I love that he purposely misspelled l'Hopital.
Who didn't think, back in their uni days; "Hey! That looks like a French Hospital, without an 's' "?
Note that l'Hospital's name is commonly seen spelled both "l'Hospital" (e.g., Maurer 1981, p. 426; Arfken 1985, p. 310) and "l'Hôpital" (e.g., Maurer 1981, p. 426; Gray 1997, p. 529), the two being equivalent in French spelling.
According to sources, this is a valid spelling.
