themselves, but of the intention put into them by the speaker. I should be glad to know if the experience of others tends to confirm this theory, which I do not remember to have seen suggested before. A. EUBULE-EVANS. [_Aug. 18, 1883._] I beg to contribute another anecdote on the subject of how our meaning is conveyed to animals. When I was in Norway with my husband, a dog belonging to the people of the house went with us in all our walks. One day a strange dog joined us, and seemed to wish to get up a fight with our dog, Fechter, who for protection kept almost under our feet; my husband said several times, "Go on, Fechter," in English, which he immediately did, but soon came back again. At last we succeeded in driving the strange dog away, but he soon returned. Then my husband said without any alteration of tone or gesture that I was aware of, "Drive that dog away, Fechter." He immediately rushed at him, and we saw no more of our troubler. I have long thought that dogs do understand, not "the precise sounds themselves, but the intention put into them by the speaker." AN OBSERVER OF ANIMALS. ANIMAL INTELLIGENCE. [_Aug. 18, 1883._] Perhaps I should have said the "Intelligence of Animals," but my meaning, in relation to the interesting correspondence in your columns, is no doubt clear. The whole question seems to me to lie in the proverbial nutshell, and to be solvable by the proverbial common sense. Dogs' hearing is undoubtedly very keen and accurate, and even subtle; and dogs have also the power of putting this and that together in a marvellously shrewd and almost rational fashion. They cannot understand sentences, but they get hold of words, _i.e._, sounds, and keep them pigeon-holed in their memory. I might as well argue moral principle from the fact that my dog Karl, like scores of other dogs, will hold a piece of biscuit on his nose so long as I say "trust," and will when I say "paid for" gaily toss his head and catch the biscuit in his honest mouth, as argue that because he finds eleven tennis-balls among the shrubs in five minutes, when I say, "We can't find them at all, Karl; do go and find them, good dog, will you? Find the balls, old fellow"--therefore he understands my sentence. He simply grasps the words "find" and "balls," sees the game at a standstill, and reasons out our needs and his responsibilities, quickened by the expectation of pattings on the head, pettings, and pieces of biscuit. It is remarkable that if I try to delude him by uttering "base coin" in the shape of words just like the real words, as, for example, if I say "Jacob" instead of "paid for," he makes no mistake, but refuses the morsel, however delicate, till it _is_ "paid for."
