There can be no doubt of the purity of intention of both Mr Murray and Mr Meek—both since deceased1; the one the imaginary inventor, and the other the staunch advocate, of this mode of heating. It is, however, to be regretted that, in canvassing the merits of the principle, so much ill feeling has prevailed,—and con- sequently error and prejudice have been promulgated, truths have been perverted, and assertions made which had not even the appearance of probability to support them. As a useful mode of heating, our own opinion is unfavourable to it; and we think, had it been designated the Polmaise mode of ventilating, rather than of heating, the title would have been more appropriate. What success may have attended its adoption in the south, we know only by reportthis much, however, we do know, that its utility in the north has not been very great; and, so far as we are aware, there are very few exemplifications of it even up to this time in Scotland. Even with regard to its success at Polmaise—in the neighbour- hood of which, by-the-by, a few years ago, grapes ripened in the open air—we know that the grapes sent to Edinburgh for competition in September were scarcely ripe, although otherwise good-sized fruit, such as might be expected from vines producing from one to three bunches each, and that for the sole purpose of exhibition. Its applications in England, so far as we are aware, have been upon so small a scale, that we can attach but little im- portance to the published results. Hazard's plan of heating is thus de- scribed by him in a communication to " The Gardeners' Chronicle :" — " I send a sketch of a ran
