" While thus enunciating the principle on which the measure of damages for conversion is to be calculated the noble law Lord referred to the statement of Abbott C. J. in Greening vs Wilkinson (supra) and stated: " I should wish to leave open for consideration in a case in which it directly arises the question whether the statement of Abbott C. J. in Greening vs Wilkinson that the jury " may give the value at the time of the conversion or at any subsequent time " can be supported or not." The catena of authorities quoted above shows that but for the reservation made by Lord Porter in the last mentioned case in regard to the statement of Abbott C. J. in Greening vs Wilkinson (supra) the consensus of opinion was that the damages for tort were to be measured as at the date of the tort, though it may be noted that most of these cases were concerned with wrongful conversion of the goods and not with the wrongful detention thereof.
