“SUNLIGHT VITAMIN”
A GERMAN DISCOVERY BERLIN, Oct. 22. “Once more a barricade which opposes research 'into the process of life has fallen.” says Professor F. Mayer, in reporting to the Frankfurter Zei.tung the isolation in pure crystalline form of vitamin D, the “sunlight vitamin,” which prevents Tickets.
This achievement is the work of Professor Windaus, of Gottingen Uni versify, who in 1927 succeeded in extracting from ergosterin, which had been treated with ultra-violet rays, a substance containing a 'large proportion of this particular vitamin. After years'of further work he has been able to free this substance completely from tho by-products of irradiation which it contained, so that the vitamin is left in absolutely uncontaininated condition.
