the average 1891 1900 for the old Parish of Lambeth.
There is again a marked decrease in the number of Diphtheria
certificates received during 1905, i.e., 38.6 per cent. below the

(1891-1900), and a decrease of 7.2 per cent, from the average
received in the Borough during 1901-4.* The 439 Diphtheria

of these were the drains, on testing, found defective.
The Scarlet Fever notifications were 23.01 per cent. below the

in 13.0 per cent. of these, the drains were, on testing, found
defective.
The Enteric Fever (or Typhoid) notifications received were
59.4 per cent. below the average for 10 years (Parish of Lambeth),
and represent 72 infected houses, of which 12.5 per cent.
of the drains were found, on testing, to be defective.
No cases of plague, nor of suspected plague, nor of cholera have
