This mode of driving creates no vibration, ther efore the machine requires no 
fixing whatever, if it is set level. 
The drum has a partly spherical form, with a neck on the top, and is open 
at the bottom. Inside the drum a diaphragm is formed with a conical open- 
ing in the centre to fix it on the drum spindle. This diaphragm has holes 
round the periphery, forming communications between the upper and lower 
compartments. AVhen the milk is fed into the drum through the feed cup 
in the centre, the separated cream ascends and runs off at the top into a 
circular cover, and the sldm milk, passing into the lower compartment, runs 
off through the opening in the bottom into the fixed receiver in V7hich the 
drum rotates. 
The Judges tried this Separator somewhat under difficulties. 
Owing to the time taken up by the other trials at the Dairy, 
they were not able to try it there, but had to remove it to the 
stand of the Aylesbury Dairy Company, where it was worked 
on the morning of June 27, with the following result : —

From the time the operator ceased working the machine until it 
actually came to rest was 15 minutes 25 seconds, during the 
earlier part of which time separation was taking place. 
Dr. Voelcker reported on the milk as follows : — 
Whole Milk J'S'^f^f^' .... 13 23 per cent.

This Separator, from its simplicity and the ease with which 
it was worked when it had attained its speed, commended itself 
favourably to the J udges, and they would like to have given it 
a more extended and comprehensive trial, but as they were not 
able to do this, they decided to recommend that it may be ex- 
hibited (under Rule 5) as a new implement at the Plymouth 
Meeting of the Society, and classified as an exhibit for special 
inspection. 
Mr. George Hathaway, of Chippenham, exhibited a churn 
(Art. 1541) with a very peculiar motion. He calls it The Uni- 
versal Churn, from the universal motion that is given to it. It
