![There is, therefore, nothing novel in all this that I have laid before you—nothing, I fear, that Andrew Cameron would have felt was a distinct contribution to practical therapeutics. The complicated act of diagnosing, of localizing, and of removing a brain tumour is based on long- established anatomical and physiological principles, and it is time we paid more attention to a detailed study of the lesions themselves. This will require a more intimate knowledge than we possess of their cellular composition, for which purpose aid must be sought from chemistry and biophysics, all of which merely shows how closely interlocked with other sciences any research in clinical medicine has come to be. And in closing, I would like to quote a state¬ ment made by Ranvier in addressing the histologists in regard to his discovery of the clasmatocytes : Tous savent [he said] que des objets meme tres apparents echappent a leur observation quand ils ne les connaissent pas encore, tandis qu’ils les voient de suite lorsqu’ils ont appris a les observer. C’est pour cela qu’il est si difficile de faire des decouvertes, qui semblent ensuite si simples que l’on se demande s’il y a quelques merites a les avoir faites. Quoi de plus aise que de montrer au- jourdffiui la presence du glycogene dans le foie. Cependant Claude Bernard, qui etait sans conteste un homme de genie, n’y est arrive qu’apres bien des annees de recherches et par une serie de tatonne- ments. BIBLIOGRAPHY 1. Cushing, H.
