469. Oxyhemoglobin of the Gray Fox (Urocynn i-nn-itn-iirijenteus), showing sphonelitic group* uf tliiu 



prismatic crystals, an occurrence rarely seen. 



470. Same, showing large masses of crystals in parallel growth, a characteristic aggregate in this 



species. 



471, 472. Same, showing radiating tufts that develop in retarded crystallizations. 

 473, 474. Same, showing shorter thicker crystals developed in undiluted preparations. These crystals 



formed in protein ring, and in 474 one of the small rare sphenelitic groups is seen.
