IN DAILY LIFE BY MRS. PERCY FRANKLAND FELLOW OF THE ROYAL MICROSCOPICAL SOCIETY; HONORARY MEMBER OF JOINT AUTHOR OF "MICRO-ORGANISMS IN WATER," "THE life of pasteur," ETC. "Spirits, when they please, Can either sex assume, or both; so soft Nor founded on the brittle strength of bones, Like cumbrous flesh; but, in what shape they choose, Can execute their aery purposes, And works of love or enmity fulfil." MILTON. LONGMANS, GREEN, AND CO. 39 PATERNOSTER ROW, LONDON 1903 All rights reserved PREFACE THE title of this little volume sufficiently explains its contents; it only remains to add that much of the text has already appeared from time to time in the form of popular articles in various magazines. It has, however, been carefully revised and considerably added to in parts where later researches have thrown further light upon the subject's dealt with. G. C.
