Blood globules, Blood-corpuscles, Blood-disks, Blood-vesicles, are small, circular bodies, which are particularly observable when the transparent parts of cold-blooded animals are examined by the aid of the microscope; and are met with in the blood of all animals. They are circular in the mammalia, and elliptical in birds and cold-blooded animals; are flat in all animals, and generally composed of a central nucleus enclosed in a membranous sac. Chemically, they consist of haematin and globulin-haemato-globulin. The chemical composition of the nucleus, where it exists,-it does not in man,-has been by some regarded as fibrin; by others, as fat; and by others, again, as a species of horn, to which the name nuclein has been given. Besides these, the blood contains white globules, (F.) Globules blancs, Leucocytes, which are probably lymph and chyle corpuscles in process of development into red corpuscles. Dried blood globules of the ox have been given internally in cases of anaemia.
