The Chemistry of Food and Nutrition By A.W. Duncan, F.C.S.   We may define a food to be any substance which will repair the functional waste of the body, increase its growth, or maintain the heat, muscular, and nervous energy. In its most comprehensive sense, the oxygen of the air is a food; as although it is admitted by the lungs, it passes into the blood, and there re-acts upon the other food which... more...

LECTURE I TEXTILE FIBRES, PRINCIPALLY WOOL, FUR, AND HAIR Vegetable Fibres.—Textile fibres may be broadly distinguished as vegetable and animal fibres. It is absolutely necessary, in order to obtain a useful knowledge of the peculiarities and properties of animal fibres generally, or even specially, that we should be, at least to some extent, familiar with those of the vegetable fibres. I shall... more...

Preface The author has had in mind a two-fold purpose in the preparation of this book. First, it is hoped that it may serve as a text or reference book for collegiate students of plant science who are seeking a proper foundation upon which to build a scientific knowledge of how plants grow. The late Dr. Charles E. Bessey, to whom I owe the beginning of my interest in plant life, once said to me:... more...

CHAPTER I. INTRODUCTORY. What constitutes a precious stone is the question which, at the onset, rises in the mind, and this question, simple as it seems, is one by no means easy to answer, since what may be considered precious at one time, may cease to be so at another. There are, however, certain minerals which possess distinctive features in their qualities of hardness, colour, transparency,... more...

INTRODUCTION. It is risky to go home with some of the company from the Chequers, for good-fellowship is by no means fostered in the atmosphere of a public-house. The creatures who write about the cheerful glass, and the jovial evening, and the drink that mellows the heart, know nothing of the sad work that goes on in a boozing-place, while the persons who draw wild pictures of impossible horrors are... more...

PRELUDE Shea had just beaten me at chess, as usual, and, also as usual, I had gleaned what questionable satisfaction I might by twitting him with this indication of failing mentality by calling his attention to the nth time to that theory, propounded by certain scientists, which is based upon the assertion that phenomenal chess players are always found to be from the ranks of children under twelve,... more...

THE MISSING BANK MANAGER Every Monday morning, when the clock of the old parish church in Scarnham Market-Place struck eight, Wallington Neale asked himself why on earth he had chosen to be a bank clerk. On all the other mornings of the week this question never occurred to him: on Sunday he never allowed a thought of the bank to cross his mind: from Sunday to Saturday he was firmly settled in the usual... more...

A TALK IN THE CHICKENYARD. "Why is it, I would like to know," said young Scratchfoot, throwing the sand over himself, "that every one is talking and carrying on of a hot Summer day the very time you ought to go to sleep?" "Hush up, Scratchfoot," said Topknot, "we are having a very lively conversation. Uncle Red Nose Mike has just asked a riddle, which none of us can guess.... more...

PROLOGUE It sometimes happens that a man is confronted by a perplexing crisis, before which he is quite at a loss how to direct his course. His familiar rules and habits seem to fail him, and his perplexity approaches dismay. At such a time, if his previous life has been guided by purpose and consideration, he may perhaps help himself by looking attentively back at the steps by which he has hitherto... more...

THE CHIEF ENGINEER It was a dark night in July — very dark. There was no moon and clouds hid the stars. We were sitting by the camp fire. Bige had just kicked the burning logs together so that a shower of sparks shot straight up toward the tree-tops, indicating that there was no wind, when he said, "If you want to make that picture of deer this is just the kind of a night to go for it. You... more...
