Experiments are described in which fingernails were taken from 5 volunteers who had been given a therapeutic dose of arsenious oxide. Fingernail clippings taken over a period of 180 days from the date of ingestion were analysed for arsenic by neutron

Ethane is the only alkane which exhibits structure in its molecular electronic absorption spectrum. High resolution photographs reveal that this is diffuse vibrational structure in the case of C 2 H 6 . However, the 0-0 band of C 2 D 6 , near 1406 A,

The radionuclides phosphorus-32, arsenic-74, iron-59 and molybdenum-99 were used to determine the effect-of arsenate and some transition-metal ions on the precipitation of phosphorus as ammonium 12-molybdophosphate. Under the conditions necessary for

Two panes of glass, 3ft. x 2ft., have been examined for heterogeneity. The density and refractive index of variously sized samples of glass were measured over a pane using a number of different methods. The results obtained from each method are compa

The precipitation of phosphate with quinolinium molybdate was studied by means of radioactive tracers, in relation to the excess of reagent, temperature of precipitation, etc. Precipitation is almost quantitative (99.3%) even with a stoichiometric am

The uptake of arsenic over a period of about one year in the head hair of a person taking known therapeutic amounts of Fowler's solution is studied using neutron activation analysis. The work supports the view that where arsenic is administered over
