A. Vesico-defferentialis 



This has been very fully studied by Fraenkel (1901) and Levi 

 (1902) ; they find it a branch of the umbilical in 94 per cent., in 

 other cases it springs from the prostatic and the pudendal. Henle 

 (1868) and Tschaussow (1886) saw the vessel very large. 



A. Uterina 



Nagel (1896) associated the artery with the hypogastric, the 

 obturator, and the vesico-vaginal. Levi (1902) found it con- 

 stantly a branch of the umbilical ; this agrees with Souligoux 

 (1894). He also reported that the artery passed 8 cm. from the 

 ureter. Parsons (1896) found the artery a branch of the hypo- 

 gastric in 50 per cent. 



There is some disagreement on the terminal relations of the 

 uterine and ovarian arteries which will require more investigation 

 to settle. The different opinions are fairly represented by Henle 

 (1868), Waldeyer (1895), Broeckhart (1802), and Souligoux 

 (1894); the question is whether there is or is not a circulus 

 arteriosum Huguieri. General studies of the artery have been 

 made by Ricard (1887), Fredet (1899), Freund (1904), and 

 Redlich (1909). 



A. Hcemorrhoidalis Media 



Levi (1902) found it an inconstant branch, present in Gy per 

 cent. ; in the majority of cases it arose from the pudendal. Wal- 

 deyer attributed little importance to it. 



A. Pudenda Interna 



This is the second trunk to develop from the hypogastric; it is 

 not infrequently associated with other branches, as I have shown 

 was the condition developmentally. Occasionally it leaves the 

 ischiadic at the spine, Levi (1902). It may terminate in the 

 perineal, while the artery to the external genitals may come from 

 the obturator, Miinz (1821), Green (1830), Labatt (1837), 

 Schwegel (1859), or from the epigastric, Quain (1844), Fried- 

 lowsky (1868). More frequently the artery is associated with the 

 inferior vesicle, Haller (1749), Friedlowsky (1869), Tschaussow
