_Whooping Cough_.—The mortality from this complaint was 45, in the Town sub-district 36, and in Brompton 9. The deaths under five were 44. FEVER.—_Typhus_, was fatal in 9 cases, all in the Town sub-district. The number in the previous year was 6—all likewise in the Town. _Enteric Fever_.—The registered deaths from this disease were 28—viz., 19 in the Town and 9 in Brompton. The numbers in 1873 were 19 and 8 respectively. The term _Typhoid_ is often employed to designate this disease, and leads to error in the tabulation of the mortality returns. I have good reason to believe that some of the cases returned by the Registrar-General as _typhoid fever_ were not cases of _enteric fever_, the word _typhoid_ having been employed in medical certificates of the cause of death to describe a condition of the patient in the last stages of fatal illness of a nature entirely distinct from _enteric fever_. _Simple continued fever_ caused 15 deaths (8 under five years), viz., 11 in the Town sub-district and 4 in Brompton. The deaths in 1873 were 7 and I respectively in the two districts. _Diarrhœa_ was less fatal than in 1873, the deaths being in that year 145, and in 1874 only 112. The annual average number in ten years was 111, without allowances for increase of population. The deaths last year in the two sub-districts were 90 and 22; in the previous year 121 and 24. The large majority of fatal cases occurred in infancy, viz., 100 under one year and 8 between one and five. Above 65 years of age the deaths were 4. At intermediate ages there was no death. The principal mortality was experienced in the warm summer weather, viz., in July 38, and in August 31. Five deaths from _Cholera_ were registered, viz., 3 in the Town and 2 in Brompton. OTHER ZYMOTIC DISEASES.—_Croup_ was the cause of 26 deaths, 25 under five years, and all save one in the Town sub-district. The deaths in the previous year were 20. _Erysipelas_ caused 21 deaths, viz., 13 and 8 in the Town and Brompton respectively. The deaths in 1873 were 24.
