Researches into dips and dipping. A. Lime-sulphur dips. Paper IV. Further studies on the colorimetric method as a rapid means of control of polysulphide solutions

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

As a continuation of the preliminary study of the colorimetric method as a rapid means of control of polysulphide solutions, the effect of free alkali on sodium polysulphide solutions at room temperature was studied, since ...
Researches into dips and dipping. A. Lime-sulphur dips. Paper V. The minimum effective concentration of lime-sulphur dips for sheep scab eradication

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

The tests demonstrate that lime-sulphur dips used at a strength varying between 0.9 and 0.3 per cent. polysulphide sulphur may be effective in curing sheep of scab when badly infected. When used at a lower concentration ...
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 ...
Researches into dips and dipping. C. Miscellaneous : the effect of dosing aloes to tick-infected cattle

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

The tests demonstrated that single doses of from 8 to 15 dr. aloes and daily doses for five days of from 30 to 60 gm. aloes to cattle do not cause ticks to leave their hosts, and no dead ticks were found on the animals. ...
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 ...
Studies on the origin of the sulphur in wool. I. A study of the Sullivan technique for cystine

Rossouw, S.D.; Wilken-Jorden, T.J.; Union of South Africa. Dept. of Agriculture; Du Toit, P.J. (Union of South Africa : Dept. of Agriculture, 1934)

It has been shown that the Sullivan reaction as a quantitative colorimetric method for the determination of cystine can be considerably improved by better regulation of the conditions necessary for optimum maximum colour ...
