2. The filiform P. Ouei, a threadlike pulsation.
3. The moderate P. Ouan, slow and languid.
4. The sharp P. Soe, producing the sensation of a cutting or sawing instrument.
5. The slow P. Tehis, when the pulsations follow each other with languid intervals.
6. The sinking P. Fou, when the pulse, although pressed hard, sinks under the finger.
7. The soft P. Sin, which feels like a drop of water one might press upon.
8. The weak P. Yo, which yields the sensation of feeling like a worn-out texture, and ceases to be observed when pressed upon for any time.
To these are added nine other varieties, called Tao.
1. The long P. Tehang, full, smooth—feeling like a full tube.
2. The short P. Toan, presenting a pointed surface, that seems indivisible.
