The reference is to Vol. I., Section 317, Note Z^{a}. The note to which reference is thus made, simply says: "There are two accounts of the remarkable case of the Honourable Mr. Justice Harbottle, one furnished to me by Mrs. Trimmer, of Tunbridge Wells (June, 1805); the other at a much later date, by Anthony Harman, Esq. I much prefer the former; in the first place, because it is minute and detailed, and written, it seems to me, with more caution and knowledge; and in the next, because the letters from Dr. Hedstone, which are embodied in it, furnish matter of the highest value to a right apprehension of the nature of the case. It was one of the best declared cases of an opening of the interior sense, which I have met with. It was affected too, by the phenomenon, which occurs so frequently as to indicate a law of these eccentric conditions; that is to say, it exhibited what I may term, the contagious character of this sort of intrusion of the spirit-world upon the proper domain of matter. So soon as the spirit-action has established itself in the case of one patient, its developed energy begins to radiate, more or less effectually, upon others. The interior vision of the child was opened; as was, also, that of its mother, Mrs. Pyneweck; and both the interior vision and hearing of the scullery-maid, were opened on the same occasion. After-appearances are the result of the law explained in Vol. II., Section 17 to 49. The common centre of association, simultaneously recalled, unites, or _re_unites, as the case may be, for a period measured, as we see, in Section 37. The _maximum_ will extend to days, the _minimum_ is little more than a second. We see the operation of this principle perfectly displayed, in certain cases of lunacy, of epilepsy, of catalepsy, and of mania, of a peculiar and painful character, though unattended by incapacity of business."
