 question. 



Further study also reveals the fact that the 

 formida for Old Style dates requires modi- 

 fication for dates in January and February 

 of centennial years. This modification may 

 best be made by starring the figure 5 of the 

 formula and inserting the following footnote: 

 *Use 4 instead of 5 for dates in January and 

 Februarj' in centennial years.

THE LIBRARY OF THE LATE PROFESSOR 

 ZUNTZ 



To THE Editor op Science : A letter received 

 from a friend in Berlin a few days ago brings 

 information of the death of Professor N. 

 Zuntz. The very great services of Professor 

 Zuntz, extending over a long life time, 

 devoted to the advancement of physiology and 

 nutrition, his broad-mindedness and kindly 

 character render his death at this time, when 

 renewal of scientific associations severed by 

 the war is so important, peculiarly sad. 



The information comes also that, for the 

 support of his widow who is a hopeless invalid, 

 funds are needed. To this end it is desired 

 to sell the large library which Professor Zuntz 

 had collected. It includes complete sets of 

 practically all of the journals in his field of 

 work. By disposing of the library direct to 

 some purchaser, or purchasers, in this country 

 the advantage of the rate of exchange would 

 accrue to the widow instead of to some book 

 dealer. 



I shall be glad to supply the address and 

 such further information as 1 have to any 

 one interested in the purchase of this library.

QUOTATIONS 



WORK OF THE MAYO BROTHERS 

 A FRIEND of Christian civilization and a 

 supporter of the present social order rejoices 

 to visit such a shrine of philanthropy as can 

 be found at Rochester, Minnesota. To that 

 obscure and remote town came from England 



a good many years ago a physician and sur- 

 geon named Dr. W. W. Mayo. He had been 

 brought up in an atmosphere of scientific 

 progress and had studied with the English 

 physicist, Dalton. He settled down to a 

 general practise in Rochester and attained 

 eminence in his profession. He had two 

 sons, William and Charles, who followed his 

 profession and develoi)ed the highest known 

 skill in surgery, acquiring a reputation that 

 brought people from the country around to 

 seek relief at their hands. They soon dis- 

 covered that their income was quite beyond 

 their own need, and they conceived in their 

 breadth of vision the opportunity of philan- 

 thropic progressive work for relief of their 

 stricken fellowmen. They turned half of 

 their income over to a business friend, with 

 the request that he invest it and increase it; 

 and thus in the days of rapid increase in 

 values this fund became $2,000,000. Mean- 

 time their reputation grew, the demand for 

 their service and for the enlargement and 

 development of their plant greatly widened. 

 They adopted the principle that no one need- 

 ing surgical aid and coming to Rochester 

 should be turned away without receiving it; 

 that the rich and the moderately circum- 

 stanced should me made to pay in proportion 

 to their means, and that the man without any- 

 thing should receive aid for nothing. The 

 amount received from the wealthy they ap- 

 portioned with a view of creating a founda- 

 tion for their clinic, which should continually 

 enlarge its usefulness. Rochester is now a 

 town of 14,000. It now has constantly 4,000 

 to 6,000 transient residents who are there for 

 treatment. There are 900 beds all told in the 

 various hospitals, and something more than 

 300 are being added. Sixty-thousand cases of 

 all kinds are received and treated a year. 

 The iron rule is that the poorest shall receive 

 as careful and as good treatment as the 

 wealthiest. The result has been that the 

 name of the Mayos and Rochester has spread 

 to the uttermost quarters of the world, and 

 to-day a most cosmopolitan group greets the 

 visitor in all the buildings in which this great 

 philanthropy is carried on. As one notes the
