On p. 25, Figure It Out 2.3, the last paragraph (about Joseph Fraunhofer) belongs at the end of the caption of Figure 2-4 on p. 26.
The paragraph says: “Note that Fraunhofer labelled lines with letters from A through H and then used I for the end of the spectrum.  Though most scientists don’t realize it, the K line of ionized calcium so often referred to in astronomy as a Fraunhofer line wasn’t given its notation until the mid-nineteenth century.”
