venient batches during the ga hours of the following days, being

14. No observation of contact times was made, but it is known 
that these times were somewhat before those calculated. As the times 
recorded were reckoned from second contact, it is assumed that this 
occurred May 28, 23 hours 58 minutes 18 seconds Greenwich mean 
time. 
The details of the exposures are given in the following tables:

With the astrographic telescope 12 stars are shown: on a number 
of plates, and seven stars on all but three (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 Doctor 
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.
