Excerpt from The English Patents of Monopoly (Classic Reprint)
My study of this subject has been conducted under the guidance of Professor Edwin F. Gay of Harvard University, and I am in debted to him for sympathetic assistance from first to last. I do not dare to think what my results would have been without his stimulus and encouragement, without his hints as to sources of ih formation, and without his suggestions as to the broader historical relations of my subject. A service that I could ill have spared was his conscientiously thorough criticism of my work, for which I can not be too grateful.
