sulphate or caffeine alkaloid produce a precipitate. However, tincture of digitalis and 

 tincture of strophanthus, in aqueous mixture, each gave slight precipitates, due possibly to 

 free organic acids. — Quantitatively, two volumes of cold infusion of liquorice, British Pharm. 

 will completely precipitate all of the alkaloid in one volume of 1 per cent solution of strychnine 

 hydrochloride. — E. N. Gathercoal.

 — The Soil Improvement Committee has recommended certain standardized fertilizer analyses 

 to be used in connection with the following crops; staple and fodder crops, vegetables, fruits 

 and fertilizers for use in special cases. The percentage of phosphorus, nitrogen and potash 

 to be used in connection with a given soil type are given. An effort is being made to standard- 

 ize all fertilizers sold. — F. M. Schertz.

 Poultry manure should not be used fresh owing to its burning tendency. Better results are 

 secured when dried and stored. Liquid manure is made from it by mixing equal parts with 

 soot, and then using 2 ounces of the mixture to a gallon of water. — J. J. Skinner.

 Jour. Dept. Agric. Victoria 17: 158-163, 217-221. 1919.— Twelve varieties of wheat were 

 tested in one half acre plots. The new crossbred, Gallipoli, produced largest yield, 41 

 bushels per acre. The Selected Federation was next. Glencope produced smallest yield. 

 Fertilizer experiments at Longerenong showed that superphosphate used in amounts of 200 

 pounds per acre produced larger yields than did basic slag, nitrogen fertilizers, lime or manure. 

 The best plot produced 44 bushels per acre. At Warracknabeal 150 pounds of superphosphate 

 produced 25 bushels per acre, this yield being better than that produced by a complete fertil- 

 izer, or phosphate with lime. As small amounts as 30 pounds of superphosphate gave good 

 returns in the New Mallee Areas. Experiments were conducted that data might be secured 

 on early and late sowing. — J. J. Skinner.

 Agric. Victoria 17: 171-173. 1919. — The disease "take all" (Ophiobolus graminis) has devel- 

 oped to a serious extent in the fertilizer plots at the Werribee Research Farm. In each plot 

 where lime was used the disease is present to a greater extent, which seems to indicate that 

 an alkaline soil favors the production of the fungus. The plowing under of green crops favors 

 the development of the disease. — J. J. Skinner.
