He also observed chaufjes of Hlia])e; for, speakinj^ of the l)lood-cori)iiscles of a lobster, he said: But there is a curious chanj^e pro- duced in their shape by being exposed to the air; for, soon after they are received on the j^lass, they are corrufjated, or from a flat shape are changed into irregular spheres, as is represented in Plate XII., No. 12;* and on turning to the jilate we find represented angular, rosette, and stel- lated forms. He was the first wlio likened the appearance of coi'j)uscles, with tlieir external surface corrugated, to tliat of small mulberries, t It would be impossible for me, as well as useless, to give a list of all those who have described changes of form in red blood-corpuscles since Hewson's time. Different shapes—and some of them far more curious and irregular than those I have described — have been observed, imdev many physiological and pathological conditions, as well as on subjecting the l)lood to the action of various chemical and physical agencies. Text-books and monogi-aphs give sufficient information on this point, especially the article on the blood by Alexander Kollet, in Strieker's Handbuch der Lehre von den Geweben des Menschen uud der Thiere, which has been translated by Henry Power and published by the London New Sydenham Society, and which has been repub- lished in this country. X Since that article was written the following observations have been made : Langhans,!^! in experiments on rabbits, saw, in extravasated blood, red corpuscles with numerous tine projections, and in pigeons' red blood-cor- puscles, also, observed morphological changes. Lieberkiihn || described remarkable form-changes in the red corpuscles of the blood of salamanders and of pikes. WedlH observed changes of shape in human and frogs' red blood-corpuscles on adding a drop of concentrated aqueous solution of pyrogallic acid to a drop of fresh blood. Ray Lankester*'* found in his own healthy blood, in addition to the ordi- nary biconcave forms, thorn-apple and single and double watch-glass forms. In the two latter there is, Avhen the corpuscle is seen on edge, instead of a concavity, a convexity on either one or both sides. He also described and figured varieties of shape in both human and frogs' colored blood- corpuscles subjected to the action of various re-agents. Of these I shall cite, later on, the effects of very dilute ammonia gas and acetic acid vapor. Braxton Hicks ft observed colored blood-corpuscles of various shapes in fluid from an ovarian cyst, and in blood in other pathological conditions. * Ihid., p. 321.
