How many photographs
were there in Piazzi Smyth's pyramid collection. Slide no.
31 (above) is the highest number I have seen for any of his slides.
Five more of Piazzi
Smyth's slides in apparently the same series as above were sold on the eBay Auction Site
today [29 May 2003] for a total cost of £42. The slides each measured 3.25
ins x 3.25 ins.
mounting was very similar to the one illustrated above. Most were hand-coloured. The numbers
on four of the slides were 12, 15, 17 and 22. The fifth
slide was not numbered. So No 31 (illustrated above is still
the highest numbered of this series that I have seen).
