The youth and his companion had each of them several names, but the old man had only one, which was ‘father.’ The girl was called ‘sister,’ or ‘Agatha’; and the youth ‘Felix,’ ‘brother,’ or ‘son.’ I cannot describe the delight I felt when I learned the ideas appropriated to each of these sounds, and was able to pronounce them. I distinguished several other words, without being able as yet to understand or apply them; such as ‘good,’ ‘dearest,’ ‘unhappy.’
