Letter from W T [William Turner] Thiselton-Dyer, Kew, to [Joseph] Larmor He would not have troubled Larmor if he had known that [John] Joly had written to him. Thiselton-Dyer was unable to hear Ewart's paper and cannot fnd an abstract. He discusses Joly's and Dixon's point on the replacement of water at the surface of a plant setting up tensile strain on the water columns, a new idea to botanists which produced an animated discussion. The Royal Society has been occupied with water movement in plants for two centuries. He sees no objection to the course Larmor recommends for Hartog's paper, as it had not occurred to him that Hartog proposed to publish everything on the screen. It is one thing to fully illustrate a talk, quite another to have significant illustrations to a written paper. Biological papers are often too profusely illustrated. He notes Hartog's main point, which does not require much illustration, and he thinks the Proceedings is the proper place for Hartog. 1 February 1905
