![CELLULAK PATHOLOGY. Since tlie period wlien the higher powers of the compound micro- scope hegan to be applied to the investigation of morbid processes and the determination of the structm-e of tumours and other new formations, pathologists have been familiar with the fact, that cells and nuclei, in various stages of development and modifications of shape, enter largely into the composition of the new products of disease. The recognition of this very important structural fact must be regarded as the starting-point of the doctrine of Cellular Pathology.^ But whilst all, I suppose, are prepared to grant the cellular nature of morbid gi-owths, and the influence exercised by nucle- ated cells in pathological processes, yet there has been much dif- ference of opinion respecting the source from whence these cells arise. To attempt to follow out on this occasion the mode of origin of all the structures, and to discuss all the changes which may take place in disease of the textures, would indeed occupy far more time than could reasonably be allotted to a single lecture; and our infor- mation on many points is, perhaps, not as yet sufiiciently definite to enable one to state with precision many of the events which do occur. But I have thought that it might not be uninteresting to many now present, and quite within the compass of the time placed at my disposal, to give a brief account of some of the many careful and beautiful observations which have within the last few years been recorded on the mode of origin of the corpuscles which occur in such quantities in the so-called inflammatory exudations, and of the formation of the corpuscles of pus, cancer, and tubercle. And, indeed, it is not inappropriate that we in this place should inquire into the progress which has of late been made in the develop- ment of our knowledge of this department of our subject; for it was in ] It was by Johannes Miillcr and his pupils Schwann and Henle, nearly thirty years ago, that this great step was made in pathology.
