SCIENTIFIC JOTTINGS,.. IVI. Era. Moonier recommends the following method for dying wood of a rose colour by chemical precipitation :—A bath A is prepared with 80 grammes of iodide of potassium per litre of water ; and a bath B in another vessel with 25 grammes of bichloride of mercury. The wood to be dyed is first put into the bath A, where it is left for several hours; it is then dipped into the bath B, when it assumes a beautiful rose colour. The wood thus dyed is afterwards varnished ; the baths will last a long while without any necessity for renewal. M. Payen recommends the following cure for diseased trees and shrubs :—As soon as it perceived that the leaves are turning yellow the earth must be dug up all round the rout within the space of a metre and a half from the stem, and the roots are then watered, twice on the first, and once on the following day, with a solution of 525 grammes of sulphate of iron, 500 of common salt, and 525 of alum in 40 litres of water. This treatment will instill fresh vigour into the sound roots, corrode the bad ones, and restore the health to those which were about to be attacked. The amalgum of sodium as an agent for reducing metals is beginning to attract attention. Mr. C. W. Vincent has obtained an amalgam of chromium by introducing that of sodium into a solution of chloride of chromium, and by subsequent distillation in a retort filled with naphtha vapour the chromium itself is obtained in a finely divided state. Mr. W. B. Giles also has decomposed a saturated solution of pure protochloride of manganese by the amalgum of sodium, whereby an amalgam of manganese was obtained. The mercury of the latter being driven off by the application of heat, remains a brownish-black powder, which appears to bo manganese.  rebellion of '46 ; there was a popular pretender on the cow Only seven years had elapsed since the disastrous tinent, and many intriguers on the alert at home. setting aside this political aspect, and regarding the affair in a businesslike manner, it certainly became the duty o', the officials to examine the contents of the traveller's boxes' since not only did Cognac, Schiedam, and tobacco arrive there in an illicit manner, but French gloves and brocades; Mechlin and Lille laces, and costly trimmings and Celli.' disguises along Point found their way into England under very curious Celestial the valuable t. deePL id pEiernepesireefbyorwnaaymeenftailiecllheinnda, thatplun cgaemde frora firkins of innocent butter, which passed unexam,iline t through a Dashshire custom. house.
