| We are pushed into thinking that illusions must be departures from quite simple-minded physics, as measured with rulers, protractors, and clocks. |
| In agamids, the homologous muscle also functions to move the tongue forward, assisting the major tongue protractors. |
| Some of the stuff like protractors and compasses I had to design from scratch and I worried about how inaccurate they were. |
| Pen clips, protractors, and jackknives have left hacked shapes to tell people how dull it all was when they sat here. |
| Among the instruments shown are compasses, scales, surveying wheels and chains, theodolites, protractors, and quadrants. |
| Remarkably, the loss of the tongue protractors in chameleons has not affected the external feeding kinematics. |
