Humboldt's Instruments
The forty-two scientific devices — barometers, cyanometers, thermometers, chronometers — that Humboldt carried across the Americas: technologies of abstraction that augmented but did not replace the body's embodied perception.
Humboldt transported forty-two scientific instruments across the Atlantic in 1799 and employed them throughout his five-year American expedition: barometers for atmospheric pressure, thermometers for air and water temperature, sextants for celestial navigation, chronometers for longitude, electrometers for atmospheric electricity, cyanometers for the blue intensity of the sky, hygrometers for humidity, dipping needles for magnetic variation. Each instrument embodied a theory about the phenomenon it measured. Together they constituted the material infrastructure of embodied science — technologies of abstraction that refined what the body already perceived without substituting for the body's perception.

The instruments are central to the Humboldt volume's argument because they complicate the sharp distinction between embodied observation and disembodied processing. Humboldt did not perceive the temperature at Chimborazo's summit with his skin alone; he used a thermometer. He did not measure atmospheric pressure with his lungs alone; he used a barometer. Each instrument translated a bodily sensation into a number — a technology of abstraction, structurally analogous
