An opportunity for a tremendous boost to my researches -- I've discovered a colleague on the continent! I'm thrilled, and yet, somewhat envious. He's a world traveller, and gets to eat lizards. He also began his researches before I did, and consequently has beaten me to several major discoveries. For example, he lives with two of them, too, but has successfully categorized them into two classes by the tonality of their vocalizations! Amazing! I will have to redouble my efforts. Look for a treatise soon on the theory and practice of knocking things onto the floor as a means of getting their attention.
