   1 THE LONG and unprecedented conversation I had with Policeman MacCruiskeen after I##############
   2 went in to him on my mission with the cigarette brought to my mind afterwards several##########
   3 of the more delicate speculations of de Selby, notably his investigation of the nature#########
   4 of time and eternity by a system of mirrors. His theory as I understand it is##################
   5 as follows;####################################################################################
   6 ###############################################################################################
   7 If a man stands before a mirror and sees in it his reflection, what he sees is not a###########
   8 true reproduction of himself but a picture of himself when he was a younger man.###############
   9 de Selby's explanation of this phenomenon is quite simple. Light, as he points out#############
  10 truly enough, has an ascertained and finite rate of travel. Hence before the reflection########
  11 of any object in a mirror can be said to be accomplished, it is necessary that rays of#########
  12 light should first strike the object and subsequently impinge on the glass, to be##############
  13 thrown back again to the object - to the eyes of a man, for instance. There is#################
  14 therefore an appreciable and calculable interval of time between the throwing by a man#########
  15 of a glance at his own face in a mirror and the registration of the reflected image in#########
  16 his eye.#######################################################################################
