INTRODUCTION. The investigation, the results of which are reported in this bulletin, was undertaken for the purpose of securing information in regard to the composition of brewery products made in this country. The main object of this investigation was to find, if possible, a means of distinguishing beers and ales made entirely from malt from those made from malt together with other cereal products, such as rice, corn, and cerealin. It was... more...

HABITATIONS AFFECTED BY ENVIRONMENT. It is conceded that the peculiarities of a culture-status are due chiefly to the necessities encountered during its development. In this sense the Pueblo phase of life was, like the Egyptian, the product of a desert environment. Given that a tribe or stock of people is weak, they will be encroached upon by neighboring stronger tribes, and driven to new surroundings if not subdued. Such we may believe was the... more...

CHAPTER I. INTRODUCTION. I propose in this book to describe a few of the more important earthquakes that have occurred during the last half century. In judging of importance, the standard which I have adopted is not that of intensity only, but rather of the scientific value of the results that have been achieved by the study of the shocks. Even with this reservation, the number of earthquakes that might be included is considerable; and I have... more...

ADVERTISEMENT. The following observations were thrown together as the result of communications with several gentlemen locally acquainted with the Isthmus of Panama, and who expressed to the writer their astonishment, that amidst the numerous undertakings, of more or less utility, which science has realised in our time, one so important to the whole commercial world, so easy of accomplishment, and so certain to be productive of ample remuneration... more...

Part First. THE USE OF THE BLOWPIPE.   Perhaps during the last fifty years, no department of chemistry has been so enriched as that relating to analysis by means of the Blowpipe. Through the unwearied exertions of men of science, the use of this instrument has arrived to such a degree of perfection, that we have a right to term its use, "Analysis in the dry way," in contradistinction to analysis "in the wet way." The manipulations are so... more...

United States New York, with over 5,000,000 inhabitants, has no effective market system. The buildings are out of repair, there is little or no organization, and the superintendent has testified before the New York Food Investigation Commission (March 12, 1912) that on their administration last year there was a loss to the city treasury of $80,000. To that must be added due consideration of the inconvenience to the consumers, producers and... more...

CHAPTER I. INTRODUCTORY. Assaying has for its object the determination of the quantities of those constituents of a material which add to or detract from its value in the arts and manufactures. The methods of assaying are mainly those of analytical chemistry, and are limited by various practical considerations to the determination of the constituents of a small parcel, which is frequently only a few grains, and rarely more than a few ounces, in... more...

INTRODUCTION Because of the rapid increase in knowledge about precious stones on the part of the buying public, it has become necessary for the gem merchant and his clerks and salesmen to know at least as much about the subject of gemology as their better informed customers are likely to know. In many recent articles in trade papers, attention has been called to this need, and to the provision which Columbia University has made for a course in... more...

Preface It was a day in the spring of 1921. Dismal shadows, really Hechtian shadows, filled the editorial "coop" in The Chicago Daily News building. Outside the rain was slanting down in the way that Hecht's own rain always slants. In walked Hecht. He had been divorced from our staff for some weeks, and had married an overdressed, blatant creature called Publicity. Well, and how did he like Publicity? The answer was written in his sullen eyes;... more...

BUDDHA About five hundred years before the birth of Christ a mighty king reigned in India over the land of the Sakyas, from which the snowy tops of the Himalaya Mountains could be seen. His name was Suddhodana and he had two wives called Maya and Pajapati; but for a long time they bore him no children, and the King despaired of having an heir to his throne. Then Queen Maya bore a son and after he was born, the legends tell us, she had a dream in... more...
