As regards the representation of fatigue, the answers have without exception been affirmative. The modes of representation are various. Some feel it (ideally) in the muscles; others under a cerebral form. Here are some examples: “muscular twitchings in the calves of the legs, the back, and the shoulders; the eyes feeling swollen, but no heaviness in the head;” “a feeling of relaxation, of a weight, localised in the shoulders, because, in a normal state, I find stooping very difficult;” “slowness of movement, with a feeling of weight in the head;” “general lassitude, of a diffused kind, especially a feeling of weight in the head, and mental weariness;” “pains in the joints, and a heavy feeling in the brain.” Although all my correspondents can revive the feeling of fatigue, three or four can only succeed in doing so “with difficulty and to a slight extent.” We find the same results with regard to the representation of disgust. I find only three negative answers, all accompanied by the remark, “I have a good digestion.” One of these cases is the more singular because the subject has suffered from sea-sickness. In its acute form the representation is described as “like the beginning of nausea.” For others, it is “a pain in the stomach, with a retractile movement, connected with the idea of cod-liver oil, or of tainted meat.” Among those who have experienced the sensation of sea-sickness, I have not met with one who cannot easily revive it (giddiness, feelings of a rocking motion, which disinclines them to persist in reviving the impression). M. X—— (a very competent observer in psychological questions) says: “I have a pretty good visual memory, but no auditive, either musical or linguistic; I cannot spell a foreign language. Except for muscular memory, which in me is _nil_ (so that I have never succeeded in acquiring any physical exercise, or playing on any instrument), I can revive all internal sensations: hunger, thirst, disgust, fatigue, giddiness, difficulty in breathing; I prefer not to insist upon this last state, as were I to think of it any longer I should actually bring it on.”[101] ----- Footnote 101: A great swimmer has had feelings of suffocation which he can recall with much vividness. ----- 3. _Pains and Pleasures._—To the question, “Can you revive in yourself the memory of a given physical pain, a sorrow, a pleasure, or a pity?” the answer is nearly always in the affirmative. But, put in this bald way, it teaches us nothing. We require more detailed information. We here return to the main point of our subject, and I am obliged slightly to anticipate my conclusions. The observations, carefully taken, show that there are two distinct forms of emotional memory, one _abstract_, the other _concrete_. Later on, I shall insist on their differences; for the moment, I shall confine myself to the enumeration of facts.
