FIRST INTERNATIONAL SYMPOSIUM 403 ments on the uptake of radioactive glucose and of radioactive cystine. The former is apparently absorbed predominantly by the hair bulb while the latter appears to enter higher up, just below the region of keratiniza- tion. Then followed a lecture by Dr. J. B. Hamilton (New York), who discussed what are evidently genetic differences in the rate of hair growth in Caucasian and Japanese men and women. The final afternoon began with a review by Dr. M.P. Mohn (New York) of the effects on rat hair growth of the hormones of the gonads, adrenal, pituitary, thyroid and islets of Langerhans. Inhibitory effects were de- scribed with the use of oestrogens, glucocorticoids, adrenalin and adreno- i corticotrophic hormone. stimulus was obtain with thyrofanendedtheorytheLondon) insulin. Other hormones were without effect. Some The symposium with a description by Dr. R. E. Billingham (University College, the de novo formation of follicles in the adult. In disproving that such new formation never occurs, he gave details of follicle production in the rabbit when a large wound is resurfaced with new epidermis, and in the deer during the annual production of new antlers. However, he pointed out that in normal adult mammals there is no evidence that this process ever occurs. The symposium was clearly a great success and all those connected with its organization are to be highly congratulated. Under the general editor- ship of Prof. Montagna the various contributions are now to be collected and published in book form, and the result should be an invaluable review of the present state of knowledge of hair growth.
