The Adsorption of Radioactive Isotopes on Precipitates
This thesis concerns the investigation of radioisotopes as indicators for precipitation reactions. As a precipitate forms in the presence of a radioisotope, adsorption may take place on its surface. If this adsorption changes markedly at the stoichiometric point it will be possible to use this variation as an indicator for the reaction.

Hydantoins as Anticonvulsants. VIII. 5-Alkylmercapto Derivatives of 3-Methyl-5-Phenylhydantoin
Recent years have seen a rapid increase in the search for new compounds to be employed in the treatment of convulsions associated with epilepsy and related ailments. The properties desired are a higher degree of effectiveness and lower toxicity than those already in use. This thesis describes the effect of methylation of the 5-alkylmercapto-5-phenylhydantoins.

Hydantoins as Anticonvulsants. VI. 5-Substituted-Alkoxy Derivatives of 5-Phenylhydantoin
No derivatives of 5-phenylhydantoin with an oxygen atom attached directly in the five position of the hydantoin nucleus have been found in the literature. It was therefore considered of interest to synthesize a series of compounds of this type to determine the effect of the change of the position of the oxygen atom on anticonvulsant activity.
