| Description | Knott says that he found no sign of mention of the manuscript which Ross sent to P G Tait in 1891 and has asked Mrs Tait if she has any other papers, but she says that she has not. He adds that Tait's son might have taken it to India with him, although he sent back some of his father's correspondence to Knott, and that if it turns up he will send it to Ross. |
