Assiduous in visiting the sick, he found the real happiness of his life (one might almost say its real business) in his scientific and literary recreations. The range and diversity of these may be gathered from a list of his published writings: 'The Efficacy of Digitalis Applied to Scrofula,' 'On the Carpenter Bee (Apis Centuncularis),' 'Domestic Usage and Economy in the Reign of Elizabeth,' 'A Reply to a Query on Singular Fishes,' 'The Fabulous Foundation of the Popedom' (abridged from Bernard), 'Migratory Birds of the West of England,' 'God's Arrow against Atheism and Irreligion,' 'A Dissertation on the Mermaid,' 'Observations on the Natural History of the Chameleon,' 'Ditto on the Jewish and Christian Sabbath Days,' 'Ditto on Cider-making and the Cultivation of Apple Trees,' 'Contributions to a Classification of British Crustacea,' 'On Man as the Image of the Deity,' '_Daulias Advena_; or, the Migrations of the Swallow Tribe.' We select these from the output of one decade only. A little later the activity grows less miscellaneous, and he is drifting upon his _magnum opus_, as the titles indicate, 'Some Particulars of Rare Fishes found in Cornwall,' 'An Account of a Fish nearly allied to Hemiranphus,' 'On the Occurrence of the Crustacean Scyllurus Arctus.' He would announce these strange visitors--_sepia biserialis_, for an instance--with no less eagerness than a journalist hails the advent of a foreign potentate. He had invented, as we have said, an apparatus on which he mounted them, with a jet of salt water that played over their scales and kept fresh, as he maintained, the delicate hues he copied from his water-colour box; with what success let anybody judge who has studied the four great volumes wherein these drawings survive, reproduced by lithography, and published by subscription. Immersed in these studies, Doctor Unonius found no leisure to think of matrimony; and his friends and neighbours often took occasion to deplore it, for he was an extremely personable man, fresh-coloured and hale, of clean and regular habits, and, moreover, kind-hearted to a fault. All Polpeor agreed that he needed a wife to look after him, to protect him from being robbed; and Polpeor (to do it justice) did not say this without knowledge. The good man could never be persuaded that Polpeor folk--_his_ folk--were capable of doing him a wrong; but certain it is that learnedly as he wrote 'On the Cultivation of Apple Trees,' the fruit of his carefully tended standards and espaliers seldom arrived at his own table. They burgeoned, they bloomed; the blossom 'pitched,' as we say in the West; the fruit swelled, ripened, and then--
