It was not until the eighth day that the final rites were performed, the days immediately subsequent to death having their own special ceremonies. The Turks were also fearful of premature interment and subjected the defunct to every test; among others, one was to examine the contractility of the sphincter and, which shows their keen observation of a well-known modern medical fact.

It seems also established that it was he who first discovered the valves of the veins, that he made known the most beautiful function of the iris, its contractility, and that various surmises of his regarding heat, light, and sound have since been developed into scientific truths.

And not only was this gradually discovered, but it was found that these semifluid contents of the plant cell had, in many cases, a remarkable power of contractility quite like that of the substance of animals.

Among the lower plants, it is the rule rather than the exception, that contractility should be still more openly manifested at some periods of their existence.

Close observation of the newly-opened lobster would soon show that all its movements are due to the same cause the shortening and thickening of these fleshy fibres, which are technically called muscles. Here, then, is a capital fact. The movements of the lobster are due to muscular contractility. But why does a muscle contract at one time and not at another?

It diminishes or abolishes muscular contractility respectively when applied through the circulation or directly. It coagulates myosin and albumen. It causes insalivation by paralysis of the secretory fibers of the chorda tympani; increases the flow of bile; has no action upon the spleen.

The likeness is made stronger by his tufts of feathers, that correspond to the ears of the quadruped, by his large head, his round, full, and glaring eyes, set widely apart, by the extreme contractility of the pupil, and in his manners, by his lurking and stealthy habit of surprising his victims.

This is because of its resistance to any arrest of the circulation and also because its survival is easily shown by its contractility. By irrigation of the heart and especially of its coronary vessels the period of revival may be much prolonged.

And, so far as the conditions of the manifestation of the phænomena of contractility have yet been studied, they are the same for the plant as for the animal. Heat and electric shocks influence both, and in the same way, though it may be in different degrees.
