(English) Autograph Letter Signed [to Henry Denny]. Down, Kent, June 1, 
VERY EARLY DARWIN INVESTIGATION OF THE RACES OF MAN. In 1834 Darwin heard that head lice vary among the races of man while on the voyage of the Beagle. In his Beagle zoological diary he wrote, “Mr Martial, a surgeon of an English Whaler assures me that the Lice of the Sandwich Islanders … if they strayed to the bodies of the English in 3 or 4 days died … If these facts were verified their interest would be great.— Man springing from one stock according his varieties having different species of parasites.— It leads one into many reflections.” Intrigued by the implications of this observation, Darwin began collecting specimens for further research.

(English) Autograph letter signed “Freud” on cigars to an unidentified correspondent “Honored Sir and Dear Brother.”. Vienna, May 26, 1921
FREUD’S CIGARS. In this fine letter Sigmund Freud asks a friend visiting Holland to bring back his beloved Dutch cigars, writing in small part, “Although I could just as well rely on your taste, in case you get to The Hague and make the purchase there, I’ll give you the address Hagen Spinecka and the brand Soberanos (1400 [presumably a series of the Soberanos brand] 15 dozen). The enclosed 60 florin note is to cover this purchase.” In turn-of-the-century Vienna, the Austrian government maintained strict control over the tobacco industry, and Freud relied on friends to bring him the cigars he smoked endlessly.
