With the view of testing to what extent an interchange took place between the perpetrators of the four major crimes I have prepared a return of 370 convicts and long-term prisoners in Scotland, convicted of (i) homicides, assaults, etc.; (2) crimes against property with violence; and (3) vjitliout violence; and (4) crimes against chastity.
