INCIDENCE OF ANTHRAX IN STOCK IN AUSTRALIA, al 
s 
In Victoria, during the years 1909 to 1921, out of 40 out- 
breaks regarded as undoubtedly Anthrax, the distribution 
was as follows: — 
January 3 July 4 
February 7 August 3 
March D September 2 
April 6 October 1 
May 1 November 2 
June 4 December 2 
From this it will be seen that the Victorian figures rather

The difference in the two States might be thought to be 
due to the degree of settlement which had taken place 
with its consequent change in the methods of animal 
husbandry, and this may be the explanation. Briefly the 
Maximum period of danger from Anthrax in Australia is 
the summer and early autumn. This fact will receive 
support if some of the figures dealing with vaccination as: 
a preventive are noted. In 1917 vaccination is recorded 
as having been carried out on 260 holdings, and the vac- 
cination was distributed throughout the year as follows:— 
January 44 August 2 
February 46 September 1 
March 22 October 40 
April 5 November D1 
May 2 December 46 
June 1 —— 
July 0 Total 260 
In 1914 33 holdings were quarantined on account of 
preventive inoculation; of these 20 were quarantined in 
January, 2 in February, 1 in March, 1 in October, 4 in 
November, 5in December. The 1912 figuresread: January 
25, February 1, March 1, September 4, October 25, Novem- 
ber 23, December 23. Other years’ records bear out these 
figures. Now if, as Norris held, spring and early summer
