The first of the specimens examined was from a young lion, about 18 months old, that had been shot and afterwards killed with chloroform. The specimen was received from the New York Zoological Park. The blood was 24 hours old and had been drawn into oxalate. It was ether-laked and centrifugalized, and from the clear solution the preparations were made. After covering, the blood soon begins to crystallize, but in this preparation only crystals of reduced hemoglobin were obtained. The laked blood crystallized in the test-tube. The second specimen was from the Philadel- phia Zoological Gardens, and was from an adult animal. In this blood, after the usual preparation as outlined above, there appeared at first crys- tals of reduced hemoglobin in the shape of rods or prisms; and later, as a sort of second crop, there appeared two types of crystals of oxyhemoglobin, both evidently with the same axial ratio, but with different development and a different prism. From these oxyhemoglobin crystals, and especially from this latter form, there developed, by paramorphous change, crystals of the metoxyhemoglobin that retained the form of the original oxyhemo- globin. The crystallographic characters did not appear to be influenced by the change from the one to the other material. Oxyhemoglobin of Felis leo. Orthorhombic: Axial ratio a : b : (5 = : 1 : Forms observed: Unit prism (110), macrodome (101), base (001), macropinacoid (100), brachypinacoid (010). Angles: Prism angle 110 A 1TO =74° 50' (normals); macrodome angle 101 A T01 = 63° 32'; prism to base 110 A 001 =90°, macropinacoid to brachypinacoid 100 A 010 =90°..
