The letters of Humphry Davy and his circle, to be published shortly, shed new light on his marriage to Jane Apreece. This paper examines the journeys undertaken by the couple, together and separately, with particular attention to the therapeutic benefits they sought from travel. I argue that their increasingly divergent itineraries reflected a growing understanding that Humphry and Jane had different humoral temperaments or constitutions, leading them to seek different climatic conditions to cure their ailments. While Jane’s temperament was classified as melancholic, requiring her to travel to warmer and sunnier climes during the English winter, Humphry’s was believed to be sanguine, meaning he had to avoid excessive heat along with stimulating food and drink. He relied on classical ideas about individuals’ different humoral constitutions, and the therapies appropriate to them, while measuring atmospheric variables to determine the best places to restore his health. The Davys’ letters reveal the beliefs about bodily differences and atmospheric conditions that shaped their therapeutic travels.

“他们联盟的适应性”：汉弗莱和简·戴维的书信中的旅行和健康

即将出版的汉弗莱·戴维 (Humphry Davy) 及其圈子的来信为他与简·阿普里斯 (Jane Apreece) 的婚姻提供了新的线索。本文研究了这对夫妇一起和单独进行的旅行，特别关注他们从旅行中寻求的治疗益处。我认为，他们日益分歧的行程反映了他们越来越了解汉弗莱和简具有不同的体液气质或体质，导致他们寻求不同的气候条件来治愈他们的疾病。虽然简的性情被归类为忧郁，要求她在英国冬天前往温暖和阳光充足的地方旅行，但汉弗莱的性情被认为是乐观的，这意味着他必须避免过热以及刺激性食物和饮料。他依靠关于个体不同体液构成的经典观点，以及适合他们的疗法，同时测量大气变量以确定恢复健康的最佳位置。戴维斯的信件揭示了塑造他们治疗旅行的关于身体差异和大气条件的信念。
