Many letters are written in the course of these relationships; Obici and Marchesini have been able to read over 300 such letters which had been carefully preserved by the receivers and which, indeed, formed the chief material for their study.  These letters clearly show that the “flame” most usually arises from a physical sympathy, an admiration of beauty and elegance.  The letters written in this “flame” relationship are full of passion; they appear to be often written during periods of physical excitement and psychic erethism, and may be considered, Obici and Marchesini remark, a form of intellectual onanism, of which the writers afterward feel remorse and shame as of a physically dishonorable act.  In reference to the underlying connection of these feelings with the sexual impulse, one of the lady collaborators writes:  “I can say that a girl who is in love with a man never experiences ‘flame’ emotions for a companion.”

Obici and Marchesini thus summarize the differential character of “flames” as distinguished from ordinary friendships:  “(1) the extraordinary frequency with which, even by means of subterfuges, the lovers exchange letters; (2) the anxiety to see and talk to each other, to press each other’s hands, to embrace and kiss; (3) the long conversations and the very long reveries; (4) persistent jealousy, with its manifold arts and usual results; (5) exaltation of the beloved’s qualities; (6) the habit of writing the beloved’s name everywhere; (7) absence of envy for the loved one’s qualities; (8) the lover’s abnegation in conquering all obstacles to the manifestations of her love; (9) the vanity with which some respond to ‘flame’ declarations; (10) the consciousness of doing a prohibited thing; (11) the pleasure of conquest, of which the trophies (letters, etc.) are preserved.”

The difference between a “flame” and a friendship is very well marked in the absolute exclusiveness of the former, whence arises the possibility of jealousy.  At the same time friendship and love are here woven together.  The letters are chaste (a few exceptions among so many letters not affecting this general rule), and the purity of the flame relationship is also shown by the fact that it is usually between boarders and day-pupils, girls in different classes and different rooms, and seldom between those who are living in close proximity to each other.  “Certainly,” writes one of the lady collaborators, “the first sensual manifestations develop in girls with physical excitement pure and simple, but (at all events, I would wish to believe it) the majority of college-girls find sufficient satisfaction in being as near as possible to the beloved person (of whichever sex), in mutual admiration and in kissing, or, very frequently, in conversation that is by no means moral, though usually very metaphorical.  The object of such conversation is to discover the most important mysteries of human nature, the why and the wherefore; it deals with natural
