The P.P. smiled slightly, cleared his throat and, waving me to the further end of the menagerie, proceeded to answer my question. "The common or Sicilian guinea-pig," he began, "the _Porculus Auriferus Excubitor_ of BUFFON, is still fairly common, though I may say that it is many a day since they could be purchased for a guinea. An allied species, the Chinese or edible guinea-pig, the Sing Fat Soo of the Cantonese restaurateur, is indeed quite plentiful, but for some reason or other has never found favour with the leading English fanciers. The fact is that since the War our customers have become more discerning, and the common guinea-pig, being no longer called for, is not bred and has therefore ceased to be available for scientific purposes. A few of the art shades, notably _tete-negre_ and _beige_ pigs, are still in request by the furriers; but the public demand is for something more select. "Now here"--and reaching into an adjoining cage the Pontifical Personage extracted between finger and thumb a pinch of twitching fluff--"is the most highly-prized of the race, the blue Himalayan pig. Only five specimens have so far reached this country. The first pair were presented to the Duchess of Snoblands by the Maharajah of Khidmutgar about three years ago, but the sow met with an unfortunate accident in her ladyship's absence, being dipped into a box of face-powder by a thoughtless maidservant. The third specimen, a fine boar, was brought from China as the mascot of H.M.S. _Colossus_, but just after reaching harbour was accidentally devoured by the ship's cat. The remaining two I have here. They are expensive, of course, a hundred-and-five guineas the pair, but quite unique. "Of greater zoological interest perhaps is this little fellow, _Porculus Auriferus Decaudatus_, an arboreal species from the Solomon Islands; or the striated guinea-pig of Central Nicaragua, which I am happily able to show you." He placed Nicaragua's most valuable product in my hand, and it promptly bit me. That I did not drop it into a cageful of terrier-pups was wholly due to the native vigour with which _Striatus_ hung on. "The price of that is forty-five guineas," continued the Pontifical Person smoothly, as he restored it to its cage. I shivered. "Now here," he went on, "is a pig of real historic interest. I have a fair number of them just in from my collectors in the Persian Gulf and can do them at eighteen pounds the pair." He motioned me towards a larger cage wherein a bevy of dun-coloured piglets were holding a soviet. "The Sumerian or Desert Pig," he explained, "of the _Oxyrhynchus Papyri_, erroneously identified by GRENFELL and HUNT with the Southern form of the Tree Hyrax." It was at this point that my intelligence forsook me. I had been getting on too well. It was the old story of over-confidence. "Honestly now, old chap," I said, "and strictly between ourselves, do you ever sell any of the little beasts?"
