Another consignment was asked for, but Dr. Hamilton Wright, the 
then Director of the Institute for Medical Research, Kuala Lumpur 
reported in November of that **a further supply i is not available ” 
and that “extensive experiments have been conducted in England an 
United States to test the usefulness of it. "The reports sent in are all 
adverse and unless there is some special reason I do not advise that 
any more be procured." 
RECENT REPORTED SUCCESS IN EUROPE. 
Since the date of Dr. Hamilton Wright's letter, this mode of des- 
troying rats appears to have been аи accomplished i in Euro 
for in the “ Pharmaceutical Journal" of 7th May, 1904, it is stated, 
“ The French Government recently тон АН a series of experiments, 
with the aid of the Pasteur Institute, еа have now sueceeded in 
making a poison, known by the name of the discoverer, Dr. Danysz, 
which, it is claimed, 1s fatal to rats and vo MN : . With the 
object of encouraging the use of this method of destroying the pests,

THE RECENT TRIAL IN PERAK. 
The Directors of the Straits Sugar Company sent out from the 
Pasteur Institute a large consignment of the virus prepared by Dr. 
Dany t was of two kinds, the one being a culture in broth and 
the other in gelatine. 
The cases arrived in Singapore by - French Mail on the 7th 
tember and reached Teluk Anson on the 9th. On the 12th I 
examined the virus and it appeared to be 3 in good condition.

shorter rods, the whole of them being motile. 
The gelatine in the test-tubes had been set on the slant and was 
still solid. It was of a yellowish-brown colour, cloudy, and most of 
the tubes had a greyish-brown sediment. In some tubes there was a 
slight smell resembling that of the broth. The gelatine was neutral 
to test paper. Under the microscope there appeared man y short rods, 
more resembiing cocci, which were not motile, but this was to be 
expected in a solid medium,
