Gentlemen:--I am not in the habit of giving testimonials, and as a rule am opposed to any thing of the kind, but after suffering from rheumatism and kindred diseases for several winters, I was persuaded by a friend to try Hygienic Underwear, and I am compelled to say that from the time I began using them last November until spring I did not have a touch nor a single chill during the entire winter, and I am confident that it was attributable to the use of your Underwear, and I have not hesitated to recommend them at every opportunity. Yours truly, J. F. MERRY, Gen'l Western Passenger Agent. * * * * * In a letter to a friend, Mr. Merry wrote at the time of receiving the Underwear as follows. MANCHESTER, IA., Dec. 1, 1886. Going home yesterday to dinner, I found awaiting me a suit of underwear, and I was not very long in putting myself inside of them, but with no idea that I could wear them, having tried almost everything that contained wool, but never having found a garment I could wear next to my skin containing a particle of wool. I have worn the suit for two days without an unpleasant sensation; on the contrary, they are delightful, and just what I needed. Please have the following order filled for me. Yours truly, J. F. MERRY. * * * * * GEO. P. CARPENTER, M.D. CEDAR RAPIDS, IA., May 20, 1890. I have examined the Jaros Hygienic Underwear, and consider it the most perfect protection from severe cold and changes in temperature that I ever saw. Especially will this underwear be useful for those afflicted with rheumatism, lung troubles, or a dry condition of the skin. If the actual use of these goods substantiates the theory I have formed, they will be a valuable aid in the treatment of diseases, as well as to the comfort of the wearers. Respectfully, GEO. P. CARPENTER, M.D. TO I. JAROS. * * * * * Among others we refer also to the following medical gentlemen regarding the Therapeutic and Prophylactic value:
