TWENTY-NINTH TALK 5«Sl
It seems difficult to Miew, but one mint giCc thrni
the benefit of the dmibt. But at k'a-t therein no
obvious use, mdeedT I think ^e ma} ^» further and
say there is aW)?i2tel\ nn use, in such abomination?.
All vh istctiunists, of course, arc not crwl to th**

ther Ais thing would \\ork, he tritd experiments
upon a number of dogs, the experiment lx;ing simply
to make- a slight incision—to cut this tube and
then to join it in this particular \\ ay. He has told
