[ATM] Speculum mirrors and James Nasmyth

[James P Crombie <jpcrombie@pei.eastlink.ca>]

I ran across an autobiography of James Nasmyth this afternoon.  A lot of 
interesting history there.  Include a chapter or two on his astronomical 
works and telescope building efforts.
For those in the group that were expeirimenting with cast mirrors there 
is a short dissertation on the casting of such at
