It is on his researches in ichthyology, his list (no short one) of discoveries, his patient classification of British Fishes, that his fame rests. 'Why "British"?' the reader may ask. 'Have fishes, then, our nationalities?' The doctor liked to think so. He was a lover of his country, and for three years, while Napoleon threatened us with invasion, he had served as a second-lieutenant in that famous company, the East and West Looe Volunteer Artillery, better known as the Looe Die-hards. Now, in times of peace, with Britain supreme upon the seas, he boldly claimed for her every fish found off these shores. A sturgeon, even, might not visit our coastal waters, however casual the occasion, without receiving the compliment of citizenship for himself and his tribe. Yet Doctor Unonius patiently tracked these creatures in their most distant migrations--'_motus et migrationes diligentissime indagavit_,' says the mural tablet beneath the window. The three lights of the window represent (1) Jonah vomited by the Whale, (2) the Miraculous Draught of Fishes, and (3) St Peter, John Dory and the stater. Polpeor, you must know, is a fishing-haven on the south coast of Cornwall, famous during the Napoleonic Wars for its privateering, and for its smuggling scarcely less notorious down to the middle of the last century. The doctor's parents, though of small estate, had earned by these and more legitimate arts enough money to set them dreaming of eminence for their only child, and sent him up to London to Guy's Hospital, where he studied surgery under the renowned Mr Astley Cooper. Having qualified himself in this and in medicine, he returned to his native home, which he never again left--save now and then for a holiday--until the day of his death.
