The Book of Household Management by Mrs. Beeton

45. WHEN ANY OF THE CARRIAGES OF THE GUESTS ARE ANNOUNCED, or the time

for their departure arrived, they should make a slight intimation to the hostess, without, however, exciting any observation, that they are about to depart. If this cannot be done, however, without creating too much bustle, it will be better for the visitors to retire quietly without taking their leave. During the course of the week, the hostess will expect to receive from every guest a call, where it is possible, or cards expressing the gratification experienced from her entertainment. This attention is due to every lady for the pains and trouble she has been at, and tends to promote social, kindly feelings.
