Figures 188-196. — Basophils from circulating blood — mature, immature, and smudged cells. 2,470X. 



Figures 188-192: Normal mature, basophils, all of which 

 show slight to extensive artifacts due to the water used with 

 Wright's staining technic. 



188 Basophil having an appearance approaching that 

 following methyl alcohol fixation, figure 390. 



189 Basophil showing early artifact of coalescence and 

 dispersion of granules. 



190 Basophil showing moderate artifact of coalescence 

 of granules above the nucleus and discharge from 

 the cell surface. 



191 Basophil showing exten.sive artifact. Complete loss 

 of cytoplasmic granules except for two pairs on the 



cell margin and those above the nucleus that 

 coalesced when the cell dried. 



192 Basophil showing extensive artifact. Magenta 

 masses above the nucleus represent basophilic gran- 

 ules of the cytosome, not basochromatin of the 

 nucleus. 



193 Basophil promyelocyte. 



Figures 194-196: Technic artifacts, smudged cells. 



194 Slightly smudged basophil. 



195 Moderately smudged basophil. 



196 Extensively smudged basophil.
