Heart malformation, such as PTA, DORV, VSD and aortic arch malformation, were detected when neural crest were taken out before they migrated into 3, 4, 6 pharyngeal gland. Interestingly, the types of malformation were related with the length of neural crest destroyed; PTA was detected if the length exceeds two somites, while DORV would be detected if the length less than two somites. These results indicate that CNCCs are very important to the conotruncal development.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
