Wilderness and health in the nineteenth century

During the latter part of the nineteenth century a form of medical treatment often called a “wilderness cure” enjoyed considerable popularity in the United States, especially in California. This procedure involved little more than an open-air sojourn in wild country, usually wooded uplands. It was based on the belief that wild, timbered uplands exerted curative influences on sick persons, especially consumptives. The cure's effectiveness was supposed to derive from influences of climate, vegetation, and style of living as well as spiritual influences related to aesthetics. Wilderness therapy fell into desuetude in the twentieth century as the realization spread that the wilderness environment was of little value in combating microbial and other agents of disease. In its heyday, however, the wilderness treatment attracted much support and was undertaken by a great many invalids. It seems highly likely that the perception of the wilderness as a source of health softened pre-existing negative attitudes to wild landscapes in America.     

Brain physiology and the mind in the nineteenth century

This article explores the integration of research and theory in nineteenth-century neurophysiology. Four generalities combine to explain their integration. They are the core beliefs of the neurologists, the pervasive habit of perceiving mind when observing behavior, the criteria for the existence of mind, and mind as an efficient cause. These generalities help explain specific choices made by certain researchers to work within the traditional model of the nervous system, to reject materialism, and to find intelligence and voluntary behaviors in physiological systems.     

自由主义与加拿大宪政改革

在19世纪上半期加拿大建立责任政府的过程中,自由主义观念起了重要的促进作用.这不仅表现在自由主义思想对加拿大殖民地人政治意识觉醒的推动上,更表现在英国社会与政坛对英帝国与移民殖民地关系认识的改变上.由于美国独立的教训,维护帝国统一和防止殖民地与母国分离,曾是英国人心中一个不解的结.因此,旧观念支配下的英国统治集团,几乎一致地拒绝了达勒姆关于授予殖民地责任政府的建议.随着英国自身现代政党制度的确立和自由贸易的实现,新的自由主义帝国观开始形成,并直接推动了加拿大的宪政改革.     

Spirometry, measurement, and race in the nineteenth century

Race correction is a common practice in contemporary pulmonary medicine that involves mathematical adjustment of lung capacity measurements in populations designated as "black" using standards derived largely from populations designated as "white." This article traces the history of the racialization and gendering of spirometry through an examination of the ideas and practices related to lung capacity measurements that circulated between Britain and the United States in the nineteenth century. Lung capacity was first conceptualized as a discrete entity of potential use in the diagnosis of pulmonary disease and monitoring of the vitality of the armed forces and other public servants in spirometric studies conducted in mid-nineteenth-century Britain. The spirometer was then imported to the United States and used to measure the capacity of the lungs in a large study of black and white soldiers in the Union Army sponsored by the U.S. Sanitary Commission at the end of the Civil War. Despite contrary findings and contestation by leading black intellectuals, the notion of mean differences between racial groups in the capacity of the lungs became deeply entrenched in the popular and scientific imagination in the nineteenth century, leaving unexamined both the racial categories deployed to organize data and the conditions of life that shape lung function.     

The weight of nineteenth century Mexicans in the Western United States

When traditional methods for measuring economic welfare are scarce or unreliable, heights and BMIs are now well-accepted measurements that represent biological conditions during economic development. Weight, after controlling for height, is an additional measure for current net nutrition. Little is known about how weights varied among Mexicans living in the nineteenth century American West. Between 1870 and 1920, average Mexican weight was low and remained constant. Mexican farmers had the heaviest weights, and unskilled worker weights were low. Weight of Mexican-born individuals were higher than Mexicans born in the United States at low weights but lower at high weights. For combined characteristics, weight varied the most with age, an uncontrollable characteristic, indicating that nineteenth century Mexican current net nutrition varied the most with factors over which they had no control.
