764 Report on the Trial of Railway- Waggons 
IS first to remove the animal heat as speedily as possible ; there- 
fore he would place the meat in the vans immediately after 
death, and if any droppings take place, the same are collected in 
a small well, which has an air-tight plug, so that the liquid can 
be easily and speedily removed. 
No. 2. Kennard Knott's Patent Meat- Van, manufactured hy the 
Sioansea Waggon Company. — This waggon, like the other, is con- 
structed to be air-tight, but, instead of fresh air being drawn in, 
the air contained in the chamber is used over and over again, being 
purified, dried, and cooled. The action is set up by means of a 
blower, which is worked from the axle of the carriage when the 
latter is in motion, and which can be made to revolve by manual 
labour if desirable. A tube communicating with the blower is 
fixed on one side under the top of the waggon. This tube has a 
number of holes. The air from the chamber is drawn by this 
means into a receptacle filled with charcoal, and circulates thence 
through a series of vertical tubes which are surrounded by ice. 
The temperature is thus reduced and the air dried. The mouths 
of the tubes open into the chamber ; their upper orifices com- 
municate with a jacket ; but there is a false ceiling to the meat- 
chamber formed of boards, and so arranged that any moisture 
which condenses on the surface of the wood, finds its way into 
channels on each side and escapes. All these arrangements 
were very rough, and admit of improvement. The air, after 
circulation through the tubes, is discharged into the chamber 
at the opposite end to that from which it is sucked up. By 
using a mixture of ice and salt, about one-third of the latter, 
a greater degree of cold is produced than with ice alone. The 
drawings do not represent the same arrangement as regards the 
tubes, &c., as in the waggon which was tried. Owing to the 
position of the tubes, a considerable time was occupied in 
filling the ice-chamber, the ice having to be broken very small 
in order to pass between the tubes. The waggon is made of 
i-in. deal boards outside, then two inches space filled with 
charcoal, and ^-in. boards inside. The interior is not lined, 
and there was no provision for removing or collecting drippings. 
The arrangements for hanging the meat were very rude. It 
should be noted that this waggon is mounted on carriage springs, 
so that it can be attached to passenger trains running at a high 
speed, whicli is not the case with Colonel Mann's waggon, which 
has the ordinary waggon springs. 
The Judges, Messrs. Wheatley, Fowler, and Tindall, and the 
official reporter, met at Hanover Square, on Thursday, May 29, 
and decided that the Society should provide the following 
quantities and varieties of stores for each van ; and it was
