alluded to by Mr. Greg was the periodicity of those bodies, and he 
mentioned more particularly the 19th of May, 29th of November, 13th 
of December, 15th to 19th of February, and 26th of July, as being 
aerolitic epochs, aerolite falls having been recorded on the following 
days :—February 10, 10, 13, 15, 15, 15, 18, 18, 18, 19, 19, 25, 27, 
27; May 9, 10, 17, 17, 17, 18, 19, 19, 20, 22, 26, 26, 27, 28; July 
3, 3, 4, 7, 8, 12, 14, 17, 18, 22, 24, 24, 26, 26, 26, 30; November 5, 
7, 11, 13, 17, 20, 23, 25, 27, 29, 29, 29, 29, 30, 30; December 11, 
remarkable for the periodical displays of luminous meteors, as Novem- 
ber and August 9th to 14th days, Mr. Greg observed that the number 
of aerolites recorded as falling on those days is remarkably small, in- 
d under the average of the year, for out of 155 falls (the day as 
well as month of fall being known), but four have fallen between the 
9th and 14th days of August and November. The aerolitic and (lumin- 
ous) meteoric epochs also would appear to differ, with the exception of 
the 29th of November. 
are resolvable into separate classes ; and in corroboration of this it may 
be mentioned, that, while the number of aerolites whose falls have been 
recorded are about equally divided for the first as for the second half of 
the year, this is very far from being the case with luminous meteors, 
by far the larger numbers of which are observed during the second 
half of the year, viz, from July to December. hile, then, we con- 
consider aerolites as belonging to asteroids, with orbits superior to the 
Earth’s, and partakng of the nature of true though minute planets, the 
majority of luminous meteors may be considered as having characters 
more in common with comets. It has been shown by several astrono- 
mers, as Olmsted, Peirce, Erman, and others, that the majority of pe- 
riodic meteors have orbits inferior to the Earth’s, and their perihelia 
near the planet Mercury. r. Greg concluded, after making some ob- 
servations in favor of the self-luminosity of meteors, by suggesting the 
probability of their having a nature less dense than that of aerolites, 
but denser than that of comets, and that it is not improbable they have 
a fluid or viscid nature. ; ;
