N. R. Leonard—lowa County Meteor. 359 
the observers thought that the meteor attained its maximum 
brightness when about due west of that place. Some of the 
students who were familiar with the color of the flames of different 
substances with which they had experimented in the Chemical 
Laboratory called out at the time that the color of the meteor 
showed iron and copper. 
In computing the path pursued by the meteor I have relied 
almost entirely upon observations which could be verified 
afterward, by reason of its having passed near to, or behind 
some recognized point on a building or other object whose 
altitude and bearing from the station of the observer have since 
been ascertained by instrumental measurement. 
_ In giving the data I will denote the location of each observer 
by mentioning the section, township, and range numbers, 
which, as our lands are laid out on the rectangular method, 
will be quite definite. 
‘de following is a list of observations upon which I have 
relied, 
1. At Amana (northwest corner of 26-81-9). Mr. F. Chris- 
ten first saw the meteor when at an altitude of 10 or 11 degrees 
and at a bearing of S. 19° W. Soon after he saw it passing 
near the top of a chimney whose bearing and altitude were 
respectively S. 26° W., and 174° and finally saw it separate and 
disappear at an altitude of 29° bearing S. 65° W. 
2, At Mt. Pleasant (4-71-6), there is not a perfect agree- 
ment as to the altitude of the meteor when due west of that 
place. Some thought that it passed very near the moon, others 
To 
of about N. 60° W., at between 10° and 12°. 
Another observer gave the altitude when near the same 
poe at 10° 30’. Both observers saw the meteor disappear 
orcaks B. rt, of Washington, Iowa (17-75-17), 
thought that it passed 10° or 15° west of the moon. Ce 
6. Prof. J. Macomber of the Iowa State Agricultural 
College (4-83-24), first saw the meteor when at an altitude of 
7 or 7° 30’ and bearing S. 55° E. This observation is almost 
exactly accordant with one taken independently at the same
