The "Jaros Hygienic Underwear" has proven a most efficient guard, raising the condition of the men, and bearing out fully the recommendations of Dr. Henrotin. My personal experience is corroborative of this. Proper underwear makes an overplus of outer clothing, which is debilitating for men in service, unnecessary. I take pleasure in giving my opinion, and the result of experience with our men, and do not doubt that the underwear, when applied, will assert its worth in all the claims that are made for it.

JAROS HYGIENIC UNDERWEAR CO., Chicago, Ill. Dear Sirs:--From experience of men now using your Wear, it is indeed satisfactory. The Wear is all that you claim for it, and cannot fail of further adoption. Very truly yours, FRANK R. TATE, Secretary. * * * * * ST. LOUIS POLICE DEPARTMENT. GEO. HOMAN, M. D., Prof. Hygiene.

Dear Sir:--I am enabled by personal experience to testify to the comfort derived from the use of your Wear during the cold weather, and that the anticipated objection occurring to me before trial, namely, that the unmixed wool in contact with the skin might prove uncomfortable, has not appeared. In softness and warmth I have never worn any fabric that equals it, while my original impression at first sight in regard to the scientific construction of the principals upon which it is based, has been strengthened by experience. Very truly yours, GEO. HOMAN, M. D. * * * * * DETROIT POLICE DEPARTMENT. Accepted by advice of Dr. Book, Surgeon of Police Department, to Police Commissioners, Dec. 29, 1886. JAMES E.

Dear Sir:--I take pleasure in stating that the members of this department who used your undergarments (ex. heavy fleece) during the past winter, are unanimous in expressions of approval and satisfaction. They proved to be fully as efficacious for comfort, and protection against cold and change of temperature, as was promised for them. I have no doubt that the use of these garments, which was limited (it being first season) during the past winter, will be greatly extended in this department in the future. Respectfully, JAMES E. PITTMAN. * * * * * The Detroit Departments are now generally using the Underwear. The satisfaction and benefits from continued use being more marked. * * * * * WASHINGTON, D. C., POLICE DEPARTMENT.
