Direct vs Indirect
THIS IS REALLY NOW THE SUMMARY! All mixed up again!
In formulating ideas about a hypothetical resonanting device in the
thorax we have not clearly distinguished the various alternative developments
that need to be considered, sincis is only theory and all recognized
possiblities must be weighed.
1. There is one resonating device onvolved: vubrating membrane
2. There are two muscular systems involved: The dorsoventral and dorso-longitudinal
muscles activating a click action-type multivibrator. This would may
be at audio frquencies or below it, and sounding more like a pulse
or a train of pulses. At the same time
Clearup Again
Prposing this idea of a resonantor basis for flight, we are can only
take general views of things.
We cannot HUMID day again, i am tired !! not much of a thinking
