SCIENTIFIC JOTTINGS.-111. Em. Monnier recommends the following method for dying wood of a rose colour by chemical precipitation :—A bath A is prepare& with 80 grammes of iodide of potassium per litre of water's 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, whero it is left for several hours; it is then 1 dipped into the bath B, when it assumes a beautiful ''.one colour. The wood thus dyed is afterwards varnishr,d ; the laths will last a long while without any nectrAity for renewal. M. Payen recommends the following cure for die. eased trees and shrubs :—As soon as it perceived that the leaves are turning yellow the earth must be dur up all round the rout within the space of a met: e and a half from the stem, and the roots are then wat:lred, t,-,,lee on the first" and once , in w-,on the following day, . ... a solution of 525 grammes of sulphate of iron, 500 o- - • ' common salt, and 525 of alum in 40 litres of wa,,ee, 'Chia treatment will instill fresh vigour into the restore the healt' to tteatBe which were about to be attacked.

Only seven years had elapsed since the disastroto rebellion of '45 ; there was a „I PePatar pretender on the con; tinont, and many intriguers on the alert at home. Bil setting aside this political aspect, and regarding the affair r in a businesslike manner, it certainly became the duty n' the officials to examine the contents of the traveller's teaser since not only did Cognac, Schiedam, and tobacco arr::: there in an illicit manner, but French gloves and brocades' Mechlin and Lille laces, and costly trimmings and Cal-s Point found their way into Engl.nd under very curious disguises along our eastern coasts. We know of s° valuable pieces of ornamental china that came from .11 Celestial Empire by way of Holland, plunged deeply firkins of innocent butter, which passed unexera.,holit through a Dashshire custom. house.
