With the author’s dedication to Dr. Gibert. Some scattered foxing, but a good and nicely bound copy. Scarce.A curious thesis on phosphorescence or light in insects by Raphael Dubois, who discovered and named luciferine and luciferase. A nice feature of this thesis is formed by the graphs of the light emitted during flight. The mounted portrait of Paul Bert (1833-1886), a photo from the 1860's or 70's, is somewhat of a mystery. This French physiologist, politician, and diplomat, was founder of modern aerospace medicine. He found that an animal illness at high altitudes caused mainly by the low oxygen content of the sparse atmosphere. Bert also made a study of "the bends", suffered by deep-sea divers coming up too quickly to the surface from the great pressures of the depths. Apparently Dubois admired Bert, who died earlier that year.‎
