Dr. Engelmann presented from his brother, Henry Engel- 

 mann, a series of rocks and fossils collected by him while 

 acting as Geologist of the Expedition under Lieut. Bryan, IT. 

 S. Top. Eng. for the survey of a wagon route frcm Kansas to 

 Utah. 



Dr. Engelmann gave an account of the unusually \iolent storm which 

 prevailed yesterday, May 5th, accompanied by a fall of the barometer, 

 such as he had, with one exception, not observed in the course of 

 twenty- four years.* The lowest and most extraordinary stage of the 

 barometer he had noticed here was 28.516 inches, at 4i P. M., March 

 28th, 1859, during a violent thund>>rsform, with hard rain and north-west 

 wind ; yesterday the lowest was 28.611 inches, nearly 0.10 inch higher. 



During the l=t and 2nd of the month the barometer was high, with 

 easterly winds and a cle.r sky. On the evening of the 2d it be^an to 

 fall; vacillated on the 3d during storms fiom the west and north ; fell 

 still more with easterly winds and a clouded sky on the 4th, till in the 

 morning of the 5th, during a thunderstorm from 6-8 o'clock A. M., with 

 high eastern winds and a fall of 0.40 inches of rain, it fell at 7 A. M. 

 to 28.774, and continued to fall till 2 P. M., during a most violent storm, 

 approaching a hurricane, from the south-west, as the following table 

 shows :
