After working on fishes, batrachians, reptiles, birds, and mammals, in which the structural development of some animals—man, for example—was found to be retrogressive and the physiological development progressive, the lessons closed with the study of man's structure as compared with the anthropoid apes and the few remains of prehistoric man, and finally with a discussion of the works of paleolithic man.

The teachers who had attended this course throughout the five years and had passed satisfactory examinations have been presented with diplomas testifying to their proficiency.

PROPER OBJECTS OF THE AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE.

By EDWARD ORTON,

PROFESSOR OF GEOLOGY IN OHIO STATE UNIVERSITY; PRESIDENT-ELECT OF THE AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE.

The objects of the American Association for the Advancement of Science are clearly expressed in the opening paragraph of its constitution, which was adopted at its first meeting, held September 20, 1848, in Philadelphia. From that day to this the paragraph referred to has not been modified except by the replacement of three words, viz., "the United States" by a single and more comprehensive word—"America."

As here defined, the objects of the association are "to promote intercourse between those who are cultivating science in different parts of America, to give a stronger and more general impulse and a more systematic direction to scientific research in our country, and to procure for the labors of scientific men increased facilities and a wider usefulness."
