Copy letter from Arthur William Rucker, to Edwin Ray Lankester, [Fellow of the Royal Society] A paper by Yale, communicated by Pearson, 'On the Association of Attributes in Statistics, with examples from the material of the Childhood Society &c' has come in. Rucker sent it to Forsyth in the first instance but Forsyth suggests that one biological referee may be desirable. Queries if the abstract will help Lankester decide if it should come before the Zoological Committee. The paper can be seen at the Society or sent. 30 October 1899
