Dear Father

I send you a quotation from Trousseau showing what a difference a very slight change in the conditions of life may make—

“I stated at the beginning of this Lecture that it is a frequent occurence for young girls on arriving in Paris to have suppression of the catamenia. Change of residence is enough in itself to produce this result without there being any change in the manner of life. Young girls who have lived a number of years in a provincial boarding school, on moving to a similar institution in Paris where the régime is evidently the same; often experience an interruption of several months in their courses; and young girls removing from Paris to the country similarly suffer.” Lectures on Clinical Medicine by A. Trousseau— (New Sydenham Soc.) London. 1872— Vol V. p 213²
