    CHAPTER I. INTRODUCTORY. Histology is the science that treats of tissues; their structure, their components, their development luul modi- fication, and their arrangement to form the organs of the body. We may distinguish between Animal and Vege- table and between Normal and Pathological Histology, as well as between Human and Comparative Histology; expressions which define themselves. As the term Histol- ogy is most commonly used in medical literature it signi- fies the normal histology of man. In its most limited sense the term Histology is applied to the description of the tissues alone. This description is also sometimes called General Histology. The discussion of the arrangement of the tissues to form the organs of the body is distinguished as Histological Anatomy; or, (less appropriately) Physiological Anatomy. A Tissue may be defined as a mass of similar structural elements (cells or cell-derivatives) having similar prop- erties and functions; together with such substances as are characteristicalh'^ present between the elements (and are, as a rule, formed by their action), serving to unite them together.
