Messrs. Davey Paxman & Co., of Colchester, Essex, exhibited 
a vertical "Essex" steam boiler (Art. 3,123) of a somewhat 
novel construction, which is illustrated by fig. 12 on page 212. 
A curved tube, riveted to the crown of tbe fire-tox, conveys the products 
of combustion into a lateral chamber, of triangular section, having flanges by 
which it is secured to the boiler-shell, and furnished, exteriorly, with a door. 
An exactly similar chamber occupies the opposite side of the boiler, and has 
an exit into the chimney. These chambers are connected, one with the 
other, by means of curved horizontal tubes, having a radius somewhat 
greater than that of the boiler shell, so that they can be got into, or out of, 
position without removing either chamber. This arrangement, although 
involving somewhat complex forms in the tube chambers, which are shaped 
in a hydraulic press, gives great accessibility everywhere, and ready means of 
repairing when the tubes, or tube chambers, need overhauling. 
Messrs. Wliitehead & Co., Albert Works, Preston, Lanca- 
shire, showed a new brick-receiving table (Art. 3,127), with side
