INTRODUCTION. Definition of Soap—Properties—Hydrolysis—Detergent Action. It has been said that the use of soap is a gauge of the civilisation of a nation, but though this may perhaps be in a great measure correct at the present day, the use of soap has not always been co-existent with civilisation, for according to Pliny (Nat. Hist., xxviii., 12, 51) soap was first introduced into Rome from... more...

The remarks which Emily had made regarding the share Laura Middleton had had in opening up her ideas on the subject of the mysteries in which she had now been fully initiated had not escaped my observation. It so happened that at that very time I was under an engagement to pay a visit to the Middletons, who were very distant relations of my mother. It of course occurred to me that it was possible I... more...

"Painter and son of nature," wrote Voltaire, at that time the arbitrator and the dispenser of fame in cultured Europe, to Carlo Goldoni, then a rising dramatist, "I would entitle your comedies, 'Italy liberated from the Goths.'" The sage of Ferney's quick critical faculty had once again hit its sure mark, for it is Goldoni's supreme merit, and one of his chief titles... more...

JEAN MUIR "Has she come?" "No, Mamma, not yet." "I wish it were well over. The thought of it worries and excites me. A cushion for my back, Bella." And poor, peevish Mrs. Coventry sank into an easy chair with a nervous sigh and the air of a martyr, while her pretty daughter hovered about her with affectionate solicitude. "Who are they talking of, Lucia?" asked the... more...

THE RENEWAL OF LIFE Every human being must sooner or later know the facts concerning the origin of his life on the earth. One of the most puzzling questions is how and when such information should be given to the young. There is nothing the parent more desires than that his child should have a high ideal in regard to the sex-life and that he should live in accordance with that ideal, yet nowhere is... more...

FOREWORD This book is a faithful record, so far as I can make it, of the most marvellous phenomena which have come under my observation during the last sixteen or seventeen years. I have used my notes (made immediately after the sittings) and also my reports to the American Psychical Society (of which I was at one time a director) as the basis of my story. For literary purposes I have substituted... more...

LIGHT ON THE PATH I These rules are written for all disciples:Attend you to them. Before the eyes can see, they must be incapable of tears. Before the ear can hear, it must have lost its sensitiveness. Before the voice can speak in the presence of the Masters it must have lost the power to wound. Before the soul can stand in the presence of the Masters its feet must be washed in the blood of the heart.... more...

I THREE PERIODS OF PROGRESS The story of Robinson Crusoe is an allegory of human history. Man is a castaway upon a desert planet, isolated from other inhabited worlds—if there be any such—by millions of miles of untraversable space. He is absolutely dependent upon his own exertions, for this world of his, as Wells says, has no imports except meteorites and no exports of any kind. Man has no wrecked... more...
