MAY I call attention to the fact that the line at 4026.5, now recognised as belonging to the spectrum of helium, and conspicuous in the Orion stars, is also prominent in the spectrum of the solar chromosphere. Although not given in the catalogue of chromosphere lines (which dates from 1872), it was observed and published as long ago as 1883 (Am. Jour. Sci. and Art., November 1883), in connection with another line at 4092, seen at the same time. Since then the 4026 line has been observed repeatedly, and might be given a place in the catalogue with a relative frequency of about 15, and a brightness of 3 or 4. Like the other helium lines it has no dark analogue in the ordinary solar spectrum. The 4092 line falls upon a strong double line shown upon Rowland's map, but I am not sure to which of the two components it belongs; it is faint, and seldom seen.
