But if the course of development is arrested, so that some of the tissues remain on a plane that was normal for their remote ancestors, those tissues are able to exercise this power with the same energy that those ancestors could, and, if the arrest takes place sufficiently early, can give off buds capable of independent growth in the same way that those ancestors did. The arrest of development furnishes the opportunity. AV hen once development has been arrested, all that is necessary is the presence of some stimulus, mechanical or chemical, to rouse the latent repro¬ ductive power into activity. Development, like growth, is the result of chemi¬ cal changes in the tissues, changes that are taking place at the present time added to the accumu¬ lated results of all those that have taken place in former generations. Anything that interferes either with the inheritance of the products of past chemical changes, or with the working of recent ones, interferes with development and may arrest it. The structure of the tumours that are due to the awakening of the reproductive power of the tissues depends upon that of the parent stem , their rate of growth upon the maturity of the parent cell at the moment it gave oil the tumoui
