Royal Dublin Society, May 28. W. J. LOOBY and J. DOYIE: Fertilisation and pro-embryo formation in Sequoia. Fertilisation takes place in Irish material of Sequoia gigantea in August of the first year,being rapidly followed by pro-embryo and early embryo development. The embryo is not completed until the second year, the winter being passed in the embryo-with-suspensor stages. The pro-embryo only occupies the lower part of the archegonium, with wall formation at the eight-nuclei stage, the complete pro-embryo showing a 2-6-6 or a 3-5-5 arrangement. Sequoia sempervirens, though forming a wall at the first division of the fusion nucleus as already recorded, leaves unused protoplasm at the top of the archegonium, the pro-embryo frequently occupying only one half of it. E. J. SHEEHY: Note on the effect of storage on the colour and on the free fatty acid content of a commercial sample of veterinary cod liver oil. Slight hydrolytic and very considerable oxidative changes occurred in veterinary cod liver oil stored under different conditions. Colour changes associated with increased free fatty acid content, and induced by contact with the material of the container, occurred. REPORT or THE IBISH RADIUM COMMITTEE FOB THE YEAR 1934: This includes reports submitted by medical users of radon supplied by the Committee, and records the treatment of 441 malignant and 149 non-malignant cases. This is a considerable increase over the total number (466) recorded in the 1933 report. A tendency towards the use of smaller doses has, however, reduced the total quantity of radon issued from 12.996 mC. in 1933 to 11,744 mC. in 1934.
