twenty four to thirty six hours. (5) After this is completed,
a final inspection of the crew and passengers of the steam-
er is made by the Health Officer of the Port and if in his
opinion it is safe to release the steamer,she is granted

2. Other places where plague exists:·
The Government, when it comes to their know-
ledge that plague exists in any port in the vicinity of the
Colony, declares the said port to be an infected place and
all vessels arriving from there are sent to the Quarantine
Anchorage, the passengers and crew are examined and if there
has not been any sickness since leaving her last port and
there is not at the time any suspicious case on board the
vessel is then granted pratique.
If there is any infectious disease or any
suspected case of infectious disease on board the procedure
aetailed in the last paragraph is carried out.
The period of incubation of plague is nine
days approximately, and therefore any case on a steamer
leaving India must develope prior to the arrival of the ves
sel at Singapore as all steamers from India leave either
Calcutta or Bombay.
The former is about 9 days and the latter 12
days journey to Singapore and about 15 and 18 respectively
to Hong-Kong.
