their base. The}’ never again left this position. No. Two made 
the same record. The pappus disk is also concave until it be- 
comes convexed 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, 1 1 were marked “ rainy ” 
and 8 “ cold.” 
PREHISTORIC ANTHROPOLOGY. 
[abstract.] 
Address of the Retiring President, Mr. Mills, Delivered at the November 
Meeting of the Biological Club, at Orton Hall. 
Mr. 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. Mills 
was able to discover at the Baum village site along Paint creek, 
and the Gartner Mound 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 Museum, and there identified and
