were the seasons of greatest prevalence, the bulk of the 
vaccination would not be carried out from October to. 
February, but from July to October. 
Norris appears to have based his dictum on the alleged 
fact that spring and early summer is a wet period of the 
year, but this is not borne out by the Statistical Register 
for New South Wales, and it was obvious that such a state- 
ment could not possibly be made for the whole of the con- 
tinent. From the Statistical Register for 1918-19 the 
following figures are taken representing the average rain- 
fall in each month for the years 1907 — 1918 for six typical 
localities within the Anthrax belt.

If this table be compared with the monthly record of 
outbreaks on page 50 it will be seen that there is not any 
very marked connection between outbreaks and rainfall, 
April the driest month of all having as many outbreaks as 
November, while June, July and August, months of com- 
paratively heavy rainfall are very free from Anthrax. 
September and October, the two typical spring months are _ 
not markedly wet. 
Localisation of Anthrax. | 
In spite of the fact that Anthrax has existed for so many 
years in Australia, it has remained curiously localised. At 
the present moment New South Wales is unquestionably 
the State which suffers most severely from Anthrax, but
