?408 Regulations against arrivals from [CHAP. XIV. those on which plague has been present within twelve days of arrival. The period of twelve days is arrived at, as in the case of the seven days' period in the Convention of 1892, by adding two days to the period of incubation. Healthy ships pass the Canal in quarantine. A healthy vessel thus becomes entitled to free pratique at a port at which it arrives ten days or more after leaving an infected port, but the adoption of this period has the serious result that fast vessels sailing from Bombay arrive at the Suez Canal before pratique can be granted. This difficulty has been satisfactorily overcome by permitting healthy vessels to pass through the Canal in quarantine and to complete in the Mediterranean the ten days necessary to receiving free pratique at a port of arrival. Vessels passing through the Canal in quarantine may, subject to the use of electric light, coal in quarantine at Port Said by night as well as by day, and passengers may embark in quarantine at that port. Infected and suspected ships. The rules for infected and suspected ships follow those of the Venice Convention of 1892.

Vessels without a doctor and disinfecting stove are detained at Moses's Well. Such vessels if suspected are detained for the period required for disinfection and for ascertain- ing the condition of the ship's health, while, if infected, the pas- sengers are detained on shore under observation for a maximum period of ten days. The segregation accommodation and the medi- cal and sanitary staff at Moses's Wells are being increased for the purpose of carrying out these regulations. The Egyptian Sanitary Board issued revised plague regulations on the lines of the Convention regulations described above. UNITED KINGDOM. Local Government Board Rules of November 1896. In the United Kingdom arrivals from infected Indian ports were dealt with under the "General Regulations as to Cholera, Yellow Fever and Plague" issued by the Local Government Board on the 9th November 1896. These regulations, which are based on advanced scientific principles, offer practically no hindrance to communication with India. Healthy ships, Infected ships.
