INTRODUCTION The year 1914 has no precedent in Stock Exchange history. At the present time (1915), when the great events that have come to pass are still close to us, even their details are vivid in our minds and we need no one to rehearse them.

The new happenings of all the World crowd upon each other so fast in the financial... more...

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.

PREFACE The silk industry of America has of late years rapidly advanced to the front rank among the great textile industries of the world. It may indeed be proud of this position, to which that enterprising spirit and untiring energy peculiar to our nation, combined with our great technical and natural resources, has brought it. That we are, on the other hand, not yet at the height of perfection we are also compelled to acknowledge, but if we... more...

CHAPTER I OF SURNAMES IN GENERAL "The French and we termed them Surnames, not because they are the names of the Sire, or the father,but because they are super-added to Christian names."
