HEALTH OF LONDON.  (From the Registrar-Generar TPeekly Return) Tho mortality of London is still much in excess. In the week that ended last Saturday the deaths were 1,408, and showed hardly any decrease on the return of the previous weEk. The average number of deaths for the corresponding week in each of the last ten years-1853 62, after correction for increasing population, was 1 286 ; and the return of last week was, therefore, greater by 122 than it would have been if the rate of mortality had been equal to the average. The births were 555 more than the deaths. There were 65 deaths from smallpox last week. The mortality from this disease, which rose considerably in the beginning of the present month, has varied little during the last three weeks. There were comparatively few deaths from it in the districts on the south side of the river. None were recorded in the week in the Holborn and Clerken well districts, and none in Shereditch, Camberwell, Greenwich, or Lewisham. There were 7 deaths from smallpox in the district of St. George, Hanover• square, 6 i❑ Westminster. 4 in St. Giles, 4in St. Botolph. In a house, 12, Pell-street, St. George-in-the East, 7 persons are or have been suffering from smallpox. The registrar of the subdistrict (St. Mary) had been informed that it was particularly prevalent among German sugar-bakers and their families. There were 65 deaths from scarlatina (the same number as that of smallpox), 4 of which were in St. Botolpb, and 9 in the district of Whitechapel. Measles was fatal in 58 cases, 10 of which occurred in Chelsea, 6 in the Trinity subdistrict of Newington.  A woman died from typhus at 7, York-place, Sr. Martin-in-the-Fields, and also another woman at 15, York-place. Mr. Leonard, surgeon and registrar, states that these persons were sisters•in-law ; that " the house, 15, York•place, is the worst in the parish, and that he has sent six cases to the Fever Hospital from a room under the tiles." He adds, " I had to get out on the roof, cross the leads, and get through a hole about three feet square, the only means of ingress."  Seven murders were registered in the week.
