A Letter to a Friend (written 1656; published posthumously in 1690), by Sir Thomas Browne, the 17th century philosopher and physician, is a medical treatise of case-histories and witty speculations upon the human condition.

It is believed to be the source of a term Mary Leitao found in 2001 to describe her son's skin condition. She chose the name "Morgellons disease" from a skin condition described by Browne in Letter to a Friend, thus:

"... that endemial distemper of children in Languedoc, called the morgellons, wherein they critically break out with harsh hairs on their backs."[1]

There is, however, no suggestion that the symptoms described by Browne are linked to the alleged modern cases of Morgellons.
