A third vital property is sensibility, which, however, requires that the tissues shall be united so as to form a continuous line from the part manifestino; it to the brain. This property is enjoyed in very different degrees by the different tissues, and constitutes an important distinction between them, dependino- upon the presence and number of nerve-fibres mixed with the tissue. The tissues, the manner of whose formation, and properties we have just described, are variously combined to constitute the organs of the body, all of which differ in their structure and use, but are combined for a double purpose, viz.: 1. The preservation of the individual; and 2. The continuance of the species. To effect these objects the organs are arranged in groups, each of which has a definite purpose or function to fulfil. Each group of organs is called an apparatus. The general distribution of organs is shown in the followina: table: A. For the Preservation op the Individual. 1. Apparatus of Relanon. A ^ i!
