cator to the countersliaft of his machine, the extra power taken 
by this small instrument was clearly shown. There has always 
been some difficulty in getting a good record of small powers 
by existing dynamometers, and this plan seems to be a good 
solution of the difficulties hitherto experienced. It was tried 
by the Society for the first time on this occasion, at the sugges- 
tion of Mr. Neville Grenville, and although some exhibitors 
made an objection to it, through a technicality in the applica- 
tion not quite agreeing with the printed conditions of the trial, 
yet in the end it proved most satisfactory, and far superior to 
the old hand dynamometer. The latter was also used for the 
satisfaction of any objectors to the new system. 
It remains to compare the results and to mention other 
points which influenced the Judges in determining the destination 
of the awards in either class. 
Class II. Power Machines. 
A measured run of from twenty to thirty minutes was given 
to each machine on June 18, the separated products being 
■weighed and the skim^milk analysed. In other trials given 
subsequently the power and other factors were determined. For 
convenience of comparison the results of separation are stated 
for the hour and in percentages, the temperatures in degrees 
Fahrenheit. The loSs includes what was left in the drum 
and bowl of the machine, and thus in giving the amount per 
hour this has been multiplied, for there would in reality not be 
more than one and the same quantity at the end of the hour than 
after a lesser period. 
No. 957, The " Fic^oW«," price 40L — This machine separated 
in the hour about 90 gallons, the smallest quantity of the five 
competing machines. The power required was 1*91 h.p., which 
was fair, but the efficiency of this machine was not so high as 
that of any of the others. The number of revolutions was 7,500 
per minute, and the temperature of separation from 92° to 96° 
Fahr. The separation, however, was, along with that of the 
" Reading Royal " machine, the most perfect, 97'2 per cent, of 
the butter-fat of the whole-milk being removed, and only O'll 
per cent, of the fat being left in the skim-milk. The loss also 
was very small, the bowl, as exi^lained before, emptying itself 
completely. In power of regulating the thickness of cream, all 
the machines, with the exception of the Danish one. No. 4294, 
were about on a par, and effected this fairly. The Danish 
machine was decidedly superior in this respect. The " Victoria "
