Health District III.—Victoria.
In this district also the Table and curves shew the tailing off of the 1903 epizootic and epidemic.
Two cases of plague occurred in the 46th week, 1903, although no infected rats were found from the 40th to 52nd weeks of the year.
The period during which the rats appear to be more or less continuously affected in 1904 begins in the 5th week, 1904, and extends to the 28th week, but with the exception of an isolated case of plague in the 6th week no epidemic appears until the 19th week.
Health Districts IV to VIII.-Victoria.
This being a combined district one sees a rat curve of somewhat similar nature to that for the whole City. It presents a series of waves, practically five, while the epidemic curve presents only two such.
We have the tail end of the 1903 epizootic and epidemic and some isolated cases of plague occurring close on the second and fourth epizootic waves, but their appearance is not constant in point of time.
The curve of the epidemic period 1904 cannot be said to follow a marked rise in the epizootic curve. The two curves are practically synchronous.
