140 THE MICROSCOPICAL NEWS. 
MounTING IN Liguip Storax.—Mr. Aylward has sent us some 
slides mounted in the above medium, but as yet we have been 
unable /o see any advantage over the usual mounts in balsam. 
NACHET’s BLacK GrRouND ILLUMINATOR.—If any subscriber 
possesses this accessory, we should be glad of the loan of it: ora 
detailed description would suffice. 
Foot-AND-MouTH Disrase.—There were only 35 fresh out- 
breaks of foot-and-mouth disease in England last week, and of 
these 12 were in Lancashire and 7 in Yorkshire. In twelve other 
counties in which the disease exists there were no fresh outbreaks. 
The total number of infected places in England and Wales is now 
168, a reduction of 1,327 since the beginning of the year, and there 
are now only 2,862 cattle affected with the disease, as compared with 
36,076 on the 4th January. In Lancashire there are now 35 in- 
fected places, with 244 diseased animals upon them ; in Cheshire, 
3 places, 30 animals; in Derbyshire, 5 places, 32 animals. A 
striking improvement has taken place in Norfolk, where, since Jan. 
4, the numbers have been reduced from over 300 infected places 
and 7,000 diseased animals to 4 places and 10 animals. In Lin- 
colnshire there are now only 5 infected places, with 225 diseased 
animals, compared with 124 places and 8,000 diseased animals at 
the beginning of January. The Irish returns for last week are not 
to hand. Scotland continues free. 
THE CHOLERA GERM.—A correspondent writes, ‘“‘ Amongst the 
many productions of that prolific and suggestive writer, Thomas 
Ignatius Maria Foster, is a pamphlet entitled ‘“ Observations on 
some curious and hitherto unnoticed abnormal affections of the 
organs of sense and intellect,” which appeared at Tunbridge Wells 
in 1841. At page 27 there occurs the following passage : ‘ During 
the fine evenings on Sundays and other leisure’ times, several 
scientific friends have been in the habit of assisting me in my ex- 
periments on atmospherical electricity made with the Electric Kite. 
In 1832, when the cholera prevailed in England, a piece of raw 
meat, suspended at the tail of a kite for a few hours, was found to 
come down ina state of putridity, and on one occasion the meat was 
covered with animalcula of an unknown species. Subsequent micros- 
copic researches showed that the secretions of choleraic and other 
sorts of patients were infested with different animalcula. Query: 
may not all diseases have their peculiar insects, which, if they do not 
cause, yet always attend the disorder?’ This brief extract will be 
read with interest at the present moment, when it is claimed that 
the cholera germ has been detected by Dr. Koch.”
