Gentlemen:--After a trial during the past winter of the JAROS HYGIENIC WEAR I am fully satisfied of its merits in both protecting and properly airifying the body, and especially do I recommend it as being well calculated for persons predisposed to a rheumatic diathesis and a general weakened condition of the nervous system, thereby greatly preventing liability in contracting colds. I also recommend it as a good general underwear because of its absorbing powers. I am, respectfully yours, S. A. CONKLING, M. D. * * * * * GEO. K. FRANKS, M. D. BURTON, W. Va., Feb. 13, 1888. J. JAROS, Esq. I have been wearing this winter the fleece-lined underwear of your manufacture. As a protection in extreme cold weather, especially for physicians in the country who have often to get out of a warm bed and ride several miles in the coldest weather, it has no equal. I have tried silk, as also the best of ordinary flannels, but they fall far short of the Jaros Underwear. It has always been my misfortune. I was easily affected by cold, viz: easy to take cold. Since wearing the Jaros Hygienic Underwear I have not had a single cold. For the underwear I claim as much a specific in rheumatism as quinine in intermittent. Since wearing your goods I have never had a single attack, while before I have not passed a winter without experiencing several severe attacks in the last twenty years. Respectfully yours, GEORGE K. FRANKS. * * * * * U. S. NAVY.--PAY INSPECTOR DEPARTMENT, U. S. Naval Academy. ANNAPOLIS, MD., Feb. 23, 1889. Gentlemen:--I cannot refrain from expressing to you the great satisfaction and enjoyment I have received from the use of your Jaros Hygienic Underwear during the past winter. I have been almost free from rheumatic pains, from which I have heretofore suffered greatly, and also enjoyed an exception from severe colds, which is a very unusual luxury with me in the winter season; all of which I must attribute to the protection afforded by my Hygienics. I am also gratified to find that with the proper care in washing there is no perceptible shrinkage. In short, in every way, I find them the most desirable article I have ever seen for the object to be attained. I shall be so loth to part with them that I hope you will manufacture a lighter grade for summer wear. You are at liberty to make any use you may see fit of my testimony. Very truly yours, THOS. T. CASWELL, Pay Inspector U. S. Navy. * * * * * FROM RT. REV. BISHOP CHENEY. CHAS. EDW. CHENEY. Rector's Study, Christ Church, 2409 Michigan Avenue,} CHICAGO, Nov. 29, 1886.} J.
