Abstract

PROF. M. H. E. TSCHERNING, director of the ophthalmological laboratory of the Sorbonne, Paris, has accepted the invitation of the council of the Optical Society to deliver the first Thomas Young oration on Thursday, October 17, and has chosen for its title “The Development of the Science of Physiological Optics during the Nineteenth Century.” The oration has been established for the purpose of providing an annual lecture on some subject connected with physical, geometrical, or physiological optics, and thus to further the development of those branches of science with which the name of Thomas Young is intimately associated. The orator is elected annually by the council of the Optical Society from persons eminent in these branches of science or technology.
