Mucous patches on the tongue, cheeks, tonsils, and pharynx are common, often extending to the larynx, increasing the hoarseness, and to the nasal cavities, aggravating the snuffles. Both of these occurrences, by interfering with the respiration of the child and rendering its nursing interrupted and insufficient, greatly add to the gravity of the case. Enlargement of the spleen (common), enlargement of the liver (less so), and iritis (rare), may be mentioned among the phenomena of this stage, often associated with the skin eruptions.

About the time of the subsidence of the rash there may be developed the specific inflammation at the junction of epiphyses and diaphyses which produces a swelling of the long bones near their ends. The child will be noticed to cry a little when, for example, the wrist or elbow on one side is washed, and not to use these joints as much as the corresponding ones on the other side. The parts are not hot, only slightly tender, and as yet there is but little swelling. Later, the droop and the disuse of the affected limb become more noticeable and simulate infantile paralysis. There is, however, no wasting, no alteration of reaction by faradism, no real loss of power, so that the term pseudo-paralysis is an appropriate one. In a week or two similar symptoms will occur in the bone on the opposite side, and finally the ends of all the long bones may be affected; ordinarily the elbows, wrists, knees, and shoulders are the joints involved. Suppuration is rare, disjunction of the epiphysis from the diaphysis common. Recovery is apt to take place spontaneously within a month. The associated changes are chiefly endosteal at the junction of the shaft with the epiphysis, but there is also a little periostitis or perichondritis, which is the principal cause of the external swelling. Moderate deformity may ensue.210

Similar changes occurring in the cranial bones give rise to what has been called the natiform skull. During the first year it is very common for syphilitic children to develop a number of lenticular swellings on the cranium, which appear symmetrically around the anterior fontanel, but at a little distance from it; i.e. one on each frontal and one on each parietal bone. These are said to be "bossed." They are at first circumscribed, and in a child nine or ten months old often measure three-quarters of an inch to an inch in diameter. They are at first circular, afterward more irregular, and finally tend to organize, becoming diffused and massive and causing a permanent thickening of the skull.

These symptoms which have been described are the prominent ones occurring during the first six or eight or twelve months of life. If they do not manifest themselves before the eighth month, it is highly probable, even in a case with a syphilitic parental history, that the child will either escape altogether or that the secondary stage has been very slight and altogether intra-uterine and unattended with noticeable phenomena. If during this first year the child's cachexia is marked, if there are any intercurrent diseases, if the symptoms show themselves early, if the nasal or laryngeal affection is severe, if the eruptions are markedly bullar or pustular or ulcerative, if the enlargement of the spleen is great or the osseous lesions precocious or grave, and if, especially, there is any intermingling of tertiary symptoms, gummata, nodes, etc.,—the prognosis will be unfavorable.

From adolescence on through adult life the diagnosis of inherited syphilis will depend on the following points: First, of course, the history of parental or of infantile syphilis, or of both. Then a group of physical and physiognomical peculiarities, which are not definitely characteristic, and are of little value when taken separately, but are of considerable importance when all or a majority are present in any given case. These are low stature or puny development proportionate to the severity of the intra-uterine and infantile symptoms; a pasty, leaden, or earthy complexion,211 a relic of previous syphilodermata, probably also a result of malnutrition; a prominent forehead, bulging in the middle line at and within the frontal eminence, and due either to thickening of the skull or to a previous arachnitis and hydrocephalus before the ossification of the fontanels; a flat, sunken bridge to the nose, due to the coryza of infancy extending to the periosteum of the delicate nasal bones, and either interfering with their nutrition or partially destroying them; dryness and thinness of the hair, with brittleness and splitting of the nails; synechiæ and dulness of the iris (rare); ulcerations of the hard palate;212 and periosteal thickenings or enlargements of the shafts of the long bones near the ends, or slight angular deformity, results of the osteo-chondritis of infancy.

211 Trousseau (Clinical Lectures, vol. ii. p. 588, Philada., 1873), after calling attention to this peculiar hue of the face, says: "It not unfrequently happens that the physician, taught by long familiarity with this appearance, will almost at once diagnose syphilis after having simply seen the child's face, although the peculiar hue can be but vaguely described in words. The visage presents a special shade of bistre; it looks as if it had been lightly smeared with coffee-grounds or a very dilute aqueous solution of soot. There is neither the pallor, the icteric hue, nor the straw-yellow tinge of skin seen in other cachectic affections; the tinge is not nearly so deep, but is almost like that of the countenance of a recently-delivered woman, and either does not extend at all, or only partially, to the rest of the body. I know no disease except syphilis in which a child's skin has this peculiar color; and consequently, when it is well marked, it has more diagnostic value than any other symptom."

212 Mr. Oakley Coles reports (Proc. of Path. Society of Great Britain, vol. vii. p. 5) several cases of inherited syphilis in which there was wide separation of the jaws in the median line. In one family one member had typical teeth and wide separation; three others had the same separation, but not the characteristic teeth. It was suggested that in such cases the teeth were in size far below the average, and that the condition was that often observed where the jaws are in development in excess of the teeth which they contain. I. E. Atkinson details some interesting cases of this lesion in late hereditary syphilis, and attributes to it considerable diagnostic importance (American Journal of the Medical Sciences, New Series, vol. lxxvii., Jan., 1879, p. 71).

A much more valuable group of symptoms, however, are the following, which are mentioned in the order of their importance, any one of the first three being almost or quite conclusive:

Dwarfed permanent median upper incisors, broader at the top than at the cutting edge, which is crescentically notched, separated by an undue interval and converging toward each other.
