In the last sitting of the Academy of Medicine, in Paris, Professor Jules Cloquet communicated a fetter which he had received, from Teheran, from his nephew, who is physician to the Shah of Persia, in which he gives some interesting details on the subject of the cholera. He says:—" We are threatened with cholera this spring, and I am obliged to do the honors of the country to this disagreeable visitor. The malady in this instance follows a progress quite unusual. It broke out at Bussorah in 1851; it has already come up the course of the Tigris as far as Bagdad; from Bagdad, in crossing the Kurdistan, it directed its course towards the province of Azerbaidian. After having ravaged that country, particularly Tauris, the capital of it, it proceeds to the south and south-east, following the borders of the Caspian Sea, and it is stated that it has made its appearance at Cashin, which is only 22 leagues from Teheran. According to this itinerary, it is not probable that on this occasion it will direct its course towards Europe, and there is every reason to believe that, afterhaving levied its quota on Persia, the malady will proceed to India, its native country, which it ought never to have quitted."
