Dairy Implements. — Various clmvns Avcre exhibited both of 
the upright and barrel construction, and havinjr different motions. 
The Society's prize of bl. was given to Mr. William Wood, of 
Knutsford, Cheshire, for the adaptation of a rotative movement to 
work an upright churn. It was ingeniously and conveniently 
managed so as to accommodate a female in the sitting posture. 
Six cheese-presses claimed attention, and two premiums of 3^. 
each were awarded ; one of them to Mr. James Smith, of Glou- 
cester, for a single press, and the other to Mr. Richard Stratton, 
of Bristol, for a double press, invented by Mr. W. James Gingell. 
The first of these Avas furnished with a convenient and excellent 
pressing power, combining the continuous action of the lever with 
that of a screw to elevate it as required, so that the weight has 
never to be released in order to raise the lever. Cleanliness is 
also ensured by furnishing the screw-handles with wooden hafts, 
in order to prevent the dairywoman's hands from touching iron, 
which is represented to be a matter of no slight importance. 
Mr. Gingell's double press is on the same lever principle as his 
single one rewarded at Bristol, but better constructed, and is a 
very neat, compact machine. The Judges, however, are disposed 
to consider the compound screw and lever principle, as arranged 
by Mr. Smith, to possess advantages over any pressing power yet 
exhibited. This plan may possibly be made applicable to the 
double press through the medium of one screw, which would 
diminish the cost, and is a matter worth the consideration of the 
inventor. 
Dynamometer. — A dynamometer on a new construction, invented 
by Mr. Clyburn, was exhibited by the Earl of Ducie. This 
instrument purported to possess new and valuable properties, 
and has been referred by the Council, together with ^lessrs.
