on a larger scale; the progress is much more rapid, involving in the course of months an area which in the case of tuberculosis would require as many years; the scars are sounder and are less liable to break down again; and the disease rapidly yields to anti-syphilitic treatment.

Tertiary lesions of mucous membrane and of the submucous cellular tissue are met with chiefly in the tongue, nose, throat, larynx, and rectum. They originate as gummata or as gummatous infiltrations, which are liable to break down and lead to the formation of ulcers which may prove locally destructive, and, in such situations as the larynx, even dangerous to life. In the tongue the tertiary ulcer may prove the starting-point of cancer; and in the larynx or rectum the healing of the ulcer may lead to cicatricial stenosis.

Tertiary lesions of the bones and joints, of the muscles, and of the internal organs, will be described under these heads. The part played by syphilis in the production of disease of arteries and of aneurysm will be referred to along with diseases of blood vessels.

Treatment.—The most valuable drugs for the treatment of the manifestations of the tertiary period are the arsenical preparations and the iodides of sodium and potassium. On account of their depressing effects, the latter are frequently prescribed along with carbonate of ammonium. The dose is usually a matter of experiment in each individual case; 5 grains three times a day may suffice, or it may be necessary to increase each dose to 20 or 25 grains. The symptoms of iodism which may follow from the smaller doses usually disappear on giving a larger amount of the drug. It should be taken after meals, with abundant water or other fluid, especially if given in tablet form. It is advisable to continue the iodides for from one to three months after the lesions for which they are given have cleared up. If the potassium salt is not tolerated, it may be replaced by the ammonium or sodium iodide.

Local Treatment.—The absorption of a subcutaneous gumma is often hastened by the application of a fly-blister. When a gumma has broken on the surface and caused an ulcer, this is treated on general principles, with a preference, however, for applications containing mercury or iodine, or both. If a wet dressing is required to cleanse the ulcer, black wash may be used; if a powder to promote dryness, one containing iodoform; if an ointment is indicated, the choice lies between the red oxide of mercury or the dilute nitrate of mercury ointment, and one consisting of equal parts of lanolin and vaselin with 2 per cent. of iodine. Deep ulcers, and obstinate lesions of the bones, larynx, and other parts may be treated by excision or scraping with the sharp spoon.

Second Attacks of Syphilis.—Instances of re-infection of syphilis have been recorded with greater frequency since the more general introduction of arsenical treatment. A remarkable feature in such cases is the shortness of the interval between the original infection and the alleged re-infection; in a recent series of twenty-eight cases, this interval was less than a year. Another feature of interest is that when patients in the tertiary stage of syphilis are inoculated with the virus from lesions from these in the primary and secondary stage lesions of the tertiary type are produced.

Reference may be made to the relapsing false indurated chancre, described by Hutchinson and by Fournier, as it may be the source of difficulty in diagnosis. A patient who has had an infecting chancre one or more years before, may present a slightly raised induration on the penis at or close to the site of his original sore. This relapsed induration is often so like that of a primary chancre that it is impossible to distinguish between them, except by the history. If there has been a recent exposure to venereal infection, it is liable to be regarded as the primary lesion of a second attack of syphilis, but the further progress shows that neither bullet-buboes nor secondary manifestations develop. These facts, together with the disappearance of the induration under treatment, make it very likely that the lesion is really gummatous in character.

Inherited Syphilis

One of the most striking features of syphilis is that it may be transmitted from infected parents to their offspring, the children exhibiting the manifestations that characterise the acquired form of the disease.

The more recent the syphilis in the parent, the greater is the risk of the disease being communicated to the offspring; so that if either parent suffers from secondary syphilis the infection is almost inevitably transmitted.

While it is certain that either parent may be responsible for transmitting the disease to the next generation, the method of transmission is not known. In the case of a syphilitic mother it is most probable that the infection is conveyed to the fœtus by the placental circulation. In the case of a syphilitic father, it is commonly believed that the infection is conveyed to the ovum through the seminal fluid at the moment of conception. If a series of children, one after the other, suffer from inherited syphilis, it is almost invariably the case that the mother has been infected.

In contrast to the acquired form, inherited syphilis is remarkable for the absence of any primary stage, the infection being a general one from the outset. The spirochæte is demonstrated in incredible numbers in the liver, spleen, lung, and other organs, and in the nasal secretion, and, from any of these, successful inoculations in monkeys can readily be made. The manifestations differ in degree rather than in kind from those of the acquired disease; the difference is partly due to the fact that the virus is attacking developing instead of fully formed tissues.

The virus exercises an injurious influence on the fœtus, which in many cases dies during the early months of intra-uterine life, so that miscarriage results, and this may take place in repeated pregnancies, the date at which the miscarriage occurs becoming later as the virus in the mother becomes attenuated. Eventually a child is carried to full term, and it may be still-born, or, if born alive, may suffer from syphilitic manifestations. It is difficult to explain such vagaries of syphilitic inheritance as the infection of one twin and the escape of the other.

Clinical Features.—We are not here concerned with the severe forms of the disease which prove fatal, but with the milder forms in which the infant is apparently healthy when born, but after from two to six weeks begins to show evidence of the syphilitic taint.

The usual phenomena are that the child ceases to thrive, becomes thin and sallow, and suffers from eruptions on the skin and mucous membranes. There is frequently a condition known as snuffles, in which the nasal passages are obstructed by an accumulation of thin muco-purulent discharge which causes the breathing to be noisy. It usually begins within a month after birth and before the eruptions on the skin appear. When long continued it is liable to interfere with the development of the nasal bones, so that when the child grows up there results a condition known as the “saddle-nose” deformity (Figs. 43 and 44).

Affections of the Skin.—Although all types of skin affection are met with in the inherited disease, the most important is a papular eruption, the papules being of large size, with a smooth shining top and of a reddish-brown colour. It affects chiefly the buttocks and thighs, the genitals, and other parts which are constantly moist. It is necessary to distinguish this specific eruption from a form of eczema which occurs in these situations in non-syphilitic children, the points that characterise the syphilitic condition being the infiltration of the skin and the coppery colour of the eruption. At the anus the papules acquire the characters of condylomata, also at the angles of the mouth, where they often ulcerate and leave radiating scars.

Affections of the Mucous Membranes.—The inflammation of the nasal mucous membrane that causes snuffles has already been referred to. There may be mucous patches in the mouth, or a stomatitis which is of importance, because it results in interference with the development of the permanent teeth. The mucous membrane of the larynx may be the seat of mucous patches or of catarrh, and as a result the child's cry is hoarse.

Affections of the Bones.—Swellings at the ends of the long bones, due to inflammation at the epiphysial junctions, are most often observed at the upper end of the humerus and in the bones in the region of the elbow. Partial displacement and mobility at the ossifying junction may be observed. The infant cries when the part is touched; and as it does not move the limb voluntarily, the condition is spoken of as the pseudo-paralysis of syphilis. Recovery takes place under anti-syphilitic treatment and immobilisation of the limb.

Diffuse thickening of the shafts of the long bones, due to a deposit of new bone by the periosteum, is sometimes met with.

The conditions of the skull known as Parrot's nodes or bosses, and craniotabes, were formerly believed to be characteristic of inherited syphilis, but they are now known to occur, particularly in rickety children, from other causes. The bosses result from the heaping up of new spongy bone beneath the pericranium, and they may be grouped symmetrically around the anterior fontanelle, or may extend along either side of the sagittal suture, which appears as a deep groove—the “natiform skull.” The bosses disappear in time, but the skull may remain permanently altered in shape, the frontal and parietal eminences appearing unduly prominent. The term craniotabes is applied when the bone becomes thin and soft, reverting to its original membranous condition, so that the affected areas dimple under the finger like parchment or thin cardboard; its localisation in the posterior parts of the skull suggests that the disappearance of the osseous tissue is influenced by the pressure of the head on the pillow. Craniotabes is recovered from as the child improves in health.

Between the ages of three and six months, certain other phenomena may be met with, such as effusion into the joints, especially the knees; iritis, in one or in both eyes, and enlargement of the spleen and liver.

In the majority of cases the child recovers from these early manifestations, especially when efficiently treated, and may enjoy an indefinite period of good health. On the other hand, when it attains the age of from two to four years, it may begin to manifest lesions which correspond to those of the tertiary period of acquired syphilis.

Later Lesions.—In the skin and subcutaneous tissue, the later manifestations may take the form of localised gummata, which tend to break down and form ulcers, on the leg for example, or of a spreading gummatous infiltration which is also liable to ulcerate, leaving disfiguring scars, especially on the face. The palate and fauces may be destroyed by ulceration. In the nose, especially when the ulcerative process is associated with a putrid discharge—ozæna—the destruction of tissue may be considerable and result in unsightly deformity. The entire
