He knows the songs and asks of his own accord for _Kucku Esaal_, _Kater putz_, _Kucku tralla_, but commonly hears only the first stanza, and then wants a different song. Lately, however, he listened very earnestly to the three stanzas of "Moepschen," and when I asked "What now?" he answered _Noch Mops_ (more Mops). Playing with his puppets, he hummed to himself, _tu, tu, errsen, tu tu errsen_. I guessed that it was "Du, du liegst mir im Herzen," which he had on the previous day wanted to hear often and had tried to repeat. _20th Month._--Now for the first time _ja_ is used for affirmation, chiefly in the form _ja wohl_ (yes, indeed, certainly), which he retains. "Do you want this?" _Ja wohl._ Being asked "Whose feet are these?" he answers correctly, _Mine_; but no personal pronouns appear yet. He often retains a new and difficult word that he has heard only once, e. g., "Chocolade." To my question, after his grandfather had gone away, "Where is Grandpapa now?" he answers sorrowfully, _verloren_ (lost). (Cf. p. 145.) In his plays he imitates the doings and sayings of adults, puts a kerchief about his head and says, _Adolph go stable, give oats_. Not long ago, as he said good-night to us, he went also to his image in the glass and kissed it repeatedly, saying, _Adolph, good-night!_ _24th Month._--He knows a good many flowers, their names and colors; calls pansies "the dark flowers." He also caught the air and rhythm of certain songs, e. g., _Kommt a Vogel angeflogen, Du, du, liegst mir im Herzen, machst mir viel Serzen_, and used to sing to himself continually when he was on a walk. Now that he is four years old, on the contrary, he hardly ever sings. _25th Month._--Beetles have a great interest for him. He brings a dead beetle into the parlor, and cries, "Run now!" His astonishment is great that the creature does not run. If he sees something disagreeable (e. g., he saw the other day an organ-grinder with a monkey), he covers his face with his hands weeping aloud and crying, _Monkey go away_. So, too, when he sees strangers. The Latin names of flowers and insects are easily retained by him. They are not taught him, he simply hears them daily. _26th and 27th Months._--Of his childish language he has retained only the term _mammut_, for berries. Milk, which he used to call _mima_, is now called _milch_ (cf., pp. 140, 157).
