The Association of
Psychological Studies and Progress, Buenos Aires, Argentinia, was
officially launched on 1 January 1900. The founding group has been
running since 1888 - around a Medium of Spanish Origin, Dona Francisca
Lozano Latorraca (known as "Sister Paca").

All in all in this laboratory the founders were able to
witness the production of different phenomena: Materialization of plants
(flowers), minerals (stones, shells, small objects) and materialized animals, including
the alleged materialization of various live birds in cages securely sealed.


Picture: With the medium "Sister Paca" the first ectoplasmic
formations were photographed in Argentinia: On the knee of the sitter
front left the ectoplasmic production is positioned. The sitters were
claiming the creation was resembling a hand!
In addition levitating tables, levitating chairs as well as
levitating mediums were
witnessed, paraffin wax experiments were done, direct music and direct voices were
heard and the effects of "contacts" between mediums and spirit
in the
ectoplasm, showing faces with different characteristics.

The photograph was obtained by magnesium flash. (Source: Spiritualism , 13,
No. 152-153, January-February 1937, p. 7).
The Laboratories main history in ectoplasmic
materialization, which included ectoplasm human faces, animal in the
ectoplasm, etc. (Marino, 1963)
and many other indefinable ectoplasmic productions were achieved by Dona
Francisca Lozano Latorraca (known as "Sister Paca).
She constituted the
first photographic "evidence" of ectoplasm formation obtained in Buenos Aires by
Argentinian Mediums.

ectoplasm in an experimental session with a second medium called "A.
Montenegro"


Picture: In this stereo image the ectoplasmic structure
seems to connect the both mediums. Such strange ectoplasmic behaviour is
widely spread in ectoplasmic mediumship in South America, especially in
Brazil, where the "interconnecting" ectoplasm can be seen on many photos!
