Excerpt from Metabolism and Practical Medicine, Vol. 1I. Walker Hall has undertaken the laborious task of editing this English edition of my work, published in London by Mr. William Heinemann, and in Chicago by Messrs. W. T. Keener and Co. No person better fitted for this difficult duty could have been found, as I knew when I commended him for the purpose to my publishers. I believe that my English-speaking colleagues will agree with me when I say that Professor Walker Hall has acquitted himself brilliantly, and I herewith convey to him my most heartfelt good wishes and thanks.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
