511. Conservative wall, protected hy glass. — A specimen of 

 a wall of this kind is shown in Jigs. 65. and 66., in p. 

 138. and p. 140, which existed, and was found to answer 

 perfectly for upwards of fifteen years, in the garden of Mr. 

 Loudon's house, Porchester-terrace, Bayswater. The appear- 

 ance of this glass-case is shown in the section, jig. 65 at a. 

 The wall was flued, and the glass sashes were fixed in a wooden 

 frame at an angle of about 45°. The wooden frame, resting 

 its upper part against the flued wall, and its lower part being 

 supported by another brick wall, about 18 in. high, about 

 3 ft. from the main wall. The frame was divided into 

 compartments, and the glass sashes pushed along a groove in 

 the lower part of the frame, when it was wished to open them. The sashes 

 were removed altogether in summer.
