'd Represents the increase in length of the axis after exposure to a<irenalin solution for the number of 
tminutes indicate.! to the left in the time column. 
h Time required, for each axis to reach a maximum length. 
It is difficult to deteiToine the relative mydriatic activity of these 
two products by simply compailiig the results obtained vdth eyes 
-from different fi'ogs, for when this is done the inchvidtial variations 
are so great that the general average of the dilation times is about 
the same for like concentrations as is shown by taking an equal 
number of readings from groups of eyes.
