finest and most interesting objects which the heavens afford. Uranus is just 
entering the constellation Virgo. It is now a morning star, and too near the Sun 
to be observed, though it might probably be seen with a telescope toward the end 
of the month, especially as it is very near a third magnitude star. Beta in Virgo. 
Neptune occupies a blank region in Taurus, near 8° southwest of Pleiades; R. 
A. 3 h. 15 min.; declination 16° 12' north on the ist. It changes place but 
little during the month. The brightness of this planet is about that of an eighth 
magnitude star, and hence requires a pretty fair little telescope to show it. 
CORRECTION. 
Editor Review : — I have noticed two errors in my Table of Eclipses (Re- 
view, No. 4, Vol. VII,) which it might be well to publish with their corrections. 
(They are my own, not the printer's). The eclipse of 1881, November, should 
read November 21st, 7 A. M., instead of " November 20th, midnight," as I put 
it; and 1882, "May i6th," should read May 17th.

PRACTICAL HINTS REGARDING TORNADOES. 
JOHN D. PARKER, U. S. A, 
The following hints regarding tornadoes are given in the belief that many 
people are killed every year who could save their lives by a little practical knowl- 
edge of the movements of these destructive storms. 
The tornado season is embraced between the ist of April and the ist of Sep- 
tember, but in the latitude of Kansas City most tornadoes occur in the months of 
May and June. As we go north or south of this latitude they are proportionally 
earlier or later, and early or late seasons vary the time of their occurrence cor- 
respondingly. 
Tornadoes occur in the afternoon, generally between two o'clock and even- 
ing, four o'clock being called the tornado hour. 
Tornadoes move from southwest to northeast, generally east about twenty de 
grees north, and their linear movement is ordinarily from thirty to forty miles an 
hour. 
Tornadoes occur on sultry days, or when the temperature is very high and 
the air is thoroughly saturated with moisture. 
Tornadoes occur when the electrical conditions are high, or when the air is 
highly charged with electricity.
