OSCAR, C. DEWOLF, A. M., M. D., Prof. Hygiene, Chicago Medical College, Commissioner of Health. City of Chicago Department of Health,} CHICAGO, Dec. 24, 1884.} I have been wearing during the past cold the Jaros Hygienic underwear. I have never worn underclothing which gave me so much satisfaction. The garments are light, warm and delightfully soft, and if properly washed retain their fleecy wool surface. OSCAR C. DEWOLF, A.

Dear Sir:--The "Jaros Hygienic Wear" is unsurpassed in its purpose of retaining an equable temperature and moisture of the surface of the body, thus preventing an undue and sudden chilling, thereby inducing catarrhs of the mucus membranes, conditions so common in this latitude. Its economy and therapeutic value is apparent. Respectfully, MARY HARRIS THOMPSON, M. D. * * * * * ROBERT H. BABCOCK, M. D., No. 70 Monroe Street, Room 29. MR. JAROS. CHICAGO, Feb. 10, 1887. Dear Sir:--I am sincere in expressing a favorable opinion of the "Jaros Hygienic Wear" so far as my experience allows me to judge. The patients to whom I have recommended it are of delicate health, very susceptible to cold. They uniformly expressed themselves as pleased with the garments made for them by you, and as having suffered far less from the cold this winter than usual: a result which they attribute directly to the power of the underclothing to prevent sudden chilling of the body upon transition from a high to a low temperature. Personally, I have worn the underclothing all winter, and believe my unwonted freedom from attacks of bronchitis due to the efficient protection afforded by the underwear. Your cloth seems to me to be a better non-conductor than other woolen materials, and therefore particularly suitable to persons with heart or lung disease. I am, very truly yours, ROBERT H. BABCOCK, M. D. * * * * * PLYMMON S. HAYES, M. D., Prof. Gynæcology, Chicago Polyclinic. MR. J. JAROS. CHICAGO, Aug. 11, 1886. Dear Sir:--I have found all the indications of a truly Hygienic Wear in your underclothing, and certainly consider it the ideal wear for this climate. Yours truly, PLYMMON S. HAYES, M. D. * * * * * We further refer, with permission, as to the therapeutic and prophylactic value of the Jaros Hygienic Wear, to the following medical gentlemen: S. SMITH, M.
