The burial would have taken place with a coroners certificate. Section XXVII An Act for registering Births, Deaths, and Marriages in England. [17 August 1836] 6 & 7 Will. IV. c.86
the Coroner, upon holding any Inquest, may order the Body to be Buried, if he shall think fit, before Registry of the Death, and shall in such Case give a Certificate of his Order in Writing under his Hand, according to the Form of Schedule (F.) to this Act annexed, to such Undertaker or other person having Charge of the Funeral, which shall be delivered as aforesaid;
Sometimes, the precise circumstances of death are only determined at inquest, and a coroner might then be able to give a verdict of natural causes.
