REPORT OF NATIONAL MUSEUM, 1923. 109 



Doctor Power also donated thirteen specimens of quinine sulphate 

 obtained over forty years ago from leading manufacturers all over 

 the world. These specimens have a particular historical significance 

 since they are portions of the original samples which were turned 

 over to an international committee of analysts to which was assigned 

 the task of formulating standard tests for the purity of this most 

 valuable medicine. 



Dr. C. H. Michel & Company, Cleveland, Ohio, contributed a set 

 of seven anatomical charts and a rack for hanging the same on the 

 wall. 



Due to the efforts of Dr. Marcus Benjamin of the U. S. National 

 Museum, this division received by donation from Mrs. John Van 

 Rensselaer Hoff, of Washington, D. C, a silver salver and an illumi- 

 nated testimonial letter presented to her husband, the late Colonel 

 John Van Rensselaer Hoff, by military surgeons of the United States. 

 During the American occupation of Porto Rico, the island popula- 

 tion was vaccinated and freed from smallpox under the supervision 

 of Colonel Hoff. The salver and testimonials show in what esteem 

 Colonel Hoff was held by his fellow surgeons in the United States 

 Army, not only because of his successful work in Porto Rico, but also 

 for the interest which he took in medicine and surgery in general. 



Dr. W. D. Bayley, 1712 Walnut Street, Philadelphia, Pa., pre- 

 sented two of the early type sphygmographs and a curiously made 

 trocar. The sphygmograph is a surgical instrument for registering 

 the movements, form, and force of the arterial pulse, and the trocar 

 is an instrument used for tapping or piercing a cavity wall. 



The estate of Dr. E. A. Mearns, through Dr. C. W. Richmond, 

 Washington, D. C, contributed a medicine case supplied by E. R. 

 Squibb & Sons, New York, N. Y., for use of the Smithsonian African 

 Expedition under the direction of Colonel Roosevelt in 1909-1910. 

 Dr. E. A. Mearns, U. S. A., was physician of the expedition and 

 used the medicine case in question at that time. 



Dr. John Uri Lloyd, Cincinnati, Ohio, continued his helpful co- 

 operation and contributed a copy of the History of Medicine by 

 Alexander Wilder, M. D. 



Miss Emma M. Long, of Athens, Ga., daughter of Dr. Crawford 

 W. Long, the first surgeon to use ether as an anaesthetic in a sugical 

 operation, contributed an oil painting of this famous American doc- 

 tor. The portrait is the work of Miss Long and is said to be an ex- 

 cellent likeness of her father. 



Mrs. George A. Still, Kirksville, Mo., presented through Dr. 

 Norman C. Glover, of Washington, D. C, a photograph of her de- 

 ceased husband. Dr. George A. Still, who was killed as a result of 

 an accident on November 23, 1922. Doctor Still was president of the 

 American School of Osteopathy, Kirksville, Mo., and chief surgeon
