80 STRUCTURE OF COLORED BLOOD-CORPUSCLES. 



Huels * described frogs' red blood-corpuscles acted on by carbolic acid. 



Fabert observed, in the urine of a patient with Bright' s disease, colored 

 blood-corpuscles of a great variety of different shapes, some of which showed 

 him phenomena of contractility and amosboid movement, "very similar" to 

 those of colorless blood-corpuscles. 



Hiiter \ reported seeing in the capillaries of the frog lung a few red blood- 

 corpuscles adhere to the sides by means of a drawn-out pedicle, with half the 

 body on each side, having a saddle-bag-like shape (" zwergsackalinlicli"}. 



Laptschinsky described and figured the effects of various re-agents, 

 among them aniline blue, magenta, and tannin, on the red blood-corpuscles 

 of triton and man. He confirmed and enlarged the older observations of 

 Roberts. || Laptschinsky H also described some variations of shape which he 

 met with on examining human blood in different diseases. 



Arnold, ** in the course of his observations on diapedesis of colored blood- 

 corpuscles after ligating the median vein of the frog's tongue, saw that in the 

 various phases of transit these corpuscles assumed various shapes, sometimes 

 pear-shaped, with slender stem, sometimes caudated, oval, etc. Similar 

 shapes have under similar circumstances been described by others. 



Hiller tt refuted the supposition of Hiiter (II. Deutscher Chirurgen Congress, 

 April 18, 1873), that the stellate and thorn-apple forms of red blood-corpus- 

 cles are due to immigration of monads into the substance of the corpuscles. 

 He found such forms in blood during febrile and non-febrile diseases ; they 

 were absent in some cases in which large quantities of monads had been in- 

 jected into the blood of animals ; and he observed in many cases their develop- 

 ment directly under the microscope. 



Rommelaere ft observed in various diseases changes of shape of the red 

 blood-corpuscles. 



Landois saw corpuscles assume, before their dissolution, a spherical 

 form with exceedingly fine points. 



Ebert,|||| Bottcher,HH Fuchs,*** and Schmidt ttt have reported variations of 

 the ordinary shape. The latter has also called attention to the fact that human 

 red blood-corpuscles, seen in exact profile and closely examined, are repre-
