** Regarding date, time and place of death, probably most people died at home, or at a relative's house. With few antiseptics, a broken leg or similar problem could be fatal through infection getting into an open wound.

Again, many older people died not from their initial medical
problem, but from pneumonia - which my doctor father-in-law called "the old man's friend", as it was a relatively painless death.

Dying in a hospital was not common - partly because in the 19th centurymost of the population regarded going into hospital as a death sentence!

The doctor was usually called during daytime, simply to certify death and thus allow a relative to go to the registrar. The doctor was probably not present at the death, but the death certificate informant probably was (and the certificate would say: (present))

Cause of death in the early years of registration was not structured by the registrar general, and so you find causes such as "infirmities of infancy", "Infirmities of old age" and similar bland wordings which do not state a real medical cause of death. By the early 20th century, the Registration system started demanding formal medical causes of death, and things improved.
