language, by insisting on "choice," "preference," "esthetic sense," etc. 

There is no need whatever to burden any statement of the actual facts by 

such terms borrowed from human psychology. The female responds to the 

stimulation of the male at the right moment just as the tree responds to 

the stimulation of the warmest days in spring. We should but obscure this 

fact by stating that the tree "chooses" the most beautiful days on which 

to put forth its young sprouts. In explaining the correlation between 

responsive females and accomplished males the supposition of esthetic 

choice is equally unnecessary. It is, however, interesting to observe 

that, though Darwin failed to see that the love-combats, pursuits, dances, 

and parades of the males served as a method of stimulating the impulse of 

contrectation--or, as it would be better to term it, tumescence--in the 

male himself,[23] he to some extent realized the part thus played in 

exciting the equally necessary activity of tumescence in the female. 

 

The justification for using the term "tumescence," which I here 

propose, is to be found in the fact that vascular congestion, 

more especially of the parts related to generation, is an 

essential preliminary to acute sexual desire. This is clearly 

brought out in Heape's careful study of the "sexual season" in 

mammals. Heape distinguishes between the "pro-estrum," or 

preliminary period of congestion, in female animals and the 

immediately following "estrus," or period of desire. The latter 

period is the result of the former, and, among the lower animals 

at all events, intercourse only takes place during the estrus, 

not during the pro-estrum. Tumescence must thus be obtained 

before desire can become acute, and courtship runs _pari passu_ 

with physiological processes. "Normal estrus," Heape states, 

"occurs in conjunction with certain changes in the uterine 

tissue, and this is accompanied by congestion and stimulation or 

irritation of the copulatory organs.... Congestion is invariably 

present and is an essential condition.... The first sign of 

pro-estrum noticed in the lower mammals is a swollen and 

congested vulva and a general restlessness, excitement, or 

uneasiness. There are other signs familiar to breeders of various 

mammals, such as the congested conjunctiva of the rabbit's eye 

and the drooping ears of the pig. Many monkeys exhibit congestion 

of the face and nipples, as well as of the buttocks, thighs, and 

neighboring parts; sometimes they are congested to a very marked 

extent, and in some species a swelling, occasionally prodigious, 

of the soft tissues round the anal and generative openings, which 

is also at the time brilliantly congested, indicates the progress 

of the pro-estrum.... The growth of the stroma-tissue [in the 

uterus of monkeys during the pro-estrum] is rapidly followed by 

an increase in the number and size of the vessels of the stroma; 

the whole becomes richly supplied with blood, and the surface is 

flushed and highly vascular. This process goes on until the whole 

of the internal stroma becomes tense and brilliantly injected 

with blood.... In all essential points the menstruation or 

pro-estrum of the human female is identical with that of 

monkeys.... Estrus is possible only after the changes due to 

pro-estrum have taken place in the uterus. A wave of disturbance, 

at first evident in the external generative organs, extends to 

the uterus, and after the various phases of pro-estrum have been 

gone through in that organ, and the excitement there is 

subsiding, it would seem as if the external organs gain renewed 

stimulus, and it is then that estrus takes place.... In all 

animals which have been investigated coition is not allowed by 

the female until some time after the swelling and congestion of
