their base. They never again left this position. No. Two made 

 the same record. The pappus disk is also concave until it be- 

 comes con vexed to help open the pappus head. While it is 

 concave the pappus hairs stand erect and parallel ; but by becom- 

 ing convex the disk forces the hairs to radiate like the stays of 

 an open umbrella. 



In No. One, the head faced the sun from morning until noon 

 while in bloom ; No. Two did the same. But this seems to be a 

 rule to which there are exceptions. 



After the seed is scattered the scapes soon wilted and fell to 

 the ground. 



In No. One the full length of the scape was twelve inches ; in 

 No. Two, nineteen inches. The grass was taller around No. 

 Two. In tall grass or in a pile of rails, the scape may reach a 

 yard in length and stand erect most of the time, while on lawns 

 that are frequently mowed they are usually short. 



No. One grew in the back yard, on the northwest side of its 

 bunch, and when the scape flexed it always bent in that direction. 

 No. Two grew near the same place, on the south side of its bunch, 

 and when the .scape bent it was always in that direction. Of the 

 76 records made of No. One, 28 were marked "rainy" and 18 

 " cold " ; in the 68 made for No. Two, 11 were marked " rainy " 

 and 8 "cold." 



PREHISTORIC ANTHROPOLOGY. 



[aestiiact.] 



Address of the Retiring President, Mr. Mills. Delivered at the November 

 Meeting of the Biological Club, at Orton Hall. 



]\Ir. Mills gave a review of prehistoric Anthropology, which is 

 accredited to the scientists of Denmark, who had stamped the 

 meaning upon the word Anthropology, designating it as a science 

 well recognized and as definite as the science of Botany, Chemistry, 

 Zoology or Geology. He also reviewed the obstacles encountered 

 by the investigators in the study of prehistoric Anthropology. A 

 great many of the discoveries were due to the persistence of Pro- 

 fessor Steenstrup, one of the Commissioners of Denmark, who 

 first discovered that prehistoric man had the domesticated dog by 

 finding bones that had the appearance of being gnawed. By 

 applying these observations to the village sites of Ohio, Mr. INIills 

 was able to discover at the Baum village site along Paint creek, 

 and the Gartner Moiuid along the Scioto, a number of bones that 

 had the appearance of being gnawed, and this led to the discovery 

 of the domesticated dog at this place. These bones were after- 

 ward sent to the National Mu.seum, and there identified and
