TitleLetter from J [Joseph] Larmor, Helen's Bay, Belfast, to A J [Alfred James] Ewart
CreatorLarmor; Sir Joseph (1857-1942); Irish theoretical physicist
RecipientEwart; Alfred James (1872-1937); British botanist
Date23 April 1905
DescriptionHe got a proof of Ewart's paper on sap ['The ascent of water in trees'] to see if he make his points clearer in print. He cannot see Ewart's difficulties but thinks the way he gets over them may involve contradictions of facts. He cannot see why the weight of the contents of each vessel is not supported mainly by its own walls and transverse boundaries. He sees no evidence that transpiration upward through a partitition, from one vessel to a higher one with greater concentration, is the same amount as the flow from water through the partition. He gives a small diagram to express his meaning. Larmor thinks the curious things which Ewart called Jamin's chains seem to work by viscosity, more than by surface tension. Larmor concludes by asking for the return of his letter.
