DOING A FAVOR. 



Mr. Business Alan, there are two 

 ways of conferring a favor, and if you 

 can grasp the right way and stick to it. 

 it will mean many hundreds of dollars 

 in your pocket during the course of your 

 business life. When you are asked to 

 do a favor, make your decision mental- 

 ly. If you have to give your answer on 

 the spot, you may have to do some quick 

 thinking, but take a few minutes and 

 make your decision mentally. If your 

 decision is no, say no, and let that end 

 it. But if your decision is yes, say it 

 with a smile. 



If vou have to make A. sacrifice, let it 

 yield you a return. Do it gracefully. 

 Do it with a smile. It seems a simple 

 lesson, yet some men never master it. 

 They go through life, granting as many 

 favors as other men, and always doing 

 it in a grudging way. This is a huge 

 mistake. 



We know of no better lesson for a 

 young business man to master than this : 

 If you have to do a favor, do it grace- 

 fullv, and with a smile. — National Dnig-

A COMPARISON OF VARIOUS 

 PRESERVATIVES OF URINE.* 



By William M. Dchn and 

 Frank A. Hartman. 



In certain studies on normal urines, 

 incurring the collection and keeping of 

 hundreds of liters, the necessity of us- 

 ing a non-volatile preservative com- 

 pelled us to test a number of reagents 

 to determine their preservative powder. 



The ideal preservative for urine re- 

 quires continuous conformity to the 

 specifications (i) of being neutral or 

 acidic and non-volatile, (2) of having 

 efficient antiseptic power, (3) of being 

 free from hydrolytic or other chemical 

 efi^ects on the organic components of 

 urine and (4) of avoiding interference 

 with reactions involved in the ordinary 

 analysis of the urine. 



Though no single preservative meets 

 all of these requirements, a few ap- 

 proximate the same. How^ever, it is 

 scarcely to be expected that a solution 

 so complex as urine, containing so 

 many organic and inorganic com- 

 pounds, held in acidic-basic, hydrolytic, 

 precipitative, and oxidative equilibria, 

 can be maintained indefinitely in 

 its original composition. It is rather 

 to be expected that one preservative 

 will be effective with certain compo- 

 nents of the mixture, while another 

 preservative must be used for others. 

 Hence a variety of preservatives must 

 be studied and their modifying in- 

 fluences must be noted. 



For our purpose sulfuric acid was 



finally adopted, but our studies led 



us so far afield that w^e determined to 



make a systematic survey of preserv-
