He would have made a delightful photograph for purposes of illustration, and—­it suddenly occurred to me—­he would make a most interesting companion preparation to Number Five.

“‘Your Cousin Bill,’ I said, with this new idea in my mind.  ’Was he the son of your mother’s sister?’ (A few details as to heredity add materially to the value and instructiveness of a specimen.)
