1. The August Meteors in 1867. 
The August meteoric shower, in 1867, was more irregular in the time and 
place of its appearance, as remarked by M. Quetelet, than it appears to have 
been observed in any previous year. A great scarcity of meteors about mid- 
night on the night of the 10th was observed at many places, and especially 
in ‘Ttaly—at Milan by Prof. Schiaparelli, at Palermo by Prof. Cacciatore, and 
at Varallo, in Piedmont, by Prof. Calderini. The following are the numbers 
counted by the latter observer, watching alone, the sky being perfectly clear, 
and the moon uniformly bright throughout the time of the observations :—

Two great maxima, however, appear to have occurred—one on the morning 
of the 11th, and another on the morning of the 12th. The first maximum is 
recorded by Prof. Ragona in the following Table of observations at Modena, 
continued to a late hour on the morning of the 11th :—

A great abundance of meteors towards three o’clock a.m., on both morn- 
ings of the 11th and 12th, was also noted by Father Parnisetti, Prof. Porrati, 
and their assistants at Alessandria, a group of ten or twelve meteors, on the 
morning of the 12th, sometimes appearing together in one minute. The 
sky was perfectly clear throughout the observations.
