connected with these prominences, though the relationship of some of them to the solar poles was abundantly manifest.
After Totality. Results.
Comparing notes after totality, all observers reported a successful carrying out of the programme. The greatest interest centers in the direct coronal negatives taken with the 135-foot telescope. Mr. Smillie exposed six 30 x 30 plates during totality, with times ranging from one half a second to sixteen seconds, and three others were exposed by him immediately after the third contact.
At this writing only a part of the negatives taken have been developed. Their general quality may be inferred from the examples here given, after due allowance for the great loss suffered by translation onto paper even with the best care.

given here to afford the reader an idea of the general disposition of the coronal light. The upper part is the vertex in the inverted field.
Fig. 2 is a portion of one of the great 15-inch circular images obtained with the 135-foot focus telescope. It was obtained in the great disc in the last exposure during totality of 8 seconds, showing one of the principal prominences then on the sun's dies, with the disposition of the lower filaments near it.
Fig. 3 is a portion of one of the same set of plates, but taken with a 16-second exposure. The part near the sun has, of course, been intentionally over-exposed, in order to better exhibit the remarkable polar streamers, extending here to a distance of about six minutes from the sun, but seen still further in Mr. Child's telescopic drawing (not given.)
Fig. 4 is a view of a small part of the great apparatus on the field, including the terminus of the horizontal tube with its canvas covering, which has been described as like an extended 'A' tent. The photographic room is seen at the end of the tube, and beyond that the tube
