Dr. Morton read a continuation of his paper on Egyptian 

 Ethnography ; which was referred to the Committee already 

 in charge of his former communications under the same title. 



Mr. Walker mentioned, that Professor Kendall and himself 

 had computed anew the orbit of the comet of 1843, but with-
