I n the experiment reported here an attempt has been made to determine whether rats offered a free choice between two compound diets, identical except in their starch content and both deficient in the vitamin B complex, would select the one on which they could synthesize the required vitamins by refection. In the process of refection, first investigated by Fridericia (1926), rats are able to ut...

The crystal structure of the title compound, sodium strontium orthoarsenate(V) nona-hydrate, is isotypic with NaSr(PO(4))(H(2)O)(9) and the minerals nabaphite [NaBa(PO(4))(H(2)O)(9)] and nastrophite [Na(Sr,Ba)(PO(4))(H(2)O)(9)]. The Na and Sr atoms are located on threefold rotation axes and are in the centres of slightly distorted Na(H(2)O)(6) octa-hedra and Sr(H(2)O)(9) tricapped trigonal pris...
