He restricts to vege- tables the power of immediately converting common \i. e. inorganic] matter into their own kind; and from this he draws the inference that a vegetable seems an intermediate link between common and animal matter. In his lectures on the Principles of Surgery, he re- views the accord [existing] between the physiologi- cal endowments of vegetables and those of animals. He mentions that a self-moving power has been observed and is universally allowed in vegetables; and he adds that • this principle seems to be as much a property in vegetables as in animals. He illustrates internal mechanical work done within the vegetable tissues by reference to Hales's notable experiments on the rising of the sap in trees; and he contrasts the magnitude of the force employed in this movement with that exerted in the heart's](https://iiif.wellcomecollection.org/image/b21778760_0014.jp2/full/800%2C/0/default.jpg)
