It must be added to this that we still have to take into consideration not merely the surviving influence of ancient primitive beliefs, but the possible existence of actual nervous conditions during the menstrual period, producing what may be described as an abnormal nervous tension. In this way, we are doubtless concerned with a tissue of phenomena, inextricably woven of folk-lore, autosuggestion, false observation, and real mental and nervous abnormality. Laurent (loc. cit.) has brought forward several cases which may illustrate this point. Thus, he speaks of two young girls of about 16 and 17, slightly neuropathic, but without definite hysterical symptoms, who, during the menstrual period, feel themselves in a sort of electrical state, "with tingling and prickling sensations and feelings of attraction or repulsion at the contact of various objects." These girls believe their garments stick to their skin during the periods; it was only with difficulty that they could remove their slippers, though fitting easily; stockings had to be drawn off violently by another person, and they had given up changing their chemises during the period because the linen became so glued to the skin. An orchestral performer on the double-bass informed Laurent that whenever he left a tuned double-bass in his lodgings during his wife's period a string snapped; consequently he always removed his instrument at this time to a friend's house. He added that the same thing happened two years earlier with a mistress, a _café-concert_ singer, who had, indeed, warned him beforehand. A harpist also informed Laurent that she had been obliged to give up her profession because during her periods several strings of her harp, always the same strings, broke, especially when she was playing. A friend of Laurent's, an official in Cochin China, also told him that the strings of his violin often snapped during the menstrual periods of his Annamite mistress, who informed him that Annamite women are familiar with the phenomenon, and are careful not to play on their instruments at this time. Two young ladies, both good violinists, also affirmed that ever since their first menstruation they had noted a tendency for the strings to snap at this period; one, a genuine artist, who often performed at charity concerts, systematically refused to play at these times, and was often embarrassed to find a pretext; the other, who admitted that she was nervous and irritable at such times, had given up playing on account of the trouble of changing the strings so frequently. Laurent also refers to the frequency with which women break things during the menstrual periods, and considers that this is not simply due to the awkwardness caused by nervous exhaustion or hysterical tremors, but that there is spontaneous breakage. Most usually it happens that a glass breaks when it is being dried with a cloth; needles also break with unusual facility at this time;
