Haemocyahin of Octopiis macropus. No investigation on the crystallization of the haemocyanin of Octopiis macropus is found in the literature. I have crystalli- zed it with the sanie facility as that of Octopiis viilgaris, but I have not obtained, as yet, the characteristical " projectiles " of the haemocyanin of Octopus vulgarls. It has always crystallized in needles, which may attain a very great length. They are repre- sented in fig. Fig. fi. — Haemocyanin-crystals from the blood of Octopus macropus. On recrystallizing it I have always obtained the same cry- stalline forms. Parahaemocyanin. 1 will observe here that, on allowing the glass containing the crystals and the mother liquor to stand for some time, the cry- 7.
