Arrival of Prof. Ostwald of Leipzig

Professor Wilhelm Ostwald of the University of Leipzig who, under an arrangement for an exchange of professors, agreed upon between Harvard University and the German Government, is scheduled to lecture here during the first half of the present academic year, arrived in Cambridge yesterday afternoon. While here Professor Ostwald will offer Philosophy 3a, a course on the philosophy of natural science and Chemistry 17, and Chemistry 18, courses on the general subject of catalysis. Philosophy 3a will begin tomorrow at 10 o'clock in Upper Dane, and the first lecture in Chemistry 18 will be given on Thursday at 11 o'clock in Boylston 9.

Professor Ostwald is regarded as one of the founders of the modern science of physical chemistry and he has achieved a position of the highest rank in the scientific world, not only as an investigator and thinker, but also as a reformer, organizer, and teacher in the field of natural science. With J. H. van't Hoff, who received the degree of LL.D., from Harvard in 1901, Ostwald founded in 1887 the Zeitschrift fur physikalische Chemie, and in 1901 the Annalen der Naturphilosophie. In 1904 he gave the Faraday Lecture before the Royal Society. He has been a prolific and indefatigable investigator and writer, and a list of his publications would occupy several closely printed pages. Although he achieved eminence first in the field of physical chemistry, Professor Ostwald has during the last four or five years diverted, or perhaps extended, his studies to the broad field of the philosophy of science, a subject to which one of his best-known works, as well as the Annalen above mentioned is devoted.
