In the head, a): "There is a reference to this specimen in Newton's letters" - written by me, Estela Guedes
Ending: "Today I asked Moller for the information that you asked me. He brought the snake from São Tomé. He caught it at the ROÇA MABUDO [Moller's calligraphy]. He kept it at home with other snakes, thinking it was a duplicatum. Finally, he decided to send all the duplicata to Bedriaga and among them was that snake."
