WILLIAM THOMSON, 1st BARON KELVIN

ANS, penned at the top of a pre-printed 1896 letter expressing thanks for letters of congratulation on the jubilee of his professorship:  “Dear Rucker  This is for yourself.  I am sending to Sir Douglas an expression of my thanks to the Council for the Address which you brought me from the British Association.  Yours/Kelvin.”  Fine condition, with two mailing folds; a tiny stain at the left edge; and a handling bend in the pre-printed portion.  The British physicist is credited for determining the value of absolute zero.
