Mr. Stainton Moses' most intimate friends were Dr. and Mrs. Stanhope T. Speer. They, with the occasional attendance of another intimate friend, Mr. F. W. Percival, barrister-at-law, and Examiner in the Education Department, were generally the only members of the small group who witnessed the phenomena. Mr. Stainton Moses' note-books had been kept extremely private. It seems probable that no one had seen them until they were placed in Mr. Myers' hands. Two note-books and other MSS. by Dr. Speer were also handed to Mr. Myers, which he says contained independent contemporary records of much evidential value. With regard to Dr. and Mrs. Speer, Mr. Myers says: "Their importance as witnesses of the phenomena is so great, that I must be pardoned for inserting a 'testimonial' to the late Dr. Speer (M.D., Edinburgh), which shall not, however, be in my own words, but in those of Dr. Marshall Hall, F.R.S., one of the best-known physicians of the middle of this century. Writing on 18th March 1849, Dr. Marshall Hall says (in a printed collection of similar testimonials now before me): 'I have great satisfaction in bearing my testimony to the talents and acquirements of Dr. Stanhope Templeman Speer. Dr. Speer has had unusual advantages in having been at the medical schools, not only of London and Edinburgh, but of Paris and Montpellier, and he has availed himself of these advantages with extraordinary diligence and talent. He ranks among our most distinguished rising physicians,'"[40] Dr. Speer practised as a physician at Cheltenham and in London, and at different times held various important hospital posts. He had scientific and artistic tastes, and being possessed of private means, he quitted professional work at the age of thirty-four, and spent his subsequent life in studious retirement. Mr. Myers says that his "cast of mind was strongly materialistic, and it is remarkable that his interest in Mr. Moses' phenomena was from first to last of a purely scientific, as contrasted with an emotional or religious nature."[41] Mrs. Stanhope Speer also kept careful records of the sittings. Over sixty instalments were published in the weekly journal, _Light_, under the title of "Records of Private Seances, from Notes taken at the time of each Sitting."
