The following glossary of medical terms was assembled as part of a project on medicine from 1760-1830 but it includes some terms from a wider period. I have drawn on several sources, including, with the permission of the author, Medical Terms used in the late 18th Century which appeared on a now obsolete web site written my Melanie McClusky. Information from Dr Johnson's Dictionary, first published in 1755, is shown in red.
Figure 2 is a simple cartoon showing three different types of aquifers: confined, unconfined, and perched. Recharge zones are typically at higher altitudes but can occur wherever water enters an aquifer, such as from rain, snowmelt, river and reservoir leakage, or from irrigation.
The aquifer is the result of the dissolution of carbonate rocks by slightly acidic rainwater that seeps into the ground through fractures and joints. Once underground, the water slowly dissolves the soluble rocks into subterranean passages, caverns and caves. The result of this process is defined as a karst landscape. The mostly-dormant part of the Manitou Springs aquifer, now above the water table, is a cave system located north of the city called âCave of the Windsâ.
