18 E. G. & M. E. Carbonate of Soda Nothing perceived. 19 M. G. R. Caraway seeds "It feels like meal--like a seed loaf--caraway seeds." (The _substance_ of the seeds seems to be perceived before their _taste_.) 20 E. G. & M. E. Cloves "Cloves." 21 E. G. & M. E. Citric acid Nothing felt. 22 M. G. R. Do. "Salt." 23 E. G. & M. E. Liquorice "Cloves." 24 M. G. R. Cloves "Cinnamon." 25 E. G. & M. E. Acid jujube "Pear drop." 26 M. G. R. Do. "Something hard, which is giving way--acid jujube." 27 E. G. & M. E. Candied ginger "Something sweet and hot." 28 M. G. R. Do. "Almond toffy." (M. G. took this ginger in the dark, and was some time before he realised that it was ginger.) 29 E. G. & M. E. Home-made Noyau. "Salt." 30 M. G. R. Do. "Port wine." (This was by far the most strongly smelling of the substances tried; the scent of kernels being hard to conceal. Yet it was named by E. as salt.) 31 E. G. & M. E. Bitter aloes "Bitter." 32 M. G. R. Do. Nothing felt. (_Proceedings of the Society for Psychical Research_, vol. ii. pp. 3, 4.) Further experiments in this direction are much to be desired. But apart from the difficulty above referred to, experiments of the kind are liable to be tedious and inconclusive because of the inability of most persons to discriminate accurately between one taste and another, when the guidance of all other senses is lacking. To conduct such experiments to a successful issue, it would probably be necessary that the percipients should have some preliminary training to enable them to distinguish by taste alone between various salts and pharmaceutical preparations. _Transference of Pains._
