...preacher conducting morning services will be found in Wadsworth House 1 every morning during his term of service from 9 to 11 o'clock...
...method of experimentation is complicated. The experiments were carried out with the greatest thoroughness, especial care being taken to have the materials as pure as possible. The results of the investigation were amazing. It was found that all of the radioactive speciments, obtained from uraninite, carnotite and thorianite, exhibited a lower atomic weight than ordinary lead, as determined under identical conditions, the deficiency in one case amounting to as much as 0.75 of a unit...
...simple linear quantitative relationship between the exact amount of radioactivity and the atomic weight was found. The ultra-violet spectrum of a typical specimen appeared to be exactly identical with that of ordinary lead. The necessary inference seems to be that lead from radioactive sources consists of a mixture of at least two substances, of which one is ordinary lead. The foreign substance must be very similar to ordinary lead and very difficult if not impossible to eliminate by chemical means; for many precautions were taken to purify the samples. This substance cannot be identified in the ultra-violet spectrum...
...University Tea, on Christmas Day, but on Friday, January 1, the regular Tea will be held in the Parlor of Phillips Brooks House. On account of the large number of professors who do not know whether they will be in Cambridge at that time, the committee has found it impossible to make out a definite list of those who will be present. The regular committee, Mrs. C. Palache, Mrs. R. Thaxter, Mrs. Joseph Warren and Mrs. H. A. Yeomans, will receive and it is assured that several others will also attend. It is hoped that those men who remain...
