| Description | Manuscript lists compiled by Rettie to document his inventions. Some lists are arranged by function—for example, devices for saving lives at sea or preventing mining accidents—while another list provides a general overview of all designs. The numbering Rettie assigned to each invention only occasionally matches the numbers on the reverse of the designs in MS 2381/5. Several designs carry more than one number, some of which correspond to the function‑based lists. |
