Sm NOEMAN LOCKYEE AND OTHEES ON THE 
“ Rate of Movement. —It is certain that the bands increased rapidly in speed from 
their first apjoearance to their disappearance at totality, and decreased as rapidly on 
their reap]iearance till they finally ceased. S. B. S. Purkixgtox, who was specially 
told off for this observation, states that they moved too rapidly for him to count 
them. The other two ol)servers at the white sheet agreed. An observer who noticed 
the Ijands at anotlier part of the camp incidentally gave their speed as 4-6 miles 
per hour ; the exact time of this observation is not known accurately ; it was within 
10 minutes before totality. Mr. Mountifield in his note below seemed to have seen 
two sets of shadows ; these were not observed on the sheet at the time of this 
observation ; I was employed elsewhere. 
“ Width of the Bands. —The three observers at the white sheet agreed in estimating 
the hands at ^ inch to 1| inch broad, with one exception (see later). Also that the}" 
varied considerably, and were broadest at the commencement of their appearance and 
when they ceased to appear. 
“ Width of the Spaces. —-The observers agreed that these were very variable, much 
larger, 4 to 6 inches, at the first appearance of the bands, and decreasing to totality 
when they about equalled the hands. At tlie end of totality they were small, as at 
the commencement of totality, and gradually increased in size until the hands were 
actually intermittent. At al)out 1 minute after totality there was a long inter- 
niittency during which a large band, about 2 inches broad, passed by itself in a most 
sti'iking manner ; this was noticed separately by each of the three observers. 
“ General. —The hands were described as ‘ narrow mottled shadows,’ ‘ shadows of 
bands of flocculent wool,’ ‘ ripples of smoke,’ ‘ ripples of water,’ &c. They 
appeared at times to break in two.” 
Note hy Mr. Mountifield.— “ About 5 seconds after third contact light shadows 
were observed of a rippling character, comparing Avith waves, the crests being in a 
N. and S. direction, the transverse velocity about 6 miles an hour to westward. 
Superposed, appeared to be a much fainter series drifting eastward. Distance from 
crest to crest 6 inches to 8 inches. Motion was irreo-ular, as thouo;h an oscillatino- 
motion were acting in conjunction with the onward speed of G miles an hour. 
“ In compliance with a request for further information on one or two points. Dr. 
Nolan states that the bands moved in a direction perpendicular to their lengths, and 
tliat the rods Avere placed in the direction of motion of the bands—pointing in the 
direction towards AA’iiich the hands traA-elled one after the other. In order to remove 
all ■ ambiguity the accompanying sketch (fig. 5) Avas a})pended, in Avhich the arroAv 
indicates the direction of the rod, and the parallel lines shoAv the direction of the 
bands themseDes.” 
The folioAving further description of the bands themseh^es Avas also giA’en 
“ The bands Avere simply narrow bands of shadoAv, parallel to each other, and 
following each other like ripples on AA’ater, and seemed to slightly change their 
direction, as described in the report, as a AAdiole. The shadoAA^s AA-ere observed on the
