There are still other causes of divorce. Their importance is so great, and the subject so closely concerns every citizen, that I have no hesitation in being even more explicit. In many cases the charge of infidelity is rested upon the communication, or supposed communication of infectious disease from one of the parties to the other. Often the charge is true, often it is false, at least so far as the imputation of sinful conduct is concerned. I disbelieve the statement so often made, that either one or the other of the two forms of specific disease has been occasioned, in the adult, by other than by sexual contact. The allegations as to water closets, soiled linen, &c., it has irreverently been remarked, should be allowed weight only in the cases of clergymen, or others supposed by their position to be above the scandalous practices of the every day world. There is no doubt that to children such disease has been communicated by suckling an unclean wet nurse, or by her using to bathe it the foul rags with which she had cleansed her own sores. In the case of adults, however, there are certain mistakes that can be made, that indeed have been made, and have plunged families into the deepest distress, the suspected party being wholly innocent. One of these errors depends upon the fact that the primary lesion of the most dreadful disease of unchastity may escape even the most careful scrutiny, or from its insignificant appearance may be considered of trifling importance. The disease being inheritable, may yet not be evinced in husband or wife save as tainting their children, the unmistakable signs of such taint being familiar to every physician, and upon this discovery of infidelity, it may be attributed to the wrong party. Another source of error is, that the other result of unfaithfulness may be simulated by the effects of peculiar irritations, or of the chastest congress under certain circumstances. Of this fact there is not the slightest doubt. Where none of these causes exist, the fire that consumes the bonds of marriage as tow, is kindled from a spark, the veriest trifle in itself, some unkind or careless word or look, perhaps unnoticed even by the offender. This spark, through our own innate perversity, for I contend that here as elsewhere, in sexual relations, the fault lies generally with the man, or through the malicious or ill-judged meddling of third parties, is fanned into flame, and then the work is done: a separation, with or without the formality of a legal divorce, becomes but too often inevitable, or if not carrying matters to this extent, perhaps for the sake of the children, the parties still live together, united in semblance, but in reality living the most dreary of prison lives, each virtually changed to a foe.
