Bovril was a very salty meat based product that became popular in the late 1800's for family use and also for use by the military as a food supplement for soldiers. It was a thick syrupy mixture that could be used as a spread on bread and crackers; it could be mixed with water to make a broth; or it could be used as a seasoning and flavoring addition in various soups and stews. It came in dark amber bottles in several sizes including 1/2, 1, 2, 4, 8, and 16 ounces. A set of these odd shaped bottles makes an interesting display and appears to be a measuring set. These bottles date from about 1920.
