In preparing this edition I have endeavoured tomeet the requirements of students, and of practitionerswho desire to keep up their histologicalwork. Those methods are selected which havebeen found to work well in practice, and it hasbeen thought better to describe a few in detailrather than give a short account of many similarmethods.
I have again to express my obligation to thevarious instrument makers for the illustrations ofmicrotomes, &c.; to Dr. Fearnley, of Bradford,for the description of his method for injectingblood vessels, and to Messrs. Macmillan and Co.for permission to copy figures 10 and 11.
