History: VS discoveries Paul Camilleri
I noticed (by chance) the following e-mails, which I received from
Paul Camilleri on 1992 December 29. I hope this historical document is
still of interest.

very diffucult to resove on the small scale of the 85mm lens.

Dear Paul,
Many of PC variables have been identified with IRAS-PSC objects,
supporting the Mira classification.
For full description, please see the Catalog.
Will it be possible to distribute your list to our observers for
future monitoring? (although many are located too south in Japan)
