even better results, \iz. the " Victoria," " Baby," " Alpha 
Windsor," and Danish machines. 97'7 per cent, of the total 
butter-fat was removed, and only -087 per cent, of fat left in the 
skim-milk. The loss was slight. As with the " Baby," regu- 
lation of thickness of cream could not be well effected. Naturally, 
omng to the inte^DOsition of the discs, cleaning could not be so 
easily done either. It 
occupied 11 mins, to 
dismantle and clean, 
and one minute to set 
up again, but the clean- 
ing was not done well. 
Still, this and the cost 
would appear to be 
compensated for by the 
larger amount sepa- 
rated. The construc- 
tion of this machine 
was decidedly good, 
and equal to any other. 
To it an equal Second 
Prize with the Danish 
hand machine was 
awarded. 
No. 1239, ''AljyJia 
Windsor," price 281. — 
This was the " Wind- 
sor " machine. No. 
1237, fitted with the 
arrangement of discs 
for which a Silver 
Medal was awarded by 
the Judges of Miscel- 
laneous Implements, 
and which is figured 
on page 524. Instead 
of 32^ gallons being 
separated per hour, 55 
gallons could here be 
done. The expenditure of power was 0-12 horse-power, but 
in respect of efficiency the best result was obtained with this 
machine. Added to this, very effectual separation, and good 
construction, with large quantity of milk separated, combined 
to place the "Alpha Windsor" in the first position. The 
number of revolutions of the handle was 42 to 45, the tern-
