The Hulin Diary Calendar. 



This unique memorandum calendar, manufactured by John S. 

 Hulin, stationer, this city, combines a diary and a calendar in one. 

 5t consists of a book of daily leaves, which are made of thin writ- 

 ing paper, so that ink may be used. The upper part of each leaf, 

 -and the whole of the underlying page, is left blank, thus furnishing 

 three times the writing space of the ordinary memorandum calen- 

 dar ; and on the lower part is the day of the week, the month, and 

 also the date, in plain letters and large figures, as may be seen in 

 the accompanying cut. The diary calendar is intended to obviate 

 the defects of the oidinary calendar pad, by which (as each page's 

 Tiotes are daily torn off and thrown away), if one wants to recall a 

 circumstance or engagement, look up an address, or verify a date, 

 he has no means of doing so. By the use of this book, however, 

 ■which (as each daily sheet is turned behind the others) preserves 

 these numerous memoranda, records of events are kept which 

 would otherwise have been thrown away, and which may prove of 

 ralue some day. A memorandum book for the whole year is thus 

 ■supplied in which the expired dates are preserved through the year, 

 ■or as long as may be desired. Each date shows the number of 

 <lays in each month, and (for the convenience of business-men in 



figuring interest) the day of the year, thus rendering it easy to cal- 

 culate the number of days from one date to any other of the cur- 



rent or approaching year. On the covers are calendars for the 

 present and coming years, together with a perpetual calendar.

A New Method of Treating Disease. 



HOSPITAL REMEDIES. 



What are they ? There is a new departure in 

 the treatment of disease. It consists in the 

 collection of the specifics used by noted special- 

 ists of Europe and America, and bringing them 

 within the reach of all. For instance, the treat- 

 ment pursued by special physicians who treat 

 indigestion, stomach and liver troubles only, 

 was obtained and prepared. The treatment of 

 other physicians celebrated for curing catarrh 

 was procured, and so on till these incomparable 

 cures now include disease of the lungs, kidneys, 

 female weakness, rheumatism and nervous de- 

 bility. 



This new method of " one remedy for one 

 disease" must appeal to the common sense of 

 all sufferers, many of whom have experienced 

 the ill effects, and thoroughly realize the ab- 

 surdity of the claims of Patent Medicines which 

 are guaranteed to cure every ill out of a single 

 bottle, and the use of which, as statistics prove, 

 has I uined more stomachs than alcohol. A cir- 

 cular describing these new remedies is sent free 

 on receipt of stamp to pay postage by Hospital 

 Remedy Company, Toronto, Canada, sole pro- 

 prietors.
