There are certain affections not at all uncommon and as a rule producing rather serious effects upon the social body, of which, though their existence is well known to all, very little is said. It is certain that what is considered the more severe of these venereal diseases may be acquired quite innocently. Indeed, many thousands of cases of this affection, acquired innocently, have now been reported by medical men in this country alone. If the statistics of all the world were gathered together, there would probably be a hundred thousand cases of this dreadful affection, which have been acquired without any blame on the part of the sufferer. It has become the custom, especially in English speaking countries, to ignore the presence of these diseases, and this has led to a multiplication of opportunities for their spread to such a degree that now the condition of affairs, for those who know it best, is rather alarming. It is with the intention that a few definite ideas, given absolutely without exaggeration and without any striving after effect, may enlist clergymen, as well as physicians, in a crusade against these diseases, that the present chapter is written.

It has been said over and over again at medical society meetings that it is a very unfortunate thing that universities in these modern times are situated in large cities. The young man just freed from the restraints of home life, or of the seclusion of a college, is at once without any preliminary training, exposed to all the dangers, moral and physical, of large city life. Not only is this true, but he is even not properly warned of the dangers that lie so close to his path. Our prudery has gone so far that the very names of these [{318}] affections are tabooed and above all must not be mentioned before the young. As to the awful evils that such diseases may cause, as to the lifelong suffering, even to mental degeneration and early death, that they may involve, not even a hint is considered to be proper. The consequence is that young men expose themselves not infrequently to danger, absolutely unknowing the significance that such diseases have in recent years acquired in the minds of modern physicians, and it is usually not until a serious mistake has been made that the young man is brought in contact with the physician who may be frank in pointing out evils utterly unknown before.

This state of affairs has come to be considered as so irrational in many foreign universities that now a special course of lectures is given every year on the significance of what may be called the social diseases. The students are told very frankly what the possibilities of danger for them in certain excesses may be, so that at least the young man can not say "I knew nothing about it," when the risk becomes an actual reality of danger. At the University of Berlin the first course of such lectures was established, and the interest aroused and the results obtained were such as to make other universities consider the advisability of such lectures for their students. Even here in prim and prude America, one or two of the great universities have come to the realisation that the physical well being of their students is committed to their care, as well as their intellectual development, and at least a beginning of that precious wisdom that comes from the fear of the physical evils of sin has been acquired because of opportunities provided by the faculty.

It is well admitted now by all that ignorance is not innocence and that knowledge of the consequences of social diseases is likely to be a very important factor in preventing young men from taking risks that would otherwise be considered very slight, perhaps. As a matter of fact, nothing can be more helpful from the ethical standpoint than this knowledge of how closely may follow the wages of sin, which is death. It is for this reason that clergymen would seem to owe it, as a duty to themselves and their position in social [{319}] life, to acquire a certain knowledge of these affections. A very great change has come over the attitude of the medical profession towards the so-called venereal diseases in recent years. A quarter of a century ago they were considered to be not very serious after all, and indeed in some cases to be no more serious than a cold, a mere passing incident in life. Now it is well recognised that almost never do they leave their victim in the state of health in which he was before, and that unfortunately the deterioration of tissues which has taken place is likely to be enduring. Even many years afterwards there may be serious complications involving health or even life.

For instance, it is now very generally conceded that paresis, or what is sometimes called general paralysis of the insane,—a progressive mental and nervous disease, which invariably ends fatally in from three to seven years,—is always due to one of the so-called social or venereal diseases. How important this affection has become in modern life can be best appreciated from the fact that in Europe nearly one in four of those who die in the insane asylums are sufferers from paresis. In this country the disease is not so frequent, the proportion being less than one in five or even one in six. The disease is becoming more and more common, however, as large city life becomes more prominent, and as the possibility of infection with social diseases is more widespread.

Paresis is what is sometimes called softening of the brain, and it attacks by preference men under thirty-five. The first symptoms of it as a rule are not alarming. A young man's disposition changes, so that an individual heretofore rather stingy becomes extravagant, while occasionally a prodigal becomes very saving and considers that he has already a large sum of money to his credit. The most prominent feature of the early stage of the disease is the occurrence of delusions of grandeur, that is to say, the patients get the idea that they are important personages, or that they have fallen heirs to a large sum of money, or that they have been appointed to high salaried positions. As a consequence of these delusions, they may make expensive presents to their friends. Occasionally there are other changes in disposition. A young [{320}] man, for instance, who has been of genial character becomes morose and hard to live with. The opposite change to greater liveliness of disposition is not unknown, but is more infrequent. Sometimes there are marked excesses, high living, luxurious habits, and the like, before the existence of disease is recognised.

The mental stigmata of the disease at the beginning are not alarming at all. There are slight lapses of memory. A man who has hitherto been known as an accurate mathematician, makes frequent mistakes in adding or multiplying. The physical signs are even slighter. In using long words, syllables are omitted from them. A favourite method of testing the speech of a person suspected of beginning paresis is to ask for the pronunciation of a word like Constantinople. Usually a syllable will be elided, and the reply will be "Constanople," or something similar. There is a slight tremulousness of the hands and usually a rather easily marked tremor of the lips, especially when the tongue is protruded. Often in the very earliest stage of the disease, there are changes in the pupils. They may be unequal, or may fail entirely to react to light.

When these signs are positive, that is, when there is a change in disposition and then the physical stigmata that we have gone over appear, the diagnosis of the disease is almost certain. The physician is able to say, with considerable assurance, that the young, strong, healthy-looking patient, who has often had to be tempted to come to see the doctor by some specious reason, because he does not consider himself that he has anything wrong with him, will have to be confined in an asylum within a year, or at most, two, and will die in a state of dementia within five years. This, of course, is an awful picture. This is the course of the disease in nearly 20 per centum of the inmates of our asylums. Almost without exception there is a history of syphilis in these cases, and the medical world is now persuaded that this is the most important factor in the production of paresis.

Another nervous disease, corresponding in some of its features to paresis and indeed sometimes spoken of as a spinal form of paresis, is locomotor ataxia. This affection [{321}] begins usually with loss of sensation in the soles of the feet so that the patient thinks that he is walking on carpet all the time. Before this there may have been some disturbance of vision. The pupils may fail to react to light. Occasionally the first symptoms are motor, that is, the man notices that he is not able to walk as readily as before. He staggers easily. If he tries to turn round while walking he is apt to lose his balance. If he tries to walk in the dark, he is almost sure to have so great a sense of insecurity that he dare not go far from the wall. Occasionally the first sign is a sinking of the limbs on the way down stairs. In certain very sad cases, the first and only symptom is a failure of sight which goes on progressively, until the optic nerve is completely destroyed and sight forever rendered impossible.

All these symptoms are traceable directly to certain changes which have been noted in the spinal cord. These changes are due to disturbance of the blood and lymph supply of the nervous tissue. Once the changes have taken place, there is no hope of the patient ever recovering the normal use of his limbs. Not infrequently he becomes bedridden and can not walk at all because he is not able to steady himself. He may not suffer in his general health, however, to any serious extent, and may live on for twenty years, though usually his resistive vitality is lowered and he is carried off by some intercurrent disease.
