| Neutrophils (human). Wright's stain. 1800x Note: 1. Neutrophils are 9-14 micrometres in diameter, 40-75% of WBCs in a blood smear; 2. they have a segmented or lobed nucleus; 3. cytoplasm has granules (0.1-0.4 um) that stain variably - light blue, azure, violet; 4. the arrow is pointing to a "drumstick formation" - inactive female X chromosome; 5. RBCs in "rouloux" formation. Ross, et al. p. 212 Plate 26 Fig. 3- |

| Eosinophils (human). Wright's stain. 1800x Note: 1. These are 10-14 um in diameter, 1-6% of WBCs in a blood smear; 2. they have a bilobed nucleus (like spectacles); 3. granules are relatively uniform in size, 0.6 um in diameter and are refractile. Ross, et al. p. 212 Plate 26 Fig. 1 & 2. |

| Basophils (human). Wright's stain. 1800x Note: 1. These are 8-14 um in diameter and <1% of WBCs in an blood smear; 2. the cytoplasmic granules are of variable size that stain intensely with methylene blue. Ross, et al. p. 212 Plate 26. Fig. 6 & 7. |
