Description
LAËNNEC (René-Théophile-Hyacinthe). Autograph letter signed to Similienne Arthur de La Gauthraye in Rennes. Paris, March 10, 1825. 3 pp. in-8, address on spine; small tear due to opening without damage to text; preserved in a cardboard portfolio with garnet-red chagrin spine and bands, with title page in the same leather on the first cover (modern portfolio). "Mademoiselle et chère cousine, j'ai reçu ces jours derniers votre lettre du premier de ce mois. The information you give me about your health only shows me that to judge it properly, I would need a detailed examination of the state of the organs of respiration and circulation. I would therefore ask you to call one of my former students, Mr [Adolphe] Toulmouche, who has been based in Rennes for five or six years, and who is the only doctor, to my knowledge at least, in this town who is in the habit of USING THE STETHOSCOPE (the name of the instrument used for this examination). Please forward this letter to him; I would especially like him to note 1° THE STATE OF THE FORCE OF IMPULSE [ION] AND THE SOUND OF THE HEARTBEAT ; 2° THE STATE OF RESPIRATORY NOISE in the various parts of the chest; 3° rhonchi or rales, if developed at any point by breathing or coughing; 4° the results of percussion, especially in the anterior-superior parts of the chest and under the clavicles. All this may not be very intelligible to you, but Mr. Toulmouche will recognize it very well. As soon as you've sent me his observations, I'll be happy to send you my opinion...". VERY RARE DOCUMENT EVOKING THE STETHOSCOPE, INVENTED BY LAËNNEC IN 1816. This invention represented the greatest advance in physical medical diagnosis, between the discoveries of thoracic percussion by Leopold von Auenbrugger (1754) and X-rays by Wilhelm Röntgen (1895). Laënnec reported on his invention in 1819 in a seminal work, De L'auscultation médiate ou Traité du diagnostic des maladies des poumons et du cœur, based primarily on this new means of exploration.
