| Popis: | In the autumn of 1918 Dr. J. J. Hood handed to one of us (A. R. L.) eight cultures of yeast, belonging to the late Mr. A. Gordon Salamon. The cultures in question, it appears, were given to Mr. Salamon by the late Prof. Hansen in 1887. They consisted of Freudenreich flasks, containing wads of perfectly dry cotton-wool. The flasks were furnished with a side tube and there was a tube at the apex of each hollow stopper. There was a cotton-wool plug at the opening of each flask inside the hollow stopper, and the tube at the apex of the stopper was plugged with cotton-wool, as was also the side tube. In addition to this, the cotton-wool plug of the side tube was coated with sealing-wax and the hollow stopper was also fixed on with a ring of sealing-wax. Each flask bore a label, giving the name of the particular yeast and the date in Prof. Hansen’s handwriting. The following is a copy of the script on each label:— Sacch. Pastorianus I, Hansen, 17/9/87. Sacch. Pastorianus II, Hansen, 17/9/87. Sacch. Pastorianus III, Hansen, 17/9/87. Sacch. ellipsoideus I, Hansen, 17/9/87. Sacch. ellipsoideus II, Hansen, 17/9/87. Sacch. exiguus, 17/9/87. Sacch. cerevisiæ I, Hansen, 17/9/87. Carlsbberg Unterhefe, No. 2. 17/9/87. |
