sation tube was then attached to the recordingcylin- 

 der of the phonograph; the other end was phiced 

 on that part of the chest which was to be explored; 

 then the phonograph was set in motion before plac- 

 ing the tube in contact with the chest. In order to 

 register or record upon the wax cylinder, that part of 

 the chest which was intended to be examined, it was 

 found necessary, either before, or directly after 

 examining any part, to register by its anatomical 

 name that part of the chest. This was done by 

 speaking into the phonograph, so as to be able, in 

 reproducing, to distinguish those physical sounds 

 found in one part, from the other. 



For example, if I intend to examine the supra- 

 clavicular region, I speak into the phonograph 

 while in motion, before placing the tube on the 

 chest, "Supra-clavicular region." By so doing, 

 these words were directly registered. I now place 

 the tube on that part of the chest, and examine 

 slowly and thoroughly. In this way I continue to 

 explore the entire heart and lungs. *It will be found 

 advantageous to allow the cylinder to make a num- 

 ber of revolutions before removing the tube to 

 another part, in order that more than one respira- 

 tory sound might be registered. 



This is also to be carried out on examining the 

 heart sounds. 



When I was finished with my examination, I 

 turned back the reproducer, so as to repeat that 

 which was registered during the examination. The 

 phonograph was now set in motion ; a direct at- 

 tached stethoscope was applied to my ears, from the 

 phonograph. All the sounds were heard, in their 

 varied pitch and tone, as they came along, with 

 perfect clearness. The words and sentences that I 

 had spoken into it, for the purpose of recording the 

 landmarks, were all reproduced. 



These experiences have taught me in how many 

 other ways and manners the phonograph may be 

 practically applied to aid us for all purposes. 



With some extra experimenting, I was able to 

 apply the use of the phonograph in such a manner 

 as to throw the physical sounds, which had been 

 previously registered upon one of these wax cylin- 

 ders, into the auditorium, and thereby teach directly 

 a larger class of students. It is a known fact that 

 one can learn the tune of a song quicker, when he 

 repeatedly hears it, than when he tries to remember 

 such tones and sounds as they are taught by means 

 of words, without the material and thought togethe^ 

 simultaneously. 



To carry out my purpose for this manner of teach, 

 ing and throwing out the sounds some distance, I 

 was obliged to make the iollowing additional trials, 

 which finally led to success : 



To adapt the phonograph for the above aim, the 

 sounds had to be magnified by means of the micro- 

 phonic stethoscope, thence transmitted to the pho- 

 nograph, and upon the cylinder a trumpet of tin 

 was then made use of, which acted as a resonator 

 for the purpose of throwing out the sounds in a still 

 more magnified state. The trial proved to me that, 

 with some extra attachments, it will be the instru- 

 ment for carrying out that purpose. 



It is further possible to construct a physical-sign 

 cabinet, which has all registered cylinders repre- 

 senting the different diseases of the lungs and heart. 

 When one wishes to study any of the normal or 

 abnormal sounds of the heart or lungs, he can pick 

 out of his cabinet that cylinder which has registered 

 upon it such physical sounds.— J. M. Bi.yer, M. D.,

OBITUARY. 



The medical profession, and the scientific world 

 at large, mourns the loss of the eminent and es- 

 teemed physiologist. Dr. John Call Dalton, who 



died at his residence in New York onjthe morning 

 of the 1 2th of February, at the age of 64. He had 

 been suffering for some time from kidney trouble, 

 and an operation, made necessary by the disorder, 

 was recently performed, but without the desired 

 result. Dr. Dalton was president of the New York 

 College of Physicians and Surgeons, a close student, 

 and an original and industrious writer, and was the 

 first professor in this country to teach physiology 

 with illustrations in vivisection. He was born at 

 Chelmsford, Mass., Feb. 2, 1825, and early in life 

 evinced a fondness for the study of medicine. He 

 was educated at Harvard University, graduating 

 from the College in 1844, and from the University 

 Medical School in 1847. ^^^ developed a strong 

 liking for literary work, coupled with a taste for 

 physiology, and in 1851 attained considerable celeb- 

 rity by an original essay, entitled, "Corpus Lu- 

 teum," which was written in competition for the 

 annual prize offered by the American Medical Asso- 

 ciation. The reputation acquired by this effort led 

 to his appointment as professor in the medical de- 

 partment of the University of Buffalo, which he 

 resigned in 1854, to accept a similar professorship in 

 the Vermont Medical College. In 1859 ^^ removed 

 to the Long Island College Hospital, and remained 

 there for two years, as professor of physiology. In 

 April, 1861, he went to Washington, as surgeon of 

 the 7th Regiment, and in August of the same year 

 was appointed brigade surgeon of volunteers, and 

 served until March, 1864, when he resigned. Dur- 

 ing the winter of '64-'65 he delivered a course of 

 lectures on physiology, as a substitute for Dr. 

 Alonzo Clarke, before the College of Physicians and 

 Surgeons, of New York, and in 1865 accepted the 

 chair of physiology in that College, which he held 

 until 1883, when he resigned it to accept the presi- 

 dency of the institution. 



Dr. Dalton was vice-president of the New York 

 Academy of Medicine, from 1874 to 1877, and was a 

 member of the National Academy of Sciences, the 

 New York State Medical Society, the American 

 Medical Association, the New York Society of Neu- 

 rology and Electrology, the County Medical Society, 

 the New York Pathological Society, and the Medi- 

 cal Journal Association of New York City. 



Dr. Dalton was the author of a large number of 

 works and magazine articles on physiology and 

 other medical subjects. Among the most impor- 

 tant may be mentioned: "A Treatise on Human 

 Physiology," " A Treatise on Physiology and Hy- 

 giene, for Schools, Families, and Colleges," "The 

 Experimental Method of Medicine," "Doctrines of 

 the Circulation," "Topographical Anatomy of the 

 Brain," "Physiology of the Cerebellum," "Anatomy 

 of the Placenta," "Intestinal Digestion," and "Em- 

 bryology." 



Dr. Dalton never married. His family home is 

 in this city (Boston), where his two brothers now 

 reside. The funeral services were conducted at the 

 St. Bartholemew's Church, of New York, Feb. 14th, 

 the students of the College of Physicians and bur- 

 geons attending in a body. The remains were in- 

 tered at Lowell, Mass. J. H. E. 



Russian Physicians. — Dr. C. Yaroshevski con- 

 tributes to the Russkaya Meditsina a long article on 

 the state of the medical profession in Russia. He 

 points out that there are only 18,000 doctors for a 

 population of 100,000,000, or one medical man to 

 every 6,500 persons. This number of doctors in 

 proportion to the population is very much less than 

 in other European countries, yet the destitution 

 aiinong members of the profession is alarming. Of 

 late there have been numbers of suicides of medical 

 men who were without the bare necessaries of life. 

 Tlie fees for medical attendance are very low.

There is no better preparation for obtaining the effects of the 

 remarkable alkaloids present in the coca-plant than Afetcal/^s 

 Coca Wine. It is of uniform and standard strength, and can 

 always be relied upon as fulfilling in every respect the claims 

 made in its favor. The firm of T. Metcalf & Co. is one of the 

 oldest and best known drug and chemical houses in this city, 

 and all their preparations have an enviable reputation for purity 

 and superior quality.

Indian Relics. — Students of archxology are found in every 

 town and village of our land, and every State has yielded up to 

 the relic hunter more or less specimens of the Jiandiwork of the 

 races now almost or altogether extinct. With the view of 

 uniting, for the purposes of correspondence and study, the dif- 

 ferent interested persons in all parts of tlie country, an organi- 

 zation was recently formed, to be known as the American 

 Archaeological Association, /'lain Talk, a bright monthly 

 paper, published at 5 Beekman street, New York City, has been 

 selected as official organ, and a sample copy will be sent free to

HontforiVs Acid Pho>ipkate acts as a tonic for the stomach 

 and nervous system. Its specific use is to relieve irritation of 

 the bladder, prostate, testes and urethra, and to improve the 

 nutrition of the nervous system. Its use is also indicated in all 

 pains and indammations. Wherever the nervous system is 

 necessitated to spend its force and energy, the true remedy ts 

 acid phosphate. The greater the wear and tear the more neces- 

 sary is it to supply nerve food. It is a remedy of the highest 

 value in dyspepsia, sick headache, mental and pliysical exhaus- 

 tion, nervousness, diminished vitality, neuralgia and debility in 

 nursing women. Physicians have used it with unqualified sat- 

 isfaction. The utmost reliance can be placed upon it, for it is 

 without an equal in the treatment of all nervous diseases. 



Dk. William A. Hammond, the world-famed specialist in 

 mind diseases, says ;

"I am familiar with various systems for improving the mem- 

 ory, including, among others, those of Feinaigle, Gouraud and 

 Dr. Pick, and I have recently bectnne acquainted with the sys- 

 tem in all its details and applications taught by Prof. Loisette. 

 I am therefore enabled to state that his is, in all its essential 

 features, entirely original ; that its principles and methods are 

 different from all others, and that it presents no material analo- 

 gies to that of any other system. 



"I consider Prof. I^oisette's system to be a new departure in 

 the education of the memory and attention, and of very great 

 value; that it being a systematic body of principles and meth- 

 ods, it should be studied as an entirety to be understood and 

 appreciated; that a correct view of it cannot be obtained by 

 examining isolated passages of it. Willi am' A. Hammond.
