 ing the shape of a globe or sphere. 



Globularia (glob-u- la' '-re-ah) [globulus, a little ball]. 

 A genus of selaginaceous herbs and shrubs. G. aly- 

 pum, of the old world, affords leaves that are a good 

 substitute for senna. G. puticosa and G. vulgaris 

 have similar properties.

Globulin (glob'-u-lin) [globulus, a little ball]. 1. A 

 general name for various proteids comprising globulin, 

 vitellin, paraglobulin, or serum-globulin, fibrinogen, 

 myosin, and globin, which differ from the albumins in 

 not being soluble in water ; one species, existing in the 

 crystalline lens, is specially designated as globulin. 

 They are insoluble in distilled water, but soluble in 

 dilute neutral saline solutions. These solutions are 

 coagulated by heat, and precipitated by a large amount 

 of water. They yield acid-albumin when acted upon 

 by dilute acids, and alkali-albumin when acted upon 

 by dilute alkalies. Vegetable Globulins have been 

 studied, and named vegetable ?nyosin, vitellin, and 

 paraglobulin ; they are found in the seeds of plants.

 product of the gastric digestion of a globulin. 



Globulus (glob'-u-lus) [L.]. The Nucleus globuliformis 

 of the cerebellum. It is a mass of gray matter between 

 the fastigatum and the embolus. 



Globus (glo' -bus) [L.]. A ball or globe. G. epidid- 

 ymis. Sec Epididymis. G. hystericus, the " lump" 

 or choking sensation occurring in hysteria, caused 

 probably by spasmodic contraction of the esoph 

 and pharyngeal muscles. G. major, the larger end 

 or head of the epididymis. G. minor, the lower end

 part of the lenticular nucleus. 



Glochidiate (glo-kid'-e-af) [yAu^/c, a projecting point]. 

 In biology, barbed. Tipped with barbs, or with a 

 doubly-hooked point. 



Glochidium (glo-kid' -e-unt) [yAuxk, a P 1 '"' 

 point: //., Glochidia]. In biology, a stage in the 

 development of lamellibranchiate molluscs [ < 

 Anodon\, the ova of which develop up to a certain 

 stage in the gill-pouches of the parent, and remain 

 there as glochidia until some fish or wading bird eomes 

 into their vicinity, when the glochidia issue forth, and, 

 swimming as Pectens by the flapping of their valves,
