“The yellow fever alarm of 1804-1805 gave rise to the use of a rastel at Marseille, ... ; but there seems to be no record of letters being chisel-slit at Marseille in this period.” (Pratique XXXVII, page 2013/7)
Has anyone a letter with a rastel perforation from 1804/05 disinfected at Marseille?
I have a letter from Constantinople via Marseille to Tarragona. The letter has a rastel perforation but shows no signs of disinfection with vinegar. I'm not sure if the letter was disinfected at Semlin or at Marseille. I'm interested in your opinion.
