to determine the density and the width of the stream at this point in its 
path. We had prepared a circular map of the sky with a radius of about 
32° and a center near y Leonis, and confined our watch to this portion of the 
heavens. The following table exhibits the results of these observations. 
It should be added, however, that these observers were making their 
first meteor observations and that their judgment as to whether a given 
meteor was a Leonid or non-Leonid was probably in many instances pre- 
judiced in favor of the former. Hence I am inclined to believe that about 
eighty per cent. of the meteors observed were Leonids; the remainder be- 
longed to other streams.

On November 15, at 3:02 a. m., a green point of light appeared in the 
sickle at about right ascension 10h and declination 22°. Gradually the 
point of light seemed to spread until it covered an area. In a few seconds
