The West Indian Inter-Colonial Sanitary Convention, 1904. 
( Presented to both Houses of Parliament by Command of His Majesty, 
November, igoy.) 
I he findings of this Convention, which have been adopted by legislation in 
Barbadoes, Jamaica, Trinidad, British Guiana, St. Vincent and the Leeward 
Islands, although only presented to Parliament, November, 1905, are based 
largely upon the American International Convention of 1903, certain Reports 
of the Public Health and Marine Hospital Service of the United States and 
upon a Report of Dr. Guiteras. They are, therefore, not as recent as the 
findings of the Pan-American International Convention of October, 1905, 
which are framed upon more recent observations (epidemic of 1905). The 
conclusions arrived at by both Conventions are broadly similar ; both 
endeavour to scientifically prevent the spread of Yellow fever and to produce 
the minimum of dislocation of traffic. On the whole, however, the provisions 
of the American International Convention are more rigid, and more precise, 
and I have drawn up a comparison of those Articles in both Conventions 
where differences occur, in order that the advantages or disadvantages, one 
way or the other, may be gauged. I am convinced that a great factor in 
all these quarantine regulations in the eyes of the United States will be the 
power and the equipment which a foreign country possesses to enforce early 
notification and sanitary regulations. 
1. That a Central Quarantine Authority be constituted for the 
West Indian Colonies. 
2. I hat in the opinion of this Conference, the provision by each 
of the Colonies adhering or acceding to the Convention, of an Observation 
Station and an Isolation Hospital, adequate in size and equipment to 
the volume of the passenger traffic in each colony, is indispensable to 
the successful working of a proper precautionary system against the 
introduction of infectious or contagious diseases. 
3. I hat no fees should be charged passengers for medical supervision.
