“ The virus exercises an injurious influence on the foetus, 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. ”

“ While the disease is incubating, there is nothing to show that infection has occurred.
_The Primary Lesion._--The incubation period having elapsed, there appears at the site of inoculation a circumscribed area of infiltration which represents the reaction of the tissues to the entrance of the virus. The first appearance is that of a sharply defined papule, rarely larger than a split pea. Its surface is at first smooth and shiny, but as necrosis of the tissue elements takes place in the centre, it becomes concave, and in many cases the epithelium is shed, and an ulcer is formed. ”

“ Syphilis is an infective disease due to the entrance into the body of a specific virus. It is nearly always communicated from one individual to another by contact infection, the discharge from a syphilitic lesion being the medium through which the virus is transmitted, and the seat of inoculation is almost invariably a surface covered by squamous epithelium. ”

“ Such an ulcer has an elevated border, sharply cut edges, an indurated base, and exudes a scanty serous discharge; its surface is at first occupied by yellow necrosed tissue, but in time this is replaced by smooth, pale-pink granulation tissue; finally, epithelium may spread over the surface, and the ulcer heals. As a rule, the patient suffers little discomfort, and may even be ignorant of the existence of the lesion, unless, as a result of exposure to mechanical or septic irritation, ulceration ensues, and the sore becomes painful and tender, and yields a purulent discharge. ”

“ There is abundant evidence that the Wassermann test is a reliable means of establishing a diagnosis of syphilis.
A definitely positive reaction can usually be obtained between the fifteenth and thirtieth day after the appearance of the primary lesion, and as time goes on it becomes more marked. During the secondary period the reaction is practically always positive. In the tertiary stage also it is positive except in so far as it is modified by the results of treatment. In para-syphilitic lesions such as general paralysis and tabes a positive reaction is almost always present. ”

“ In the male the possibility of infection taking place is increased if the virus is retained under cover of a long and tight prepuce, and if there are abrasions on the surface with which it comes in contact. The frequency with which infection takes place on the genitals during sexual intercourse warrants syphilis being considered a venereal disease, although there are other ways in which it may be contracted. ”

“ When the primary lesion has taken the form of an open ulcer with purulent discharge, or has sloughed, there is a permanent scar.
_Infection of the adjacent lymph glands_ is usually found to have taken place by the time the primary lesion has acquired its characteristic induration. Several of the glands along Poupart's ligament, on one or on both sides, become enlarged, rounded, and indurated; they are usually freely movable, and are rarely sensitive unless there is superadded septic infection. The term _bullet-bubo_ has been applied to them, and their presence is of great value in diagnosis. ”

“ In consequence of their divergence from the typical chancre, and of their being often met with in persons who, from age, surroundings, or moral character, are unlikely subjects of venereal disease, the true nature of erratic chancres is often overlooked until the persistence of the lesion, its want of resemblance to anything else, or the onset of constitutional symptoms, determines the diagnosis of syphilis. ”

“ The older the child, the less risk there is of its communicating the disease to others, until eventually the tendency dies out altogether, as it does in the tertiary period of acquired syphilis. It should be added, however, that the contagiousness of inherited syphilis is denied by some observers, who affirm that, when syphilitic infants prove infective, the disease has been really acquired at or soon after birth. ”

“ In the absence of mucous patches and ulcers, the sore throat may be characterised by a bluish tinge of the inflamed mucous membrane and a thin film of shed epithelium on the surface. Sometimes there is an elongated sinuous film which has been likened to the track of a snail. In the _larynx_ the presence of congestion, oedema, and mucous patches may be the cause of persistent hoarseness. The _tongue_ often presents a combination of lesions, including ulcers, patches where the papillae are absent, fissures, and raised white papules resembling warts, especially towards the centre of the dorsum. ”

“ Surgical interference may be required in the destructive gummatous lesions of the nose, throat, larynx, and bones, either with the object of arresting the spread of the disease, or of removing or alleviating the resulting deformities. In children suffering from keratitis, the eyes should be protected from the light by smoked or coloured glasses, and the pupils should be dilated with atropin from time to time, especially in cases complicated with iritis. ”

“ They are usually aggressive and persistent, with little tendency to natural cure, and they may be dangerous to life, because of the destructive changes produced in such organs as the brain or the larynx. They are remarkably amenable to treatment if instituted before the stage which is attended with destruction of tissue is reached. Early tertiary lesions may be infective, and the disease may be transmitted by the discharges from them; but the later the lesions the less is the risk of their containing an infective virus. ”

“ A solitary, indolent sore occurring on the lip, eyelid, finger, or nipple, which does not heal but tends to increase in size, and is associated with induration and enlargement of the adjacent glands, is most likely to be the primary lesion of syphilis. ”

“ Before the administration the patient must be overhauled; its administration is contra-indicated in the presence of disease of the heart and blood vessels, especially a combination of syphilitic aortitis and sclerosis of the coronary arteries, with degeneration of the heart muscle; in affections of the central nervous system, especially advanced paralysis, and in such disturbances of metabolism as are associated with diabetes and Bright's disease. Its use is not contra-indicated in any lesion of active syphilis. ”

“ The amount of mercury to be given in any case must be proportioned to the idiosyncrasies of the patient, and it is advisable, before commencing the treatment, to test his urine and record his body-weight. The small amount of mercury given at the outset is gradually increased. If the body-weight falls, or if the gums become sore and the breath foul, the mercury should be stopped for a time. ”

“ The edges are sharply cut, as if punched out; the margins are rounded in outline, firm, and congested; the base is occupied by gummatous tissue, or, if this has already separated and sloughed out, by unhealthy granulations and a thick purulent discharge. When the ulcer has healed it leaves a scar which is depressed, and if over a bone, is adherent to it. The features of the tertiary ulcer, however, are not always so characteristic as the above description would imply. It is to be diagnosed from the "leg ulcer," which occurs almost exclusively on the lower third of the leg ”

“ The gumma does harm by displacing and replacing the normal tissue elements of the part affected, and by involving these in the degenerative changes, of the nature of caseation and necrosis, which produce the destructive lesions of the skin, mucous membranes, and internal organs. ”

“ When syphilis occurs in a _pregnant woman_, she should be given in the early months an ordinary course of "914," followed by 10-grain doses of potassium iodide twice daily. The injections may be repeated two months later, and during the remainder of the pregnancy 2-grain mercury pills are given twice daily (A. Campbell) . The presence of albumen in the urine contra-indicates arsenical treatment.
It need scarcely be pointed out that the use of powerful drugs like "606" and "914" is not free from risk; it may be mentioned that each dose contains nearly three grains of arsenic. ”

“ 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_. ”

“ Such a patient is naturally anxious to know whether he has contracted syphilis or not, but neither a positive nor a negative answer can be given--unless the spirochaete can be identified.
Syphilis is also to be diagnosed from _epithelioma_, the common form of cancer of the penis. It is especially in elderly patients with a tight prepuce that the induration of syphilis is liable to be mistaken for that associated with epithelioma. In difficult cases the prepuce must be slit open. ”

“ It is the exception for a hard chancre to leave a visible scar, hence, in examining patients with a doubtful history of syphilis, little reliance can be placed on the presence or absence of a scar on the genitals. ”

“ It is to be borne in mind that in a certain proportion of men and in a larger proportion of women, the patient has no knowledge of having suffered from syphilis. Certain slight but important signs may give the clue in a number of cases, such as irregularity of the pupils or failure to react to light, abnormality of the reflexes, and the discovery of patches of leucoplakia on the tongue, cheek, or palate. ”

“ The patient complains of impairment of sight and of frontal or supraorbital pain. The eye waters and is hypersensitive, the iris is discoloured and reacts sluggishly to light, and there is a zone of ciliary congestion around the cornea. The appearance of minute white nodules or flakes of lymph at the margin of the pupil is especially characteristic of syphilitic iritis. ”

“ In isolated cases the temperature rises to 101 or 102 F. and the patient loses flesh. The lymph glands, particularly those along the posterior border of the sterno-mastoid, become enlarged and slightly tender. The hair comes out, eruptions appear on the skin and mucous membranes, and the patient may suffer from sore throat and affections of the eyes. ”

“ When protected from injury and irritation in the substance of an internal organ such as the liver, it may become encapsulated by fibrous tissue, and persist in this condition for an indefinite period, or it may be absorbed and leave in its place a fibrous cicatrix. ”

“ In _concealed chancres_ with phimosis, the sac of the prepuce should be slit up along the dorsum to admit of the ointment being applied. If phagedaena occurs, the prepuce must be slit open along the dorsum, or if sloughing, cut away, and the patient should have frequent sitz baths of weak sublimate lotion. When the chancre is within the meatus, iodoform bougies are inserted into the urethra, and the urine should be rendered bland by drinking large quantities of fluid. ”

“ 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--ozaena--the destruction of tissue may be considerable and result in unsightly deformity. ”

“ They appear as pustules, which are rapidly converted into small, acutely inflamed ulcers with sharply cut, irregular margins, which bleed easily and yield an abundant yellow purulent discharge. They are devoid of the induration of syphilis, are painful, and nearly always multiple, reproducing themselves in successive crops by auto-inoculation. Soft sores are often complicated by phimosis and balanitis, and they frequently lead to infection of the glands in the groin. ”

“ Sometimes the virulent character of the disease can only be accounted for by an idiosyncrasy of the patient. Constitutional symptoms, particularly pyrexia and anaemia, are most often met with in young women. Patients over forty years of age have greater difficulty in overcoming the infection than younger adults. ”

“ If the crust is detached, a sharply defined ulcer is exposed, and when this heals it leaves a scar which is usually circular, thin, white, shining like satin, and the surrounding skin is darkly pigmented ”

“ 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. ”
