"I could easily see that she is somewhat bloodless, but I could not see the usual anæmic signs, and by a chance I was actually able to test the quality of her blood, for in opening a window which was stiff a cord gave way, and she cut her hand slightly with broken glass. It was a slight matter in itself, but it gave me an evident chance, and I secured a few drops of the blood and have analysed them. The qualitative analysis gives a quite normal condition, and shows, I should infer, in itself a vigorous state of health. In other physical matters I was quite satisfied that there is no need for anxiety; but as there must be a cause somewhere, I have come to the conclusion that it must be something mental. She complains of difficulty in breathing satisfactorily at times, and of heavy, lethargic sleep, with dreams that frighten her, but regarding which she can remember nothing. She says that as a child she used to walk in her sleep, and that when in Whitby the habit came back, and that once she walked out in the night and went to East Cliff, where Miss Murray found her; but she assures me that of late the habit has not returned. I am in doubt, and so have done the best thing I know of; I have written to my old friend and master, Professor Van Helsing, of Amsterdam, who knows as much about obscure diseases as any one in the world. I have asked him to come over, and as you told me that all things were to be at your charge, I have mentioned to him who you are and your relations to Miss Westenra. This, my dear fellow, is in obedience to your wishes, for I am only too proud and happy to do anything I can for her. Van Helsing would, I know, do anything for me for a personal reason, so, no matter on what ground he comes, we must accept his wishes. He is a seemingly arbitrary man, but this is because he knows what he is talking about better than any one else. He is a philosopher and a metaphysician, and one of the most advanced scientists of his day; and he has, I believe, an absolutely open mind. This, with an iron nerve, a temper of the ice-brook, an indomitable resolution, self-command, and toleration exalted from virtues to blessings, and the kindliest and truest heart that beats--these form his equipment for the noble work that he is doing for mankind--work both in theory and practice, for his views are as wide as his all-embracing sympathy. I tell you these facts that you may know why I have such confidence in him. I have asked him to come at once. I shall see Miss Westenra to-morrow again. She is to meet me at the Stores, so that I may not alarm her mother by too early a repetition of my call.

"Yours always,

"JOHN SEWARD."

"My good Friend,--

"When I have received your letter I am already coming to you. By good fortune I can leave just at once, without wrong to any of those who have trusted me. Were fortune other, then it were bad for those who have trusted, for I come to my friend when he call me to aid those he holds dear. Tell your friend that when that time you suck from my wound so swiftly the poison of the gangrene from that knife that our other friend, too nervous, let slip, you did more for him when he wants my aids and you call for them than all his great fortune could do. But it is pleasure added to do for him, your friend; it is to you that I come. Have then rooms for me at the Great Eastern Hotel, so that I may be near to hand, and please it so arrange that we may see the young lady not too late on to-morrow, for it is likely that I may have to return here that night. But if need be I shall come again in three days, and stay longer if it must. Till then good-bye, my friend John.

"VAN HELSING."
