There is no doubt that the establishment of these clinics is one of the most important parts in the work of a Birth Control League. The written word and written directions are very good, but the fact remains that even the best educated women have very limited knowledge of the construction of their generative organs or their physiology. What, then, can be expected of the less educated women, who have had less advantages and opportunities? It is consequently most desirable that there be practical teaching of the methods to be recommended, and women taught the physiology of their sex organs by those equipped with the knowledge and capable of teaching it. The Neo-Malthusian League of Holland endorses, as the most reliable means of prevention of conception, the Mensinger pessary (which differs in construction from the French or the American Mizpah pessary). The nurses also recommend this; but other methods are discussed with the patient, and the husband’s attitude toward other methods considered and discussed. The pessary is the commonest recommendation, as giving the most satisfactory results. RESULTS. It stands to the credit of Holland that it is perhaps the only country where the advocates of Birth Control have not been prosecuted or jailed. This does not mean there has been no opposition to this propaganda; on the contrary, there is to-day strong opposition by the Church, and only a few years ago, in 1911, when a Clerical Government came into power, laws were made against the propagation of these ideas, and much of the freedom previously enjoyed by the League was denied it; but on the expulsion of the Clerical Government later on, the rights of free speech and free press were regained. In the year 1895 the League was given a royal decree of public utility, which again does not necessarily mean this propaganda is sanctioned by the Government; but the laws regarding the liberty of the individual and the freedom of the press uphold it, and it is thus that its advocates are not molested. The League has thirty sub-divisions, which include all the large cities and towns and many of the smaller ones. Over 7,000 pamphlets of the kind printed herein are sent out in the Dutch language and several hundred in English and Esperanto each year. These are only sent when asked for by the applicant. There is no doubt that the Neo-Malthusian League of Holland stands as the foremost in the world in organisation, and also as a practical example of the results to be obtained from Birth Control teaching. Aside from the spreading influence of these ideas in Belgium, Italy, and Germany, Holland presents to the world a statistical record which proves unmistakeably what the advocates of Birth Control have claimed for it.
