PREFACE. vil
to Mr. Lawrence these acknowledgments are due. Associated with him for many years, I have largely participated in the benefit he has conferred upou all around him, by the example of his untiring zeal and fidelity of observation, and by the liberality with which he never fails to communicate know- ledge to all who are in search of it. I am also desirous of expressing to my able colleagues, Mr. Paget and Dr. Baly, my thanks for assistance in the preparation of this work.
Jt is necessary to observe, that notwithstanding the references, which will be found im the following pages, to another volume, containing “ Illustrations of the Effects of Disease and Injury of the Bones,” the two works are, in all other respects, wholly dis- tinct. The volume of IIlustrations contains, with the descriptions of the plates, full explanations of the subjects to which they relate, so that, in respect to these subjects, it is a complete and an independent work. �
