When the fontanelle is deeply sunken, it points to loss of blood or other nutritive juices, as in cholera, &c. A sharp, shrill cry, accompanied by an expression of fright or great anxiety, and occurring about an hour after the child has fallen asleep, is the only symptom of the “ALP”—night terrors, sudden awaking from bad dreams. Periodical crying, lasting from five to ten minutes, should always make us think of spasm of the bladder or PAINFUL URINATIONS. Violent crying at stool with fear of the act, and general avoidance of it, points to FISSURE OF THE ANUS, and is usually accompanied with constipation. A violent cry full of pain and almost continuous, with the throwing about of the head on the pillow and grasping it with the hands, means OTITIS or EARACHE. Weakness or immobility of the child, after a comparatively slight or short illness, points to SPINAL PARALYSIS. Delayed ossification of the cranial bones is an early sign of RICKETS, as is crying continued for weeks (increased on touch of the extremities), accompanied with fever and incessant sweating. Vomiting of all kinds of food continued for weeks in children of closed cranium but with large cranial measurements, when there is no fever, pain, idiopathic disease, or a cerebral tumor, indicates chronic HYDROCEPHALUS with an acute onset. Congestion of the cheeks in children, excepting in cases of cachexia and chronic disease, indicates an INFLAMMATION or a febrile condition. Congestion of the face, ears and forehead of short duration, strabismus with febrile reaction, oscillation of the iris, irregularity of the pupil with falling of the upper lids, indicates a brain affection. Enlargement of the spongy portions of the bones indicates RICKETS. A thick and purulent secretion between the eyelids may indicate great PROSTRATION of the general powers. Passive congestion of the conjunctival vessels indicates approaching DEATH. Long continued lividity, as well as lividity produced by excitement or exercise, the respirations continuing normal, are indices of FAULT IN THE FORMATION OF THE HEART, or great blood vessels. A temporary lividity indicates the existence of a grave acute disease, especially of the respiratory organs. Irregular muscular movements, which are partly under the control of the will, indicates the existence of CHOREA (St. Vitus dance). The contraction of the eyebrows, together with a turning of the head and eyes to avert the light, is a sign of cephalalgia (headache). When the child holds its hand upon its head, or strives to rest the head upon the bosom of the mother or nurse, it may be suffering from ear disease. When the fingers are carried to the mouth, and there is besides great agitation apparent, and when it turns its head from one side to another, there is probably some obstruction or some abnormal condition of the larynx. A feeble and plaintive cry indicates a trouble in the abdominal regions.
