Signs in this region might refer to either of these, for the reason that, although a sufficient intake of air is one of the necessary conditions of proper oxygenation, a free and abundant circulation of the blood through the air-cells is equally essential. In fact, that common phenomenon known as "shortness of breath" is more frequently due to disturbances of the heart and circulation than it is to the lungs, especially in patients who are able to be up and about. If, in addition to the danger signal of the rise and fall of the nostrils with each breath, we have a pale, translucent skin, with a light, hectic flush showing just below the knife-like lower edge of the cheekbone, a widely open, shining eye, and a clustering abundance of hair of a glossiness bordering on dampness, red lips slightly parted, showing the teeth between, a painfully strong suspicion of consumption would arise unbidden. This pathetic type of face has that fatal gift which the French clinicians, with their usual happiness of phrase, term _La beaute du diable_. The eager eyes, dilated nostrils, parted lips, give that weird air of exaltation which, when it occurs, as it occasionally does in the dying, is interpreted as the result of glimpses into a spirit world. When to this is added the mild delirium of fever, when memories of happier days and of those who have passed before rise unbidden and babble themselves from the tongue, one can hardly wonder at this interpretation. The last group of lines to be noted is that about the eyes and forehead. These are less reliable than either of the other two, for the reason that they are so sympathetic as almost invariably to be present in addition, whenever the lower dial-plates of the face are disturbed. It is only when they appear alone that they are significant; then they may be interpreted as one of three things: first, and commonest, eye strain; second, disease in some part of the nervous system or muscular system, not connected with the organs of the chest or abdomen; and third, mental disturbances. This last relation, of course, makes them in many respects the least reliable of all the face indices, because--as is household knowledge--they indicate mental conditions and operations, as well as bodily. "The wrinkled brow of thought," the "deep lines of perplexity," etc., are in the vocabulary of the grammar grades. They are, however, a valuable check upon the other two groups. They are not apt to be present in consumption and in other forms of serious disease, attended by fever, on account of the curious effect produced by the toxins of the disease, which is often not only stimulating, but even of an exhilarating nature, or will produce a slight stupor or lethargy, such as is typical of typhoid.
