science cannot answer⁠—at present⁠—such as the first problem submitted by Mr L. Bloom ( Pubb. Canv. ) regarding the future determination of sex. Must we accept the view of Empedocles of Trinacria that the right ovary (the postmenstrual period, assert others) is responsible for the birth of males or are the too long neglected spermatozoa or nemasperms the differentiating factors or is it, as most embryologists incline to opine, such as Culpepper, Spallanzani, Blumenbach, Lusk, Hertwig, Leopold and Valenti, a mixture of both. This would be tantamount to a cooperation (one of nature’s favourite devices) between the nisus formativus of the nemasperm on the one hand and on the other a happily chosen position, succubitus felix , of the passive element. The other problem raised by the same inquirer is scarcely less vital: infant mortality. It is interesting because, as he pertinently remarks, we are all born in the same way but we all die in different ways. Mr M. Mulligan ( Hyg. et Eug. Doc. ) blames the sanitary conditions in which our greylunged citizens contract adenoids, pulmonary complaints etc. by inhaling the bacteria which lurk in dust. These factors, he alleges, and the revolting spectacles offered by our streets, hideous publicity posters, religious ministers of all denominations, mutilated soldiers and sailors, exposed scorbutic cardrivers, the suspended carcases of dead animals, paranoic bachelors and unfructified duennas⁠—these, he said, were accountable for any and every fallingoff in the calibre of the race. Kalipedia, he prophesied, would soon be generally adopted and all the graces of life, genuinely good music, agreeable literature, light philosophy, instructive pictures, plastercast reproductions of the classical statues such as Venus and Apollo, artistic coloured photographs of prize babies, all these little attentions would enable ladies who were in a particular condition to pass the intervening months in a most enjoyable manner. Mr J. Crotthers ( Disc. Bacc. ) attributes some of these demises to abdominal trauma in the case of women workers subjected to heavy labours in the workshop and to marital discipline in the home but by far the vast majority to
