![No. 22. Arrangement of five weights. Place on the table the cubical boxes weighing 3, 6, 9, 12, and 15 g. Say to S: “Here are five little boxes; they look alike, but they don’t weigh the same. I want you to arrange them in order. First put here [at the left] the lightest of all, next the one that is just a little heavier, then the next heavier, then the next heavier, and here [at the rightl the heaviest of all.” This explanation must be tried in several forms, as it is rather difficult to make intel- ligible to many S’s, but the explanation must not suggest that the weights are to be lifted. Note S’s manner of procedure: does he understand the directions, does he test the weights—with one hand or both hands, etc.? Record the order of the weights and rank S in terms of the number of displacements, i.e., the number of changes requisite to bring the weights into their proper order. Mix up the weights and let S try a second, and a third time. Compute the total number of errors for the three trials. The computation of errors may be illustrated as follows: if the order is 3, 6, 9, 15, 12, there are two errors; if the order is 9, 15, 6, 3, 12, there are eight errors; if 3, 9, 6, 15, 12, there are four errors. No. 28. Detection of the missing weight. If S succeeds fairly well in the preceding test, let him close his eyes while E picks out the 9-gram weight. Let *S then examine the four remaining weights, which have, meanwhile, been placed equi- distantly, to see whether he can, by lifting alone, tell which weight has been removed. Repeat the test by the removal of the 6-gram weight, and again by the removal of the 12-gram weight, leaving- four weights on the table in each instance.1 No. 24• Rimes. Making rimes is employed to test extent of vocabulary, general ‘ nimbleness’ of mind, spontaneity, etc. E must first discover whether S knows what a rime is. If he does not, E should try to 1 This procedure is preferable, for comparative purposes, to the removal of a weight by chance as practised by Binet and Simon.](https://iiif.wellcomecollection.org/image/b28083179_0509.jp2/full/800%2C/0/default.jpg)
