The corrugated and star-like blood-cells abound inthe blood of the portal, though not in that of the hepat-ic vein. If their appearance arises from their tendencyto disintegration, this is no more than might be expect-ed in view of the functions of the liver. That the stel-lated aspect is an indication of a commencing disorgan-ization, or other profound change, may be illustrated byan examination of the action of water on normal blood-cells, which, if they be exposed to that liquid, undergo What is the duty of the plasma and the discs respectively ? Inwhat particulars may the discs he considered as individuals? Un-der what circumstances may they become corrugated ? What is theaction of water upon thorn ? E 2 106 ASSOCIATION OF H^EMATIN AND a distention; their thickness increasing more rapidlythan their diameter, they lose their concavity, becomeconvex, and at last appear as spheres of a less size thanthe original discs. When the quantity of water theyhave received has distended them to their utmost capac-, ity, they are invisible; but when it is withdrawn fromthem by establishing exos-mosis through the additionof saline substances, theymay reappear in the corru-gated or star shape, as seenin the photograph, Fig. respect to the ac-tion of the hsematin, it may-be observed that other ni-trogenized coloring materi-als present a similar relation Stellated blood-cells magnified 500 di- to Oxygen. As an example, ameters indigo may be mentioned. I consider that the properties of this substance illustratein a significant manner the properties of hsematin in thesystem. Indigo occu
