Spontaneous Languages.—We noticed, several months ago, a deeply interesting study of the spontaneous development of language in children, by the Hon. Horatio Hale. The same phenomenon—tantamount to the creation of an original tongue—has been observed by other persons; among them, Miss Watson, of Boston; Dr. E. R. Hun, of Albany; Archdeacon Farrar (in the case of Indian children left by themselves for weeks together in Canadian villages); and by M. Taine, in his work De l'Intelligence. Mr. W. J. Stillman has recently communicated to Nature observations made by him upon his son several years ago, when he was under the care of an Italian nurse. As the child's utterances took shape it was found that he repeated certain sounds with a definite meaning, and soon coined a small vocabulary for himself, comprising words for bread, water, milk, etc. The first word distinguished was chumbhoo, for water. Then in a few weeks he began to couple the Italian words with his, and said chumboo-aqua. Little by little he dropped his own words and began speaking only Italian. Recently, when on a visit to Crete, Mr. Stillman met a boy who had formed for himself a similar language, with the same word for water as his own son had invented. Mrs. Agnes Crane cites in a later number of Nature the case of a nephew of Dr. George Gablentz, a well-known Sinologist, who, before he learned his mother-tongue, called things by names of his own invention. The constant elements were the consonants, while the vowels were varied and employed as they were deeper or higher to denote greatness or smallness. The root for round
