Houston street. New York. I-february, 10. 1895. During the past' few weeks X have re- celved so many letters concermng the same subject that It was entirely be>’0¥1d "W power to answer all of them lndivldualw- In viéw~of this I hope_that I shall be ex7 cused for the delay, which I much regret, in acknowledging the receipt, and also for addresslng this general communication in answer to all inquiries. The many pressing demands which hftV¢! been made upon me in consedkxence of ex- aggeratcd statements ot the `_1ournuls'have pa|nfuIly'lmpreae=c<\ me with the fact that there are n. great many sufferers, and fur- thcrmore.that nothing kinds a more power- ful echo than u promise held out to Improve the condition or the unfortunate ones. The members of the medical fraternity are naturally more deeply Interested In the task ot relieving the sufferlns: from their pain, and, as might bc expected, a. great many communlaatlong have been addressed to me by physicians. To these chlctiy this bric! statement or the actual facts isf ad~ dressed. Some journals have confounded the phys- lologlcal effects of electrical oscillations with those ot *ncchanlcal vlbratlons, this being probably due to the circumstance that u. few years ago I brought to the attention of scientific meh some novel methods and apparatus for t\he production of electrical oscillations which, I learn. are now largely used in some modification or other in elec- tro~thcrapeut|c treatment and otherwise. To dlspel this erroneous Idea. I wish to state that the effects ot purely mechanical vibra- tions which I have more recently observed, have nothing to do with the former. Mechanical vibrations have often been en?- ployed locally with pronounced results ln the treatment ot diseases. but lt seems that the effects I refer to have either not been noted at all, or\lf so. only lri'n. small de- gree, evidently because ol the lnsumcloncy o!.the means w,hlch have eventually been employed in the tnvestlgatlons. Whlle experimenting with a novel con- trlvance. constwutinfg in Ita simplest form s. vibrating mechanical system, ln which from the nature of the construction the ap-. pllerh force ls alwayg ln resonance with the nnLurs.\ perlodf I frequently exposed my body to eoptlnucd mechanical vibrations. Aa the elastic force can be made as large as desired and the applied force need be very small, great weights, halt ai dozen persons, for Instance, may be vibrated with great 'rapidity by a. comparatively small apparatus. I observad that such intense mechanical vibrations produce remarkable physiolog- ical eftectl. They affect powerfully the con- dition of the stomach, undoubtedly promot- ing' the process ot digestion and relieving the feeling of distress, often experienced ln consequence of the imperfect function of February IG. 1896 the organs concerned in the process. They have a. strong lnf1uencc_upon the liver. causing it to discharge freely, similarly to an application of n. cathartic. They also seem to affect t1he glandular system, not- ably in the ilmbsl: also the kidneys and blad- der and more or la-ss lnnucnce the whole body. When applied tor a longer pcriod they produce u feeling of immense fatigue, so that u profound sleep is induced. The excessive turing of the body ls gener- ally nccompanlcrh by nervous relaxation, but there seems to be,.bes1des, n, speclhc action on the nerves. These observattons, though Incomplete, arg, In my own limited judgment, neverthe- 'ldss po ltlve and unmistakable, and in vtuw of this and ot the Importance of further ln- veatlgatlon of the subject by competent men I prepared about u year ago n. mgphlno with nultuble adjustments for vdrylng the frequency and amplitude of the vibrations, intending to give It to some medical faculty tor invgstlgutlom This machine, together with other apparatus, was unfortunately destroyed by tires a year ago, but will be reconstructed as noon as possible. In mxiklng the mhovc- ntutoments I wish to disconnect mys<~lK‘wlLh the extmordtnnry opinions expressed In some journals, which I have never authorized and which, though they may have been made with good intent. cannot (all to he hurtful by giving rise to visionary cxpnctaxlons. Yours very truly, `N. TESLA. .__...l._ __
