IV.--It is better when the physician, upon the occasion of his first visit, finds the patient lying upon one side, with his hands, neck and thighs slightly flexed, and the entire body placed in a perfectly natural position, like that which a man assumes in bed when he is in a state of health. It is not so well when the physician finds the patient lying upon his back, with his hands, neck and thighs extended. But if the latter is found curled up and sliding down toward the foot of the bed, this is an unfavorable sign. Finally, if he is found with rather cold feet projecting from under the bedclothes, and with his arms outstretched and his neck and thighs exposed, his condition may be considered dangerous, for this attitude of the body betokens an agitated state of the mind. If the patient sleeps with his mouth constantly open, lying upon his back and with his thighs strongly flexed and widely separated, it may be assumed that death is near at hand. If he lies upon his belly when it is known that he was not in the habit of sleeping in this manner before he was taken ill, the inference is warranted either that he is delirious or that he is suffering from pain in the lower part of his abdomen. Finally, if the patient shows an inclination to maintain a sitting posture while the malady is still in an active stage, this feature must be looked upon as a grave symptom and especially so in inflammation of the lungs. XIV.--Pus that has a whitish color and a uniform consistency, that is smooth and free from clumps, and the odor of which is only slightly unpleasant, is the least harmful. On the other hand, a pus which possesses the opposite characteristics is very dangerous. XL.--Severe pain in the ear, if associated with a persistent fever is dangerous, for the patient may become delirious and die.
