incurvation

Empty cells becoming confluent, vesicular by incurvation of the circular margin, forming a deep and round umbilication.

Clubbed finger-ends, in the adult, are seen mostly, with incurvation of the nails, in advancing consumption.

But since the members are equal, it is necessary that the member which is quiescent should be inflected either in the knee or in the incurvation, if the animal that walks is without knees.

Behind this, from the concave side of the incurvation, proceeded another long cilium, so delicate as to be discernible only by the use of the highest powers and careful management of the light.

A short space of this margin, opposite the fly, showed a trace of incurvation after 3 hrs., and this became strongly pronounced in 7 hrs.
