On the trial of this cause, the following questions were propounded to the witness Ur. Searles, which were not allowed, and the appellant excepted:
“ "Would you have known of any falling off of Dr. Wylie’s practice, if that had been the case? ”
“ Is the field of practice there so large that you would not have known if there had been a falling off of Dr. Wylie’s practice in the last five or six years? ”
