Hemoglobinometer with three glass bottles, lenses, tubing, and a tally counter, stored in a leather case. These apparatuses were used in the early 20th century to measure hemoglobin levels in blood. Blood samples would be taken, diluted, and compared to tinted glass on the hemoglobinometer's comparator slide to determine hemoglobin level.
