Certain charts and reports of meteorological observations were 

 received from Mr. E. H. Singleton, U. S. Signal Observer, at St. 

 Louis, with an offer to continue them monthly. They were di- 

 rected to be filed for preservation. 



Mr. C. V. Riley on behalf of Mr. James Harkness presented 

 for the museum a probable Indian skull found at a depth of fifteen 

 feet in one of the mounds near East St. Louis. The skull 

 was somewhat peculiar in form, being decidedly dolichocephalic 

 in type, and very low in the frontal and superior regions, thick, 

 and heavy. The exact position where found and the accompany- 

 ing circumstances were not communicated. 



Mr. Riley exhibited specimens of Acridium americanum^ the 

 whole inner soft parts of which had been eaten away by the small 

 I'ed ant (yMyrnilca minuta)^ leaving nothing but the outside skin 

 or shell. Just as ants will neatly clean the flesh from the internal 

 vertebrate skeleton, so they had done in this instance from the 

 external invertebrate skeleton. 



Mr. Enno Sander presented from Dr. H.Johnson of Jackson- 

 ville, Ills., a piece of shale showing impressions, which were re- 

 cognized by Dr. Engelmann as impressions of some plant.

 name of the Academy of Science, signed by him as Treasurer of said Aca- 

 demy, as needed for the payment of its debts or expenses."
