Miss Ormerod preserved very few letters except those necessary for scientific or business purposes, and these she classified and fastened into books for convenience of reference. Nothing else, and especially nothing which if returned to the writer, would hereafter lead to unpleasantness, escaped ordeal of fire. After keeping letters on general subjects for a few days, she would tear them up. The result is that, of the mass of interesting contributions on many subjects, which poured in to the oracle, first of Isleworth and latterly of St. Albans, from all sorts and conditions of men and women, the few sample letters written by prominent public men and reproduced in these pages, are almost all that remain. To some of her relatives she wrote very amusing letters, but—no doubt inspired by the desire to avoid all possible danger of hurting the feelings of people referred to—she exacted the promise that they should not be preserved. ------------------------------------------------------------------------ KEY TO MEDALS PRESENTED TO MISS ORMEROD AND SHOWN ON PLATE xxii.

MISS ORMEROD’S MEDALS, RECEIVED BETWEEN 1870 AND 1900, AS RECOGNITION BY SCIENTIFIC BODIES OF HER SCIENTIFIC WORK. (_pp. 96, 304._) ] ------------------------------------------------------------------------ CHAPTER XIII LETTERS TO COLONEL COUSSMAKER AND MR. ROBERT SERVICE Surface Caterpillars—Leopard and Puss Moths—“Hill-Grubs” of the Antler Moth. The letters in this the first chapter of correspondence (dealing with a number of moths, the caterpillars of which are destructive to vegetation), were written while Miss Ormerod was resident at Isleworth, and after she had issued seven of her Annual Reports. Apart from the Entomology discussed, the letters show how ready she was to recognise and to commend the meritorious scientific work of others. _To Colonel Coussmaker, Westwood, near Guildford._ DUNSTER LODGE, SPRING GROVE, ISLEWORTH, _August 1, 1885_. DEAR SIR,—Perhaps the best way I can reply to your inquiry about the coloured sheets is to enclose the short description, on the wrapper of one of my reports.[45]
