| Description | Written from 18 London Street, City of London. The letter explains that the earlier trial of the steam heater, which caused Brunel great dissatisfaction as to the steam heater's performance, was in no way a good indicator of what the heater can do during its regular work but agrees to some of Brunel's suggestions for alterations to be made to the space heater. The letter updates Brunel on the instructions that have been given with regard to various points of construction for the steam heater, the stuffing boxes, and the fly wheel for the auxiliary engines. |
