stals became insoluble. I shall cali this insoluble modification 

 " parahaem ocy an in ". 



Haemocyanin of Eledone moscliata. 



Following the same method with the blood of Eledone mo- 

 schata, like Kobert (6), I bave always obtained needles. 

 A photograph of these crystais is seen in fig. 7. 



Fig. 7. — Haenioc3'aniii-crystals from the blood of Eledone moschata. 



Not eyen with the haemocj-anin of Eledone moschata bave 

 I obtained the characteristical " projectiles " of the haemocyanin 

 of Octopus vulgaris. 



ReassLiming, oxyhaeinocyanin may crystallize in the form of 

 "projectiles" or neeJies of a greenish-blue colour. 



The " projectiles " are characteristic to the haemocyanin of 

 Octopus vulgaris; the needles are common to the haemocyanin 

 of Octopus vulgaris, Octopus macropus and Eledone moschata. 



On recrystallization the haemocyanin-needles obtained from 

 the blood of Octopus vulgaris may pass into " projectiles ". 



The haemocyanin crystals of Octopus m'acropus may pass into 

 an insoluble modification which I bave called "parahaemo- 

 c y a n i n " .
