The duct of Gartner. — The duet of (Jiirtner is a small tube, blind at both 

 extremities, which is occasionally found at the side of the neck of the uterus 

 and the up))er i)art of the vagina. It represents a section of the lower part of 

 the A\'olthan duct, and corresponds with a i)ortion of the vas deferens of the 

 male. 



MALE 



The hydatids of Morgagni. — Two hydatids of Morgagni are met with in the 

 male — the petlunculated and the sessile. The former is very inconstant; when 

 l)resent it is an oval or i)yriform vesicle, filled with clear fluid, which is attached 

 by a slender pedicle to the globus major of the epididymis. It corresponds with 

 the hydatid of Morgagni met with in the female, and it is the renniant of one of 

 the iijjper ^\'olttian tubules. The sessile hydatid is more frecjuently ]>resent. It 

 is also an ovoid vesicle, which is attached by its small end to either the U)>])er 

 extremity of the testicle or to the groove l)etween tlic testicle and the globus major. 

 It corresponds with the timjjriated end of the Fallo])ian tube in the female, for it 

 is a remnant of the ui)per end of the JSliillerian duct from which the Fallopian 

 tube is developed. 



The organ of Giraldes, or parepididymis. — This organ is a remnant of 

 some of the lower Wolttian tubules, and it corresi)onds with the i)arovarium of the 

 female. It lies in front of the lower part of the spermatic cord, aliove the epidid- 

 ymis, and either behind the up})er part of the tunica vaginalis or just above it. 

 The tubules of which it consists are small, yellowish in colour, and they are coiled 

 together, forming a small body, which is from 5 to 14 nun. in diameter (^ of an 

 inch). 



Vasa aberrantia. — When the tube of the ei)ididymis is uncoiled; several l)lind 

 diverticula arc found connected with it. They constitute the vasa aberrantia, and 

 the largest of them, which is usually found in the region of the globus minor, is 

 known as the vas aberrans of Haller. It varies in length from 4 to 37 cm. (1^ to 15 

 inches), and it is coiled into the form of a small mass 2 to 6 cm. (f to 3 inches) long, 

 which lies between the body of the ei)ididymis and the vas deferens. The exact 

 significance of the vasa aberrantia is not certain, l)Ut they are jirolxdjly the remains 

 of some of tlic \\'olthaii tubules. 



The uterus masculinus, or sinus pocularis. — The uterus masculinus lies in 

 the floor of the prostatic jwrtion of the urethra, where it oi>ens, innnediately in 

 front of the highest point of the verumontanum, by an oval ojiening. It is a 

 small cavity, 6 to 12 mm. Q to ^ of an inch) long, narrow at its opening into the 

 urethra, but it widens considerably towards its l)lind extremity. It lies behind 

 the middle lobe of the prostate gland and between the lateral lobes and the common 

 ejaculatory ducts. It is a renmant of the lower parts of the Miillerian ducts, from 

 which the uterus, vagina, and the Fallopian tubes are developed in the female, and 

 it corresponds, therefore, with the vagina, and possil)ly with the uterus of the 

 female. 



INTECiUMENT 



Hypertrichosis. — The condition of excessive hairiness to which the term 

 hypertrichosis is ai)]>lied only occurs occasionally, and it may be due cither to the 

 excessive develojmient of the secondary hairy covering which <levclops after birth. — 

 hvpertrichosis vera, — or to the ])ersistence and growth of the w(»olly covering or 

 lanugo which is formed over the surface of the body during intrauterine life, ami 

 which is usually cast off to make way for the secondary hairs. This latter condition 

 is called ])S(Midohv]iertrichosis lanuginosa. 



Supernumerary breasts and teats. — The occurrence of additional teats — 

 polvthelv — and additional niannna — i)olyma.sty — is by no means uncommon, the 

 ])ercentage of cases of additional mannnary structures varying in diflferent districts 

 from one-half to thirty per cent.
