TRANSLATOR'S PREFACE. 



IT is hoped that the following translation of a few 

 of Dr. Pauli's papers may render some of the work of 

 this modest Viennese investigator already familiar to 

 a large circle of American and English workers accessi- 

 ble to yet others. The fundamental character of the 

 subjects touched upon by the author needs no com- 

 ment. It is only hoped that the translation may not 

 have lost too much of the spirit and the letter of the 

 original German. The volume as a whole represents 

 another stone in the structure of physical chemistry 

 in the biological sciences; and while it is not the 

 tendency of modern times to divide existing sciences 

 or to create new ones, specialism is followed as a 

 matter of necessity, so that it will not seem strange if 

 in the near future we shall come to recognize as branches 

 developing separately from the trunk which all these 

 sciences have in common, a physico-chemical physiology 

 and a physico-chemical pathology.
