In October 1921, I had the honour of submitting to the Institute the results of an investigation into the mortality experienced by life tenants under reversions (J.I.A., vol. liii, pp. 1-42).

The investigation led to certain interesting and, I hope, useful conclusions, among them being the fact that there was no evidence that vendors of reversions exercise selection against purchasers to a significant extent and that in consequence the mortality of life tenants could be sufficiently represented by a full aggregate table.
