Blom, I.J.B.; Union of South Africa. Dept. of Agriculture; Du Toit, P.J. (Union of South Africa : Dept. of Agriculture, 1934)

Micro-analytical methods for the determination of iodine in biological substances are discussed and the efficiency of the nickel dish method compared with that of the dry oxidation in a closed system. It is shown that under ...
Researches into dips and dipping. A. Lime-sulphur dips. VI. A survey of the behaviour of lime-sulphur dips under field conditions

Hambrock, H.A.; Wilken-Jorden, T.J.; Graf, H.; Union of South Africa. Dept. of Agriculture; Du Toit, P.J. (Union of South Africa : Dept. of Agriculture, 1934)

1. The results of analyses of lime-sulphur dipwashes, the lime and water used in their preparation, received from various parts of the Union, have been summarized and discussed. The samples referred to were all obtained ...
Studies in mineral metabolism XXIX. The iodine content of foodstuffs in relation to the occurrence of endemic goitre in the Langkloof Valley

Blom, I.J.B.; Union of South Africa. Dept. of Agriculture; Du Toit, P.J. (Union of South Africa : Dept. of Agriculture, 1934)

Iodine was determined in foodstuffs from different parts of South Africa including those from endemic goitre areas in the Uniondale district, and such widely differing results were obtained that no fixed relationship could ...
Researches into dips and dipping. D. Effects of dips on wool. Paper I. The effect of arsenical dips on wool

Hambrock, H.A.; Wilken-Jorden, T.J.; Union of South Africa. Dept. of Agriculture; Du Toit, P.J. (Union of South Africa : Dept. of Agriculture, 1934)

The effect of the two arsenical dips, viz.: Cooper's powder dip and sodium arsenite, on the fleece has been studied from several angles. The process of dipping, results in the leaching out of suint constituents, thereby ...
