Experiments on the Cobalt Nutrition of Sheep Using Heavy Cobalt Oxide Pellets

Summary 1. Experiments are described in which the effect of dosing lambs with heavy cobalt oxide pellets was studied in (a) the Mourne area and (b) the Antrim plateau area in Northern Ireland. In (a) live-weight increase alone was determined and in (b) a phenothiazine treatment was superimposed and live-weight increases and parasitic worm burdens were investigated. 2. In both areas the cobalt-treated groups made better live-weight gains than the controls. This increase amounted in each case to about 4 lb. per head. In (b) phenothiazine treatment had no effect on body weight. 3. In (b) neither cobalt treatment nor phenothiazine treatment had an appreciable effect on stomach or intestinal worm burdens of the lambs.

A petrochemical study of Tertiary tholeiitic basalts: The middle lavas of the Antrim Plateau

Nine basalts which occur as flows in the Middle Lava series of the Antrim Plateau have been analysed chemically and spectrographically. Seven of the specimens come from the complete flow succession in the neighbourhood of the Giant's Causeway. The petrochemistry of the major and trace elements is discussed.
