The same sounds in the case of my daughter; but from her I heard, up to her tenth month, in spite of all my observation, no other consonants than _g_, _b_, _w_, rarely _l_, and finally _m_-sounds. With my son at the beginning of the seventh month an R-sound appeared--_grr_, _grrr_, plainly associated with _d_ in _dirr dirr_. These sounds were decidedly sounds of discomfort, which expressed dissatisfaction, violent excitement, sleepiness; and they are made even now by the boy at four years of age when, e. g., he is in pain. In the ninth month _dada_ and _b_, _bab-a_, _baeb-ae_ are added. _Agoe_ also is often said, and _oe_ still more often. This _oe_ is already a kind of conscious attempt at speaking, for he uses it when he sees anything new, e. g., the dog Caro, which he observes with eager attention, as he does the cat, uttering aloud meanwhile _oe, oe_. If any one is called, the child calls in a very loud voice, _Oe, oe!_ First imitation. (Gestures have been imitated since the eighth month, and the making of grimaces in the child's presence had to be strictly forbidden.) Understanding for what is said is also present, for when one calls "Caro, Caro," in his hearing, he looks about him as if he were looking for the dog. In the tenth month he often repeats _Pap-ba_, but it has no significance. If "Backe backe kuchen" ("bake cakes," corresponding to our "pat-a-cake") is said to him, he immediately pats his hands as if preparing bread for baking. In the eleventh month _Pap-ba_ is dropped. He now says often _daedaedaedae_, and, when he is dull or excited (_erregt_) or sleepy, _drin, drin_. These _r_-sounds do not occur with my daughter; but since her tenth month she uses _m_-sounds, _maemmae_ when she is sleepy or dull. The boy now stretches out his hand and beckons when he sees any one at a distance. At sight of anything new, he no longer says _oe_, but _aeda_ (twelfth month). He likes to imitate gestures with his arms and mouth; he observes attentively the _movements of the lips of one who is speaking_, sometimes _touching_ at the same time the _mouth of the speaker with his finger_. At ten months the first teeth came. In the eleventh month the child was for the first time taken out into the open air. Now the _g_-sounds again become prominent--_aga_, _ga_, _gugag_. The child begins to creep, but often falls, and while making his toilsome efforts keeps crying out in a very comical manner, _aech, aech, aech!_
