\ 



295. a-Oxyhemoglobin of the Clround-hog (Marmnta mnnax), showing two groups nf hexagonal plates 



in partial orientation, looking complete as seen on liase. and one group seen in side view, showing 

 radiating character due to partial orientation. 



296. Same, showing larger group in this partial orientation, as seen on base and on edge. In these two 



figures the lath-shaped section of plates is illustrated. 



-!I7. Same, a very complex group in edge view, showing; arborescent form of group. 

 2!IS. j-Oxyhrmoglobin, showing arborescent and feathery forms of groups of crystals. 



299. Same, showing simpler group of crystals on base and on edge. 



300. Same, showing twinned group of crystals in polarized light, In 299 and 300 the imperfect curved
