"She came in slowly, unhurriedly, perhaps a little amused at the amazement she saw written on my face. I starred, open-mouthed ... she was beautiful, though of a different type of beauty compared with that of the women I have known. Her hair was blonde, nearly white (like hair dyed in peroxide)—it was smooth, not very thick, with a part in the center and she had big blue eyes, rather longer than round, for they slanted outward, like those pencil-drawn girls made to look like Arabian princesses, that look as if they were slit ... except that they were natural; there was no makeup. Her nose was straight, not pointed, not turned-up, nor too big. The contour of her face was different, though, because she had very high, prominent cheekbones that made her face narrowed to a peak, so that all of a sudden it ended in a pointed chin, which gave the lower part of her face a very pointed look. Her lips were very thin, nearly invisible in fact. Her ears, which I only saw later, were small and did not seem different from ordinary ears. Her high cheekbones gave one the impression that there was a broken bone somewhere underneath, but as I discovered later, they were soft and fleshy to the touch, so they did not seem to made of bone. Her body was much more beautiful than any I had ever seen before. It was slim, and her breasts stood up high and well-separated. Her waistline was thin, her belly flat, her hips well-developed, and her thighs were large. Her feet were small, her hands long and narrow. Her fingers and nails were normal. She was much shorter than I am, her head only reached my shoulder ... Her skin was white (as that of our fair woman here) and she was full of freckles on her arms. I didn't notice any perfume ... except for a natural female odor ... And another thing I noticed was the hair in her armpits was bright red, nearly the color of blood." Bruce Rux points out that "a later recounting of Boas's story included the mention that her pubic hair was also bright red, which may have omitted from the original publication of Boas' encounter due to the sexual mores of the time. Details of his encounter which followed were not published either, but apparently he did discuss them—albeit with some embarrassment—when relating his story to Dr. Fontes and Mr. Martins."

Boas recounts that the woman came toward him "in silence looking at me all the while as if she wanted something from me." Pressing herself to him, he understood what her purpose was. "I began to get excited ... I ended up forgetting everything and held the woman close to me, corresponding to her favors with greater ones of my own." Apparently, they had two sexual encounters and performed a variety of acts together for about an hour, after which the woman pulled away to leave. "[A]ll they wanted [was] a good stallion to improve their stock," Boas would say. He said that he enjoyed the encounter, even if the woman refused to kiss. Bruce Rux remarked that after all, he had just thrown up. Instead the "woman" preferred to bite his chin, while making sounds, that in Boas' mind, sounded like "animal growls." She never spoke. When they were finished , one of the other creatures entered and called out to the woman. "But before leaving, she pointed to her belly, and smilingly (as well as she could smile) pointed to the sky—southward, I should say. Then she went away. I interpreted the signs as meaning to say that she intended to return and take me with her to wherever it was she lived." He seem to be concerned, or even afraid about the last, "for he took the meaning quite seriously and wasn't sure if he was anxious to leave his familiar surroundings or his family," Rux writes...
