There is another cause of the falling birthrate which I will only indicate. However necessary it may be to look facts in the face, there are facts so ugly that they do not bear even contemplation. One great cause of the fall in the birthrate is the social disease. One or two quotations must suffice.

'I hold,' says Dr. Ballantyne, 'that in a given family, if syphilis enters it, it is the most deadly thing for the future of that family.'

'Have you any idea about the proportion of antenatal deaths which are due to syphilis?' 'Of course, one's idea is,' answered Dr. Amand Routh, 'that it is an enormous proportion—perhaps one-fourth....'

'Dr. Willey was of opinion that probably 32.8 per cent. of the total still-births were due to syphilis.'

'I would hold the view that it is a considerable proportion,' says Dr. Ballantyne, 'founding upon Fournier's evidence in France, where he speaks broadly of families being swept out of existence before birth by syphilis.'

'We have been recently told that there are 500,000 fresh cases of syphilis yearly in this country and three times that number of cases of gonorrhea.'

It is the opinion of Sir William Osler that of all the killing diseases syphilis comes third or fourth.[[3]] 'While we have been unable,' says the Commission on the subject, 'to arrive at any positive figures, the evidence we have received leads us to the conclusion that the number of persons who have been infected with syphilis, acquired or congenital, cannot fall below 10 per cent. of the whole population in the large cities, and the percentage affected with gonorrhea must greatly exceed this proportion.' Regarding all that, one can only re-echo the words of Sir Thomas Barlow: 'I think it is terrible.'[[4]]

It is only when the after-effects of these diseases are considered that the full measure of the peril which they create is realised. They not only lead to an enormous loss of child life, but they also undermine the health of those on whom they have fastened their fangs, transmitting the misery even to the third generation. The evidence shows that more than half the cases of blindness among children are the result of these diseases in the parents. Out of 1100 children in the London County Council Blind Schools at least 55.6 per cent. were clearly attributable to this cause. In adult life this evil is responsible for diseases which often manifest themselves after many years, such as general paralysis, affections of the brain and spinal cord, and epilepsy. It is because the people have been left in ignorance as to the terrible consequences not only to themselves but to their children, that the welfare and happiness of life are thus sacrificed to sin.

'It is one of the few diseases which are hereditary,' writes Sir Malcolm Morris, 'and in the hereditary form its effects are even more disastrous than in the acquired variety.... Many of its innocent victims die in the first few months of life from meningitis, hydrocephalus, convulsions, and other affections; if they survive they are liable to recrudescences of the disease up to the twentieth year or even later. Growth is checked, vitality depressed, intelligence stunted; hideous deformities may be produced, sight and hearing may be destroyed, and the central nervous system may be involved, with results similar to those which supervene in adults. What a story of mutilation and massacre of the innocents!'[[5]]
