I noticed that the word “spectography” gets a red-squiggly-underline, suggesting it isn’t properly spelled. Well, okay… But “spectrography” also is marked as wrong… I’m pretty sure one of these is right, but I wouldn’t bet my left leg on which…
Does a mod or admin control the auxiliary (hey, I spelled it right!) word list? Can we request certain words to be added? Does it matter a whole lot? Is bimetallism an answer to the cross of gold?
I’m pretty sure “spectrography” (your second try) is the correct one. Chrome doesn’t seem to like either choice. Must be an unusual enough word to not be in the built-in dictionary.
