| Description | Harrison sends a copy of Yule's paper 'On the influence of bias and of personal equation in statistics of ill-defined qualities'. He explains the cost of copying this work was £2, rather than the 20 shillings originally suggested to Professor Joseph Larmor. Harrison asks how he proposes to deal with the matter, noting that if Yule considered Larmor's figure as definite, and accepted on that basis, he will have to make efforts to obtain the balance from another source. |
