[Antionio Morales Perez and thermal etherization]. / Antonio Morales Pérez y la termoeterización.

During the last decades of XIXth century, after a 40-year parenthesis, interest on ether as anesthetic agent is being elicited again in some European countries. In the present paper, we study the personal method of Antonio Morales, the Spanish surgeon. His method, the so-called thermic etherization, is encompassed within the group of techniques that were based on anesthetic vapor heating techniques. We also describe the device designed by Morales and the changes that were introduced later on.
