Rh The Superior Board of Health of Constantinople shall organize without delay the sanitary establishments of Hanikin and Kisil-Dizie, near Bayazid, upon the Turko-Persian and Turko-Russian frontiers, by means of the funds which are henceforth placed at its disposal.

The other expenses arising, within the jurisdiction of the said Board, in connection with the measures prescribed by the present convention, shall be divided between the Ottoman Government and the Superior Board of Health of Constantinople, in conformity with the understanding reached between the Government and the Powers represented on this Board.

176. In the interest of public health, the High Contracting Parties agree that their representatives in Morocco shall again invite the attention of the International Health Board of Tangier to the necessity of enforcing the provisions of the sanitary conventions.

177. Each Government shall determine the means to be employed for disinfection and for the destruction of rats. The following modes of disinfection are given by way of suggestion:

Old clothing, old rags, infected materials used in dressing wounds, paper, and other objects without value should be destroyed by fire.

Wearing apparel, bedding, and mattresses contaminated by plague bacilli are positively disinfected—

By passing them through a disinfecting chamber using steam under pressure, or through a chamber with flowing steam at 100° C.

By exposure to vapors of formol.

Objects which may, without damage, be immersed in antiseptic solutions (bed covers, underclothes, sheets) may be disinfected by means of solutions of sublimate in the proportion of 1 per 1,000, of phenic acid in the proportion of 3 per 100, of lysol and commercial cresyl in the proportion of 3 per 100, of formol in the proportion of 1 per 100 (one part of the commercial solution of formaldehyde in the proportion of 40 per 100), or by means of alcaline hypochlorites (of soda, potassium) in the proportion of 1 per 100, that is, one part of the usual commercial hypochlorite.

It goes without saying that the time of contact should be long enough to allow dried up germs to be penetrated by the antiseptic solutions, four to six hours being sufficient.

For the destruction of rats three methods are at present employed:

1. That using sulphurous acid mixed with a small quantity of sulphuric anhydride, which is forced under pressure into the holds, stirring the air up. This causes the death of the rats and insects and destroys the plague bacilli at the same time when the content of sulphuro-sulphuric anhydride is sufficiently great.

2. The process by which a noncombustible mixture of carbon monoxid and carbon dioxid is sent into the holds.

3. The process which utilizes carbonic acid in such a way that the content of this gas in the air of the vessel is about 30 per cent.

The last two procedures cause the death of the rodents, but are not claimed to kill the insects and plague bacilli.

The technical committee of the Paris Sanitary Conference of 1903 suggested the following three remedies, viz, a mixture of sulphuro-sulphuric anhydride, a mixture of carbon monoxid and carbonic acid, and carbonic acid, as being among those to which the
