Mina decides to transcribe the journal which Jonathan kept at the Castle Dracula in Transylvania. On the 24th of September, she receives a letter from Dr. Van Helsing asking her if he may discuss Lucy's illness with her. Mina agrees to see him and, that day, Van Helsing arrives. This is the first time that Mina has met Van Helsing, and she gives him Jonathan's journal, which she has finished transcribing. Later that day, Mina receives a note from Van Helsing in which he expresses an intense desire to meet Jonathan. Mina suggests that Van Helsing come for breakfast on the next day.
For the first time in several months, Jonathan Harker begins another diary (or journal). In the new journal, he writes that he is sure that Count Dracula has reached London; in fact, it was the Count whom he saw in Hyde Park. That day Jonathan meets Van Helsing, and the two discuss Jonathan's trip to Transylvania. Just before Van Helsing leaves, he notices an article in the local paper, and he becomes visibly shaken.
Dr. Seward also begins keeping a diary again, even though earlier he had resolved never to do so again. In his diary, Seward notes that Renfield is his same old self — that is, Renfield is back to counting flies and spiders. Seward notes that Arthur seems to be doing well and that Quincey Morris is with him. That very day, in fact, Van Helsing shows him the article in the paper concerning the Bloofer Lady. Van Helsing points out that the injuries to the children are similar to Lucy's neck injury; therefore, the incidents have something in common. Seward is skeptical that there is any connection between the injuries, but Van Helsing berates him, asking him, "Do you not think that there are things that you cannot understand and yet which are; that some people see things that others cannot?" Van Helsing continues to urge Seward to believe in things supernatural, to believe in things which, heretofore, he did not believe in. In desperation, Van Helsing finally tells Seward that the marks on the children "were made by Miss Lucy" (Chapter 15).
