Under the kilt...

The American tourist stood staring at the highland sentry standing guard outside Edinburgh Castle.

After a few minutes she went up to the sentry and asked 'I've always wanted to find out what's worn under the kilt'.

The sentry replied: 'There is nothing worn, Ma'am, its all in perfect working order'.

Francis Maitland Balfour

Born 10 Nov 1851; died 19 Jul 1882 at age 30. British zoologist, younger brother of the statesman Arthur James Balfour, and a founder of modern embryology. Influenced by the work of Michael Foster, with whom he wrote Elements of Embryology (1883), Balfour showed the evolutionary connection between vertebrates and certain invertebrates (similar to research being done by Aleksandr Kovalevski). Balfour proposed the term Chordata for all animals possessing a notochord at some stage in their development. He also did pioneer work on the development of the kidneys and related organs, as well as the spinal nervous system. While convalescing from typhoid fever in Switzerland, he died at the young age of 30 from a fall while attempting an ascent of the unconquered Aiguille Blanche of Mont Blanc.
