of nine years, to ascertain, with certainty, the effect of the process on various substances. Specimens of English oak, English elm, and Dantzic fir, one ot each prepared with the solution, and one of each unprepared, were placed iu the fungus pit at Woolwich, on the 25th of August, 1836, and taken out on the 15th of July, 1841, when the prepared specimens were found to be perfectly sound, while the unprepared English oak had a spot of fungus on one end, the English elm decayed, and the Dantzic

A quantity of Burnetized deals, with other pieces of the same wood unprepared, were put down in the damp cellar of a house in Chatham Dockyard, where the floors had been repeatedly destroyed by dry-rot, and where large fungi were growing in 1838, and in 1849 all the unprepared wood had become completely rotten, while the Burnetized portion was completely sound, and re]aid with more unprepared deals for further experiment. Six pieces of canvas, and three of woolen cloth prepared, and the like samples unprepared, were placed in a hole four feet deep, in a damp situation, and exposed to the sun, where they remained six months ; they were then taken up, washed in plain water, and dried, then placed in a deal box, and deposited iu a damp sink, but not in contact with water ; they were left in this situatioll lithe weeks, and when examined, the prepared articles were perfect as ever, the unprepared perfectly rotten. These arc a few of the experiments, and which are sufficient to show the nature of the process, and the powerful effects of the solution, which is now universally adopted in Her Majesty's dockyards, and is coming into very general use. In confirmation of the reported good qualities of Sir William Burnett's process, we have had the following letter handed to us:~
