With the astrographic telescoj)e 12 stars are shown on a number of plates, and seven 
stars on all but tliree (Nos. 13, 14 and 19). Of the eight plates taken with the 4-inch 
lens, seven show seven stars, but No. 6, which was taken through cloud, does not show 
any. 
The following table of temperatures, communicated by Dr. Morize, and converted 
into the Fahrenheit scale, shows how slight the fall was during totality, probably 
owing to the large amount of cloud in the earlier stages which checked the usual daily 
rise.
