When are you actually going to READ WHAT MILLER WROTE????

My Fig. 1, his Fig. 8, CLEARLY shows a stable temperature gradient
persisted throughout that run.

Jerry was discussing the effects of a SPATIAL temperature gradient in
air. Your Fig 1, Miller's Fig 8. shows the effect of a temperature
drift with TIME.

Sheese, are you actually as dense as you appear to be?

The figure documents the existence of a spatial temperature
gradient in the room that persists throughout the run.

Start End
N 14.0 N 13.9
E 14.2 E 14.0
S 13.9 S 13.8
W 14.1 W 14.1

At the start of the run, the E and W thermometers are
warmer than the N and S thermometers. At the end of the
run, the E and W thermometers remain warmer than the other
two thermometers. The temperature gradient does shift
slightly.

Your statement, "However, as Miller ventilated his room,
any stable gradients would have been broken up" is false.
The gradients persist.

Miller's simple glass housing was not sealed airtight.
Air could indeed have entered and disturbed Miller's
readings.

Miller's steel apparatus was subject to magnetostriction
effects. Other researchers including Jaseja, Michelson,
etc. noted magnetostriction effects when ferromagnetic
materials were included in their interferometers. For
instance, although Invar spacers constituted only a
minor component of Jaseja et al's apparatus, a periodic
variation in frequency was observed that showed "no
relative variation...associated with orientation of the
earth in space."
Jaseja et al. Phys. Rev. 133, A1221 - A1225 (1964)

Miller's aluminum/brass interferometer, which he
abandoned as completely unusable, proved nothing.
