OBSERVATIONS OF LUMINOUS METEORS. 345 
the Astronomical Society is pointed out in Herr von‘ Konkoly’s determination 
of the radiant-point. As extracted from Dr. Heis’s collection (and not from 
Signor Denza’s (D) as stated in the list) the N. declination of the radiant- 
point observed by Herr von Konkoly was 45°. Signor Denza’s description, 
translated from that of Prof. von Littrow in the ‘ Wiener Zeitung,’ gives. 
55° as the N. declination. In a letter since received from Herr von Konkoly 
he observes that his first accounts of the shower contained an eye-estimation 
of the position of the radiant-point, and that on afterwards pointing an 
equatorial telescope towards the exactly selected spot, an accurate position of 
the radiant-point was obtained. This was at a place in R.A. 1" 45" (+5™), 
Decl. +45° (+1°), or about in R.A. 262, N. Decl. 45°, a position agreeing 
very closely with the probable true centre of the meteoric shower. 
The following few observations of the radiant-point appear to have been 
omitted from the above-mentioned list :—

In another portion of his letter attention is directed by Herr von Konkoly 
to typographic errors in the accounts contained in the ‘Monthly Notices’ 
of the Astronomical Society (vol. xxiii. p. 575, and vol. xxiv. p. 82) of 
spectroscopic observations of a large meteor’s streak and of the August 
shooting-stars made at his recently erected and equipped observatory at 
Ogyalla in Hungary. With regard to the August shooting-stars, those 
only which were observed by Herr von Konkoly himself were examined 
with the meteor-spectroscope on the nights of July 25th and 26th, 1873; 
while the large number of shooting-stars recorded by his assistant on these 
and the following nights of the August period were noted with Littrow’s 
meteoroscope for fixing the positions with the naked eye. The spectra of 
three meteors seen with the meteor-spectroscope by Herr von Konkoly nearly 
resembled each other, that of the nucleus being continuous and the yellow 
sodium band being visible in the streaks. In the spectrum of the third 
meteor green predominated in the nucleus, and the green band of magne- 
sium, in addition to that of sodium, was visible in the streak. 
The next application of the meteor-spectroscope, described by Herr von 
Konkoly, was made on the streak of a large meteor on the night of the 
13th of October, 1873. The streak was about 15 minutes broad when first 
observed, and traces of it were still visible in a comet-finder 25 minutes 
after the meteor had disappeared. The appearance of this streak in 
Browning’s meteor-spectroscope showed very finely the bands of sodium and 
magnesium. Proceeding to direct the telescope armed with a star-spectro-
