 So fearfuliy and wonderfully is the kuman body made that scientists are beginning Co realize that many of the inventions of the day are iHfr,nge- ments on natures patent office \ good deal of trouble and worry in ta' past could have been avoided hal in. ventors made a careful study of the devices employed il making these hu- man bodies of ours the useful thug they are. Tue principles of the block and pulley or the tackle could have been discovered ages before hal the files of natures patent office been ran sacked. for there are several complete pulleys in the body. notably the one which moves the eyeball inward to- ward the nose.
 Engineers made exhaustive tests and experiments before they discovered that .a hollow shaft or rod of iron or steel is about twice as strong as a solid one Yet nature had patented this device in, our bones since the birth of Adam and Eve, and every impor- tant bone is practically constructed on this principle The ball and socket of the hip bones were the forerunners of the modern ball bearings, and 1t was the first automatic oiling machine used fin the world The value of air pres sure and vacuum was unknown to man until the last century, but every one of us carried the secret in the air tight hip joint which nature had as signed to lessen the muscular effort to hold our legs upright in position.
 Engineers have made wonderful progress in developing compound sue tion and circular pumps, but all of the principles contained in them are found in the heart. and this little pumping machine is still without rival in the mechanical world.
 The principles of the safety valve for steam engines are not so new as they seem Our human bodies carry with them the first automatic safety valves ever designed. There are up- ward of 2,5OO,O0O of them. We call them by the common name of sweat glands. Each such little gland has a safety valve which lets off heat from the body when it gets beyond a safe temperature We cannot stand rise of more than s to 10 degrees of tenn perature and live. If therefore the 2.5OOOOO safety valves were closed for twenty-four hours. death would super vene.
 Adams apple was the first storage cistern ever built. and it works with automatic regularity through health and sickness. 1t is most important organ of the body. although for cen turies it was considered d superfuous attachment It regulates the flow Of blood between the heart and the brain When it ceases to operate, somebody dies of apOpleXy or a rush of blood to the brain When the heart sends up too much blood to the head, the Adam s apple steps in to check the flow and store it up for future emergencies. If the heart is temporarily weakened or put out of good running order. the blood stored in this cistern is given up and sent to the brain. The perfect working of this little device is appar- ent when we consider how compara- lively few die of rush of blood to the brain or from deficiency of supply.
 The eye has score of small inven- lions worthy of recording, the ear nearly as many more and the vital organs an equal number. There is the liver with its quarantine station. Let any poisons enter our systems with food and they are immediately held up at this quarantine station and destroy ed by a secret process. It is only when poisons enter in large quantities that the station cannot handle them.
 But the stomach co-Operates with the liver and intercepts some of the poi sons. There are small machines there which manufacture minute quantities of hydrochloric acid from the salts eaten. This acid is made in exact pro portion to the amount of food consum- ed and suffices to destroy the microbes which we swallow. But there is even a third quarantine station located In
