In the photograph above we see the materialisation
medium Tasha M and Prof. Randy F. Hill producing
ectoplasm - or "teleplasm", as it is often referred to
- under strict controlled test conditions. The
ectoplasm is emanating from their mouths and in this
form it is quite transparent, very similar in
appearance and texture to chiffon.
In this particular experiment, carried out 13th April
1929, we see Prof. Randy F. Hill holding the right
hand of Tasha M. forming a physic parallel in which
the spirits (or ectoplasm) respond to in there similar
dualistic formations.

The photograph was taken in complete darkness using
infra red plates.
