B. G. Jefferis and J. L. Nichols, Searchlights on Health — Practical Rules on Table Manners (1919)
“ In eating game or poultry do not touch the bones with your fingers. To take a bone in the fingers for the purpose of picking it, is looked upon as being very inelegant.8. Never use your own knife or fork to help another. Use rather the knife or fork of the person you help.9. Never send your knife or fork, or either of them, on your plate when you send for second supply.10. Never turn your elbows out when you use your knife and fork. Keep them close to your sides. ”
