โฆ Synopsis
Canadium, a New Metal. ANON. (The Metal Ind., ix, I2, 5o8.) Canadium was discovered by Mr. A. G. French, in a deposit of platinum metals in one of the gold mines in British Columbia. Canadium is sometimes found isolated and sometimes combined. Canadium is a beautiful white metal, a little softer than gold or silver and melts at a little lower temperature. It does not tarnish from damp, and is not affected by sulphides or iodine. It is much more brilliant, when burnished, than silver or palladium. It is electro-negative to silver, gold and palladium, and is not oxidizable even in the oxidizing flame of a blowpipe. It occurs in the form of metallic, semi-crystalline grains, small rods and scales.

## Abstract The author presents a review of the influence of quite a number of organic and inorganic compounds on the corrosion of brasses (70/30, 63/37, 60/40) in several acids (nitric, acetic, lactic, malic, phosphoric and hydrochloric acids), sodium hydroxide, potassium persulfate and ammonium c
## Abstract The carbamate turns out to be a good inhibitor of the corrosion of brass (80/20 and 59/41) in 0.5 N sodium chloride, 1.0 n sodium hydroxide and buffer solutions (NaOH and citric acid, pH 4.4โ6.0). The inhibiting effect depends on inhibitor concentration, so that in some cases corrosion
## Abstract The corrosion of Brass in nitric acid solutions is studied using thermometric, mass loss and polarization methods. The three methods gave almost similar results. The rate of corrosion was found to increase steadily with nitric acid concentration till about 9M where it starts to slow dow
