Captain's log - Stardate 2261.77

Due to the current condition Bones is in, I had Chapel report the testing results directly to myself and Spock. The initial tests have shown an unknown biochemical in his bloodstream that is bound to be the culprit. I've ordered Spock to investigate where the hell this substance came from and who introduced it to my ship.

Since Bones is the best qualified to work on an antidote, Spock has suggested we have him work with the isolated substance without telling him where it was from. Good idea - it will keep Bones busy.
