Transvestia

and electroshock on page 59, or concussion on page 63, seemed to trigger off a gender-reversal. (Walin- der cites 10 other cases where concussion did so, and I now have clippings to indicate the LSD and alcohol are capable of this effect.) Only SOME of the experimental subjects so reponded and these would be, it seems reasonable to presume, only those which had the necessary circuits available due to the pre-natal phenomenon of partial brain masculini- zation. Your denial that "TVs can be made" is based on failure to review the literature I have sent you. I might add here that the absence of such circuitry. can be tied to Carl Jung's observation that some men were totally unable to grasp his "Anima" concept; perhaps these represented examples of fully mascu- linized brains, whose rodent counterparts resisted Fisher's experiment.

5-Your long discourse on pages 82-5 on the work of Gorski and others is fine, and well put. I had omitted all that for the sake of brevity, citing only Levine whose papers were the latest references in this series and who has concentrated on the eff- ects in the brain. Your point is well taken that my use of the words "enough male hormone to masculinize part of his brain" was misleading, as the supply is not limited. Let me instead propose that the male hormone from the embryo's gonads arrives too late, after the critical time has passed for A CERTAIN AREA ONLY, and that this area remains un-affected. The known variation of the strength of the TV urge could still be explained by the extent of the un- masculinized area, which in turn could be tied to the length of time lapse beyond the onset of the critical period. To put it on your time scale, one might estimate that the arrival of hormone on the 19th day of pregnancy would produce a male with Amima who could not be feminized by Fisher's inject- ion; delay would cause progressively the fetishist, the TV and finally on the 26th day, the Transexual.
