This sonnet stands independent of the rest, and was written as a first attempt at a sonnet. (Most sonnets are written in sequence, more about that later.) The rhyming pattern is abab bcbc cdcd ee. I am not aware of anyone having used this rhyming scheme before (it’s not super-original, I’m sure someone has).

The title, Argon in Air, refers to the relative rarity of argon (a noble gas) in air. Argon is present in air at approximately 0.9%, which to my surprise when I actually checked the facts, is actually a higher concentration than carbon dioxide at 0.03%. This may go to show that what the protagonist in the poem is looking for (luckily for him) is not as impossible to find as he thinks it is!
