It is related that a certain blind and deaf mute was able to recog- nize, by the sense of smell, any person with whom he had previously come into contact. Every part of an organism is subject to certain alter- ations, caused by mechanical or chemical action; it gradually ceases to work when the products of reaction are not eliminated, and the loss of material is not equaled by fresh nutritives. Accordingly, we may say that the natural condition of every organism depends upon digestion and assimilation. How these two functions work we do not intend to demonstrate, as it can easily be found in any treatise on Physiology; only this we may be permitted to say, that the materials
