Superstition in Teratology.

Superstition in the pigeon.

In vitro teratology.

The purpose of this conference was to reevaluate the need for and use of in vitro teratology assays; to examine the validation process for in vitro tests; and to discuss progress in the validation of in vitro teratology screens. Participants enthusiastically supported further development of short-term in vivo and in vitro systems both as prescreens for developmental toxicity and as experimental...

The code specified an “appeal by surviving in the river” as a way of deciding whether an accusation was true, so it seems to have relied on the superstition that the guilty are more likely to drown than the inn...

The first volume in this series does range topically in including reviews on aspects of cytogenetic, pharmacological, radiobiological, and immunological problems. If a field such as teratology is to be reviewed, one cannot expect a high degree of correspo...
