In the infant it is the last of these which very often calls attention to the illness from which it is suffering. Cries are the only language which a young baby has to express its distress; as smiles and laughter and merry antics tell without a word its gladness. The baby must be ill, is all that its cries tell one person; another, who has seen much of sick children, will gather from them more, and will be able to judge whether its suffering is in the head, or chest, or stomach. The cries of a baby with stomach-ache are long and loud and passionate; it sheds a profusion of tears; now stops for a moment, and then begins again, drawing up its legs to its stomach; and as the pain passes off, stretches them out again, and with many little sobs passes off into a quiet sleep. If it has inflammation of the chest it does not cry aloud, it sheds no tears, but every few minutes, especially after drawing a deeper breath than before, or after each short hacking cough, it gives a little cry, which it checks apparently before it is half finished; and this, either because it has no breath to waste in cries, or because the effort makes its breathing more painful. If disease is going on in the head, the child utters sharp piercing shrieks, and then between whiles a low moan or wail, or perhaps no sound at all, but lies quiet, apparently dozing, till pain wakes it up again. It is not, however, by the cry alone, or by any one sign of disease, that it is possible to judge either of its nature or of its degree, but the mention of this serves merely as an illustration, which anyone can understand, of the different meanings that even a baby's cry will convey to different persons.
