The Paxton Hot-Houses. — Allusion has been made in this journal to one 

 form of patent hot-house, — that invented by Mr. Beard. We now invite attention 

 to another patented form of structure, for which the gardening world is indebted 

 to the ingenuity of the late Sir Joseph Paxton, and which was contrived by him 

 specially to secure, as it most amply does, the two great desiderata of cheapness

 by narrow sashes (divided in halves) hinged to one side, thus forming ventilators 

 alternately with the large sashes, and opening by means of a stay pushed up 

 from the inside, either the upper half separately, or when joined by a catch to 

 the lower half, as one long ventilator. This will be understood on reference tc 

 the figure, which represents the upper-half ventilator open to full extent, and the 

 lower half closed ; the iron bar connecting large sashes {a) ; the stay {b) by which 

 the ventilator can be opened quite wide, or with the smallest aperture on one 

 side only ; and the catch {c) for joining the two portions as one. These ventila- 

 tors may be hinged on the right and left sides alternately for lean-to roofs, to avoid
