METEOKITES IN INDIA. 



The details have recently been received of a very remark- 

 able fall of meteoric stones that took place on the 23d of 

 September, 1873, in India. The largest pieces and the great- 

 est number fell near the village of Kahirpur, in latitude 

 29 56' K, longitude 72 12' E. Five stones are mentioned 

 as having fallen at this place, but others appear to have 

 been obtained. At a number of other places stones also 

 fell, and the whole district over which the fall seems to have 

 spread has a length of sixteen miles in a southeast and north- 

 west direction, and a breadth of about three miles. Many 

 of the stones were found imbedded in the earth at a depth 

 of about eighteen inches. The largest three weighed ten 

 pounds, and were very irregular in shape, and all broken. 

 As to the composition of these aerolites, it is of the usual 

 steel-gray color and dense crystalline texture. The specific 

 gravity of one of the pieces is given at 3.66. The appear- 

 ance of the meteor was exceedingly brilliant, and its disap- 

 pearance was followed, after an interval of about three and 

 a half minutes, by a loud report, whose long reverberation 

 died away like distant thunder. Journal of the Asiatic So-

ANCIENT EGYPTIAN ASTRONOMICAL OBSERVATIONS. 



Renouf has communicated to the Society of Biblical Archae- 

 ology the result of his study of the astronomical calendar 

 which was discovered in 1829 by Champollion near Thebes, 

 and which was supposed by him to present a table of the 

 constellations and their influences for all the hours of each 

 month in the year. This calendar, which lias for fifty years 

 formed the subject of numerous publications and specula- 

 tions, is now interpreted in a very different manner by Re- 

 nouf, who decides that it is a record of the position of the 

 stars in the sky at certain times in the night. It is, in fact, 

 a table of observations, and not of astronomical calculations. 

 Once in the course of every fifteen nights the observer ap-
