| Description | Written from 16 Great Cumberland Street, Hyde Park, London. The letter gives Wyld's credentials as part of the committee on Sanitary Science at the Society of Arts and mentions his own interest in ventilation which has caused him to write to Brunel about the Great Eastern. The letter comments on a case study of a surgeon named Fleming who ventilated a building of high occupancy in Glasgow with complete success and suggests that a similar system might also be successfully used for the Great Eastern to allow perfect ventilation for the large number of people, either emigrants or soldiers, that Wyld suspects the ship will carry. The letter explains how Wyld thinks this might be achieved at a very low cost and gives the diameter of pipe that Wyld has calculated will be needed. |
