| My project explores efforts by craniologists to pin down with certainty the extent of the range of variation in human cranial capacity. |
| Mired in the humanistic belief that someone must be pushing the planchette, our unease grows as we cannot pin down the culprit. |
| Musically, it seems fairly straightforward, but it's deceptively hard to pin down. |
| In an effort to pin down good guys and bad guys, or otherwise to dichotomize different approaches, various paired terms have been offered. |
| Now it is back to the linisher to sand the pin down till it is completely flush with the sides of the plane. |
| And if the lepidopteran Scott has proved a difficult biographee to net, the even more fluttery Zelda is yet trickier to cabin and pin down. |
