This provifion in the artificial climate may perhaps be found as ufeful as the regulation of its temperature, or the admifiion of light, for promoting the growth ol vegetables, and is therefore a fubject deferving of much attention. Be fide furnifhing the dove with a perpetual fuccef- don of air, warmed, but not vitiated by the fire, it is further requifite to prov’de for the regular difcharge of that which has been vitiated by the plants. / l * The caps of the glafs are fuppofed to admit a quantity of air fuflicicnt to prevent 2ny ftagnation of putrid effluvia. Mr. Whitehurft, however, thought that cold ftreams of air thus admitted muff be injurious to the plants, at lea ft in very fmall ftoves; he therefore recommended that the windows fhould be con- fire £1 d as nearly air-tight as poilible, and that a diftinft mode of ventilation fhould be applied, by which the air might be made warm before its entrance into the ffovc, ft
