useful data for a definitive picture of the corona independent of 
the photographs, and which may be a real contribution to our 
knowledge of the corona of 1901.

made on all sorts of plates with all sorts of cameras, 15 appear 
to be practically useless. The quality of the others is given in the 
following table, where
