ON THE TOTAL SOLAR ECTAPSE OF AUGUST 29, 1880, 
295 
believed every possil)le pains liad been taken in its regulation. It was only by a 
lucky alteration in tbe balance at the last moment that it was induced to go on at all. 
Captain Archer had kindly sent us two sailors to render help during totality, viz., 
Samuel Browett, signalman, and Henry Steele, petty officer. One of these two 
was placed between the two huts to call out the time at intervals of half a minute 
while the other was to assist Captain Darwin in the inahipulation of his instrument. 
They both did what was required of them admirably. 
During totality Captain Darwin required no other assistance, as his programme 
was not heavy ; but with Dr. Schuster, whose whole observations were iricluded in 
that time, the case was different. He gratefully accepted therefore the help offered 
to him by Dr. P. F. McLeod, the rifficer of health in Grenada, and by Mr. Murray, 
who accompanied the expedition as naturalist. 
Captain Maling had undertaken to make a drawing of the outer parts of the 
corona. According to a suggestion of Mr. Lockyer’s, a disc had been prepared 
6f inches in diameter. When placed at tlm proper distance the Moon and the inner 
parts of the corona could be screened off by means of this disc. It was placed on a 
wooden support at the top of an incline which ran down from the observatorv to the 
sea shore. A post w'as driven into the ground some distance away from the disc. 
The observer was to look through a small hole in the post. This arrangement, 
however, wants very careful adjustment, and we had not much time to spare, as the 
principal objects of the expedition monopolised nearly all our attention. Whether 
from want of adjustment or from other causes, we cannot now decide. Captain 
Maling’s drawing includes the wdiole o'f the corona down to the prominences. 
Captain Maling’s statement is included in this report.
