CHOP-STICKS 484 CHRESTIEN DE TBOYES a pianist. In 1835 he visited Germany, Leipsic, and other cities, and in the same year made a trip to England, which, while it lasted only 11 days, was sufficient to develop the germs of con- sumption. In 1837 he met George Sand who was then living separately from her husband. Chopin was at the time ill and she undertook to nurse him, and, in the years following, they lived in Paris, where they were both conspicuous in social and musical circles. A break in their relations came in 1847 as the result of a quarrel. Chopin continued to give concerts in spite of the fact that he continually grew weaker physically. He visited London again in 1848. He died in 1848,. Chopin is considered to be the creator'of a new style of writing for the piano, and his achievements as a com- poser entitle him to a foremost place among the masters of music.
