The careful outlining of procedures and methods is preceded by tures which are used in building up the more complex protein and a valuable review of the literature dealing with polonium and rsr alkaloid structures that amear later in the book. A very short discussion of cyclic compounds, both carhocyclic major portion of the work was done an rats, a few mice, onc raband heterocyclic, consists mainly of introducing basic ring strucbit, and several tracer studies in humans were included. This study led naturally into the discussion of time had to su5ce for the initial pilot experiments. A relatively small number of animals of tional manner with a discussion of the aliphatic hydrocarbons and one species studied at a few dose levels and for a short internal of their derivatives. The organic portion is very complete and begins in the conventechnical assistance, materials, and animals, but more frequently by the pressure of time. The plan and conduct of the directed research under the Man- colloidal and true solutions, ionization, and a romplete discussion hattan District were often determined by the availability of of acids, bases, and salts. The larger portion of this section is devoted to water, -polonium, plutonium, and radium.
