BOLIVAR

by Reg Bankart 5, Smith & Durrell, 1941, unpaged. $1.00.

THIS IS A PLEASING tale, for the very young, of Bolivar a monkey with a very long tail. In spite of this, which for a time gave Bolivar an inferiority complex, he ultimately achieved his ambition and became KING. How he attained this office, highly important in the animal kingdom, is the subject of Mr. Bankart's tale. The illustrations are by the author and are, perhaps more than usual, an integral part of the book.

A Definition of Invention by John E. R. Hayes '95 has been privately printed, apparently by the author. In the September issue of the Journal of the Patent Office Society there is a review of this book by the editor, from which the following excerpts are taken:

A monograph giving a philosophical definition of invention and illustrating each phrase thereof by reference to leading cases. The writer, an experienced patent attorney and member of the Boston bar, starts off by defining invention as "a mental concept of a new and useful result inclusive of the mode of its physical attainment: which concept arises from an idea, or ideas, that are the product of new and original thought, or discovery, in the art to which the mental concept pertains, and which add to the sum of knowledge in said art " Chapters are devoted to Mental Concept, New and Useful Result, Mode ofPhysical Attainment, etc. Numerous cases, especially in the Supreme Court, are quoted and cited appropriately, and on the whole the monograph is carefully and thoughtfully done. This little volume, attractively printed and bound, should be a welcome and useful addition to any patent lawyer's library."
