He gave vent to emphatic protests of incredulity when his guess of 'about 200' was met by the actual number of 2,170. And we ourselves have found several times that, after following a child about all day with pad and pencil and taking down all his talk for a waking day till we were almost exhausted, when we then tried to make an estimate of the words used we have only come to within a quarter to a half of the right number. This illusive underestimation of a child's vocabulary is so universal that it can only be corrected by cataloguing, indexing and actually counting the words thus recorded for a whole day. In the following table are given the different words and the total number of words used by two of our children on the day they were each two and a half years old:

It is interesting to find from the complete tables that of the 751
