So ended prematurely the worship of the Dynamo Deity, perhaps the most short-lived of all religions. Yet withal it could at least boast a Martyrdom and a Human Sacrifice. IX. THE MOTH. Probably you have heard of Hapley--not W. T. Hapley, the son, but the celebrated Hapley, the Hapley of _Periplaneta Hapliia_, Hapley the entomologist. If so you know at least of the great feud between Hapley and Professor Pawkins, though certain of its consequences may be new to you. For those who have not, a word or two of explanation is necessary, which the idle reader may go over with a glancing eye, if his indolence so incline him. It is amazing how very widely diffused is the ignorance of such really important matters as this Hapley-Pawkins feud. Those epoch-making controversies, again, that have convulsed the Geological Society are, I verily believe, almost entirely unknown outside the fellowship of that body. I have heard men of fair general education even refer to the great scenes at these meetings as vestry-meeting squabbles. Yet the great hate of the English and Scotch geologists has lasted now half a century, and has "left deep and abundant marks upon the body of the science." And this Hapley-Pawkins business, though perhaps a more personal affair, stirred passions as profound, if not profounder. Your common man has no conception of the zeal that animates a scientific investigator, the fury of contradiction you can arouse in him. It is the _odium theologicum_ in a new form. There are men, for instance, who would gladly burn Professor Ray Lankester at Smithfield for his treatment of the Mollusca in the Encyclopaedia. That fantastic extension of the Cephalopods to cover the Pteropods ... But I wander from Hapley and Pawkins.
