Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. Histology, or the minute anatomy of healthy tissue as revealed by the microscope, has made vast strides in' the last few years, and now forms a most important part of Medical education; a thorough knowledge of the normal structure of the animal tissues being absolutely necessary for the appreciation of pathological change. This subject is now taught at the Medical schools, and there is no excuse for a student who has finished his curriculum without some knowledge of practical histology, and of the minute anatomy of the human body. There are many, however, who qualified some years ago, when little attention Was paid to this subject, who have consequently no practical knowledge of the methods required to prepare any morbid growth they may meet with in their professional career, or how to set about a microscopical examination of the same.
