A Monograph of the Trilobites of North America

by Jacob Green

Some geologists imagine that the order of creation is registered in the rocks which compose the external crust of the earth, and that they can there clearly read a progressive development of organic life; in other words, that a succession of more perfect animals may be traced in ascending from the lower strata to the upper or more recent formations..

Our Nuclear Future

by Edward Teller

This book has been written for the layman who has no knowledge about atoms, bombs and radioactivity. He knows that the world is made of atoms, that bombs might destroy it and that radioactivity could make it a place much less agreeable to live in. We should like to give some advice about the use of the book: Each chapter can be read by itself...

The Moon - A Popular Treatise

by Garrett Putman Serviss

The reader familiar with astronomical literature will doubtless remark a certain resemblance between the plan on which this book is written and that of Fontenelle’s “Conversations on the Plurality of Worlds,” a French classic of the eighteenth century. The author freely acknowledges that it was the recollection of the pleasure which the reading of ..

Conversations on the Plurality of Worlds

In former geological ages, it roamed the continental areas of every zone; was found in nearly every section of North America, from the shores of the Arctic Ocean to the Gulf of Mexico, ..

The Life of the Grasshopper

by Jean-Henri Fabre

Fame is built up mainly of legend; in the animal world, as in the world of men, the story takes precedence of history. Insects in particular, whether they attract our attention in this way or in that, have their fair share in a folk-lore which pays but little regard to truth.For instance, who does not know the Cicada, at least by name? Where, in th..

Butterflies and Moths, Shown to the Children

by Theodore Wood

In this little book I want to tell you something about the common butterflies and moths which you may find in almost all parts of the country. But, first of all, I think that perhaps I had better say something about what we generally call their “life-history.”Of course you know that butterflies and moths are not butterflies and moths to begin with...
