818 on a large scale without compulsion. This was the decision taken, by a large majority, at the Tenth International Labour Conference in Geneva in June, 1927, and it was confirmed by the International Conference of Unions of Mutual Benefit Societies and Sickness Insurance Funds which was held in Brussels in October, 1927. The decision of the Conference was in the following terms : " The most effective form of systematic provident effort for preventing and remedying the loss of productive power in the workers consists in compulsory insurance, which may be usefully supplemented by voluntary thrift." It would seem that the function of voluntary insurance in the past has been to explore the ground and prepare the way for large national schemes based on the principle of compulsion, and that its function in the future will be to provide means for voluntary thriftt supplementing the provision made by compulsory
The duration of the disease before the axillary glands become involved is definitely longest in the group of low
histological malignancy, and palliative operations give more prolonged benefit even in advanced cases. It is especially in those cases in which dissemination has occurred, but to a moderate degree, that the value of histology in estimating prognosis is best seen. Of ten such patients belonging to the low and medium malignancy groups, four were alive and
well at the time the records were taken, whereas of eight patients in the high malignancy group there were no survivors. It is to be hoped that Mr. PATEY and Dr. SCARFF will continue their work, for it seems to be based on sound lines and to have definite possibilities. The experimental study of cancer has shown that individual tumours differ from one another in their biological characters, their rate of growth, and their behaviour on transplantation. There is no reason to suppose that the spontaneous insurance: human carcinomata differ from the experimental tumours in all being built to the same pattern; they PROGNOSIS IN MALIGNANT DISEASE. also have their individual character which is more THE results of treatment in malignant disease are, rigid and of greater importance than the reaction called forth in the tissues of the host. The amount on the whole, so unsatisfactory that there is a natural of stroma and the degree of cellular infiltration are tendency to shirk any attempt at prognosis in individual cases. Every surgeon, of course, can of little value in estimating the growth energy of the point to instances where his intervention has been tumour.
