Tourists

A group of American tourists was being guided through an ancient castle in Europe.

"This place," the guide told them, "is 600 years old. Not a stone in it has been touched, nothing altered, nothing replaced in all those years."

"Wow," said one woman dryly, "they must have the same landlord I have."

James Glaisher

Born 7 Apr 1809; died 7 Feb 1903 at age 93. English meteorologist and aeronaut who, between 1862-66, mostly with Henry Tracey Coxwell, made balloon ascents, many of which were arranged by a committee of the British Association. The object was to carry out scientific observations such as the variation in temperature and humidity of the atmosphere at high elevations. On 5 Sep 1862, ascending from Wolverhampton, Glaisher and his companion attained the greatest height that had then been reached by a balloon carrying passengers. The precise altitude at the highest point is unknown because Glaisher lost consciousness and was unable to read the barometer, but estimated at 7 miles high. He produced dew-point tables (1847) and wrote several scientific books including Travels in the Air .«
