ST. PAUL, Minn, Jan. 1, 1890. MR. I. JAROS. Dear Sir:--The Jaros Hygienic Underwear has been in use with us for last three seasons, and I can highly recommend it to all Fire Departments, as this underwear is considered by us as the best possible protection against cold and changeable temperatures, which are especially characteristic of this latitude, and its use has resulted in great protection of health and a corresponding increased efficiency, and I find them the most desirable article I have ever seen for the object to be attained. Very truly yours, JOHN JACKSON, Chief Engineer. * * * * * OMAHA, NEB., FIRE DEPARTMENT. Office of Chief Engineer Omaha Fire Department, } OMAHA, NEB., Feb. 21, 1887.} J. JAROS, Esq., Chicago, Ill. Dear Sir:--With regard to the "Jaros Hygienic Wear," extra heavy fleece, I can say they have given eminent satisfaction among the number of members of the Omaha Fire Department, who have found it very comfortable in the biting blasts of winter, while fighting fire in exposed streets. These impenetrable undergarments are just the necessity for men whose calling keep them out doors in winter and at nights, and they will certainly meet with approval by all who try them in rigorous weather, as they were unanimously commended by my brave fellows in this metropolis of the Upper Missouri. Yours respectfully, J. J. GALLIGAN, Chief Fire Dept. * * * * * The Underwear has been largely used in the following Fire Departments, and the reports received from the men are satisfactory.

TOWN LAKE, ILL. * * * * * POLICE DEPARTMENT REPORTS. CHICAGO POLICE DEPARTMENT. INSPECTOR OF POLICE, City of Chicago, CHICAGO, January, 1889. On the recommendation of Dr. Henrotin, Surgeon of Police and Fire Departments, to Chief and Inspector of the Chicago Police Department, the "Jaros Hygienic Underwear" was brought to the notice of the members of the force, and has been used for a number of years with greatest satisfaction. The consideration of personal Hygiene to raise the efficiency of policemen, is gaining more general attention by Heads of Departments, and my personal observation as Inspector of this force is corroborative of, the necessity of regarding the question of clothing for officers; especially during the inclement and cold seasons, from October 1st to April 1st, when disabilities arise from exposure, which result in pulmonary and kidney troubles and rheumatic affections.
