Jordan & Burrows' Bacteriology

With The fact that the Thirteenth Edition of this text has gained 87 adoptions is

Nearly 200 alone conclusive evidence of its excellent adaptability to modern educationalIllustration needs. It is in all respects a well-rounded and thoroughly balanced text. Each

Illustrations type of bacteria is of course fully described, including methods of study, effects

of each type, mode of transmission, etc. Worthy of special note are such features as the extensivechapter on Bacterial Physiology; the full coverage of epidemiology; the two chapters on Immunity;the complete discussions of Virus Diseases; the excellent chapters on the Bacteriology of Water andMilk; etc., etc. By every measure of value, this book can be recommended.

THE ROLE OF SCIENCE INSTITUTIONSIN OUR CIVILIZATION'

By Dr. WILLIAM D. COOLIDGEVICE-PRESIDENT AND DIRECTOR OF RESEARCH, GENERAL ELECTRIC COMPANY, SCHENECTADY, N. Y.

Mr. President, Members of the Board of Directorsof Ursinus College, Members of the Faculty, Membersof the Student Body, Dr. Pfahler, Ladies and Gen-tlemen:WE are met here to-day to dedicate this new temple

of science-to dedicate it to the service of mankindand to give it a name-a name worthy of the inspiringtradition which shall with the years grow up around it.In our evaluation of the importance of this event

we are more in danger of under- than over-estimation.We can, of course, judge the future only by the past.So let us think of the consequences of similar occasionswhich have already taken place. To mention only a

few examples drawn from the field of physical andchemical science:Once upon a time there was doubtless a dedication

ceremony for the physics institute of the Universityof Wurzburg, and it was in that laboratory thatRoentgen later discovered the x-rays and publishedhis results in a series of papers which have had soprofound an influence on science and on our civiliza-tion. It is of course the man rather than the institu-tion to whom we give most of the credit. The factremains, however, that the institution attracted himand -he was, perhaps unconsciously, inspired by itstraditions.In the same way consider the importance of the

founding of the Royal Institution, where Faraday did
