 Condition (iii) is sufficient to distinguish the notion of epistemic transmission from different notions in the neighbourhood. However, as it stands, it is still unsuitable for the purpose to completely characterize the phenomenon of epistemic transmission. The problem is that there are many other cases in which it is intuitive that the justification for p based on e transmits to q even if condition (iii), strictly speaking, is not satisfied. These cases can be described as situations in which only part of the justification that s has for q is based on her justification for p and her knowledge of the entailment from p to q. Consider the following example. Suppose you are travelling on a train heading to Edinburgh. At 16:00, as you enter Newcastle upon Tyne, you spot the train station sign. Then, at 16:05, the ticket controller tells you that you are not yet in Scotland. Now consider the following reasoning:
