of the flocks to 2,986 animals. During vaccination, and until its 
effects were perfected, 260 sheep out of the whole number of 
33,576 perished. During the same period, the mortality rose to 
366 out of the group of 21,938 which were not vaccinated. When 
the effects of vaccination were complete in the first group the 
mortality from splenic fever fell to five. This rate has persisted up 
to the present time ; and the next statistical account will give, it is 
expected, the same satisfactory results as regards the groups of 
animals vaccinated and left unvaccinated. 
A CoMpRESSOR FOR EIGHTEENPENCE.—Mr. H. E. Forrest has 
devised a Compressorium, which consists of a strong glass plate, 
3in. by 1%{in., with ground edges. A small brass screw passes 
through this plate, the point projecting upwards through it about 
34in. A brass arm, bent so as to form a spring, rotates upon the 
Screw as on a pivot, and carries at one end a brass ring holding a 
thin cover-glass, 1in. in diameter, which covers the centre of the 
plate when in use. A milled nut works upon the screw above the 
arm, and when screwed down brings the cover-glass in contact with 
the glass plate. The spring acts upwards and raises the cover, if 
the nut is unscrewed, so that the two glasses can be fixed at any 
degree of proximity required. 
This accessory may be obtained from Mr. Bolton, of Birmingham, 
at the price above named. 
NATURALISY’S STUDIO ON THE West Coast.—Mr. E. Wade 
Wilton, of Leeds, has issued a circular in which he states that the 
desirability of establishing a Microscopist’s and Naturalist’s Studio, 
devoted largely or entirely to marine organisms, has been shown to 
him; he has recently been asked to open such an establishment on 
the South or West Coasts. He states that during the last two 
years he has received much encouragement in his business as 
Dealer in Living Objects for the Microscope and hopes for a hearty 
response to his appeal. 
The situation chosen is Clovelly on the West Coast, and within 
easy distance of the best collecting grounds both on the West and 
South Coasts. | 
The “Hyproip ZOOPHYTES AND Potyzoa” of these coasts are 
very plentiful and interesting, but owing to the difficulty experienced 
by students in inland places, they have been neglected to a great 
extent ; special attention will be paid to them in their season, viz. : 
Spring and Autumn,
