332 On the Meteors of 13th November, 1833. 
the course of the meteors, at 5 o’clock, would have lain far N. of 
W. and the radiant would have wheeled round rapidly towards the 
south, as morning approached. For Capt. Parker’s observation see 
his statement (p. 399 vol. xxv) of which more will be said hereafter. 
From the above mentioned sources of information, and upon such 
authorities the table above was constructed ; each computation being 
made upon its own independent data, without the slightest effort at ac- 
commodation; and, where there is supposed to be an uncertainty 
amounting to several degrees in any result, that uncertainty is indicated 
by the double sign + attached to that particular result. Although itis 
reasonable to suppose that the correspondence of the results derived 
from the less definite observations with those results which are best 
settled may be in part accidental, yet, by comparing the second and 
third columns of the table it will be strikingly evident, not only that 
there is a progressive increase of north declination in southern lati- 
tudes, but that the differences of declination compared with the dif- 
ferences of latitude are strikingly correspondent. ‘To exhibit this 
correspondence (whatever be its cause) the third column was calcu- 
lated, by dividing the interval between each successive declination and 
the declination at the head of the column by the corresponding dif- 
ference between each successive latitude and the latitude at the head 
of the coluran. Considering that the table includes every observation 
that is known, and that is sufficiently definite to afford data fora spe- 
cific location and that the observations were necessarily loose in their 
nature, being made by the eye alone,—the degree of proportionality 
which the fourth column exhibits must go far to satisfy the mind, that 
there was, in fact, a more northern declination in the more southern 
latitudes. 
This change of declination is in the proper direction to be the 
effect of parallax, and might be made the basis for calculation res- 
pecting the distance of some imagined body or place from which the 
meteors took their departure, were it not that the supposition of a 
parallax in declination is totally annulled by the entire absence of a 
corresponding parallax in right ascension. ‘This absence is so stri- 
king, as one may see by reference to the table, that the right ascen- 
sion at New Haven and at Worthington—places more than 10° of 
longitude apart in the latitude of 40°, and more than five hundred _ 
miles asunder in absolute distance—was the same at the same 
moment of absolute time,—the same, for example, at 5 o’clock ‘of 
Worthington time, and 5h. 40m. of New Haventime. Also by com-
