As in the other cases, all the frogs examined in which the per- 
centage of water was normal, have been included in the records, 
but those with abnormal percentages of water in the central ner- 
vous system have been omitted, hence many of the series contain 
less than twelve records (see table 6), which also gives the funda- 
mental data for this lot.
