It is therefore evident that in order to understand propagation and just what is implied in the act we must make a closer analysis of cell-division, which will be attempted in the next chapters in this book.

Aside from the complex secondary aid which sex has given to the process of propagation among the higher forms of life, the most important fact which has always led to the conclusion that the two must have an elementary relation is the fact of fertilization.

We might easily understand ho...

In addition to extended studies of orchestral scores themselves, the standard works of Berlioz, Gevaërt, Riemann, Parry, and others have, as a matter of course, been referred to.

The subject under discussion has already been admirably handled by Lavoix in his voluminous work entitled "Histoire de L'Instrumentation," but it was unquestionably done through French glasses, and the scores of not one German romanticist are submitted to careful analysis beyond those of Weber and Wagner. "Parsifal"...

In the following pages an attempt has been made to emphasize the value of Embryology and Comparative Anatomy in elucidating the difficult and often complicated morphological problems encountered in the study of human adult anatomy.

Moreover, in addition to the direct advance in the method and scope of anatomical teaching afforded by these aids, it is further hoped that the broader interpretation, both of structure and function, obtained by ontogenetic and phylogenetic comparison, will impar...

It is chiefly through the labors of Gibbs and Heaviside that an analysis has been perfected which not only does away with the unnecessary complexity and artificiality of other analyses but offers a strictly natural and therefore as direct and simple a substitute as possible, and, at the same time in no wise is at variance, but runs paralel to them.

THIS NEW, yet old method is VECTOR ANALYSIS; it COMBINES within itself most of the advantages of both Quaternions and of Cartesian Analysis.

The...

The powers of living matter are still more characteristic. It is continually wasting away by a kind of internal combustion, but continually repairs the waste by the processes of growth.

Moreover, this growth is of a characteristic kind, differing absolutely from the so-called growth of lifeless things. Crystals and other lifeless bodies grow, if at all, by accretion, or the addition of new particles to the outside. Living matter grows from within by intus-susception, or taking in new particle...

In the greatly awakened interest in the common-school subjects during recent years, geography has received a large share. The establishment of chairs of geography in some of our greatest universities, the giving of college courses in physiography, meteorology, and commerce, and the general extension of geography courses in normal schools, academies, and high schools, may be cited as evidence of this growing appreciation of the importance of the subject.

While physiographic processes and resul...

"BE not afraid of greatness,'' says Shakespeare.'' Some men are born great, some achieve greatness, and some have greatness thrust upon them. '' Which are you? I will tell you. You were born great; you can achieve greatness if you will; and if you go about it the right way, you will have greatness thrust upon you.

The mistake so many people make is to confuse greatness with riches. The great man can have all he wants, but he need not necessarily become rich. Carlyle was no more intended to be...

The Republic is a Socratic dialogue written by Plato around 380 BC concerning the definition of justice and the order and character of the just city-state and the just man. The dramatic date of the dialogue has been much debated and though it must take place some time during the Peloponnesian War, "there would be jarring anachronisms if any of the candidate specific dates between 432 and 404 were assigned".

In re-writing the Solid Geometry the authors have consistently carried out the distinctive features described in the preface of the Plane Geometry. Mention is here made only of certain matters which are particularly emphasized in the Solid Geometry.

Owing to the greater maturity of the pupils it has been possible to make the logical structure of the Solid Geometry more prominent than in the Plane Geometry. The axioms are stated and applied at the precise points where they are to be used. Theo...

The following book, embody the results of an earnest attempt to set forth the chief characteristics of those heterogeneous nationalities which, in process of time and by virtue of conquest, have fallen under the dominion of Islam. The work deals with the Ottoman and Christian subjects of the Sultan generally, but chiefly with the Turks of Constantinople.

In the preparation of this edition of his work the author has endeavoured to bring the contents up to the present date, without, however, en...
