Two other stories of precisely the same type--in which a dying mother, earnestly desiring to see her children, falls into a deep sleep, visits them and returns to say that she has done so--are given by Dr. F. G. Lee. In one of them the mother, when dying in Egypt, appears to her children at Torquay, and is clearly seen in broad daylight by all five of the children and also by the nursemaid. (_Glimpses of the Supernatural_, vol. ii., p. 64.) In the other a Quaker lady dying at Cockermouth is clearly seen and recognized in daylight by her three children at Settle, the remainder of the story being practically identical with the one given above. (_Glimpses in the Twilight_, p. 94.) Though these cases appear to be less widely known than that of Mary Goffe, the evidence of their authenticity seems to be quite as good, as will be seen by the attestations obtained by the reverend author of the works from which they are quoted. The man who fully possesses this fourth type of clairvoyance has many and great advantages at his disposal, even in addition to those already mentioned. Not only can he visit without trouble or expense all the beautiful and famous places of the earth, but if he happens to be a scholar, think what it must mean to him that he has access to all the libraries of the world! What must it be for the scientifically-minded man to see taking place before his eyes so many of the processes of the secret chemistry of nature, or for the philosopher to have revealed to him so much more than ever before of the working of the great mysteries of life and death? To him those who are gone from this plane are dead no longer, but living and within reach for a long time to come; for him many of the conceptions of religion are no longer matters of faith, but of knowledge. Above all, he can join the army of invisible helpers, and really be of use on a large scale. Undoubtedly clairvoyance, even when confined to the astral plane, is a great boon to the student. Certainly it has its dangers also, especially for the untrained; danger from evil entities of various kinds, which may terrify or injure those who allow themselves to lose the courage to face them boldly; danger of deception of all sorts, of misconceiving and mis-interpreting what is seen; greatest of all, the danger of becoming conceited about the thing and of thinking it impossible to make a mistake. But a little common-sense and a little experience should easily guard a man against these.
