II ERMAPIIRODITISM. 



woman at the middle period of life, without 

 any indications of the catamcnial fluid being 

 merely mechanically retained, we may perhaps 

 suspect with reasonable probability the exist- 

 ence of a diseased state which has destroyed 

 either successively or simultaneously the func- 

 tions of both ovaries. In such a case the dis- 

 tinctive secondary peculiarities of the female 

 sex come to give place to those of the male. 

 Thus Vaulevier mentions an instance in which 

 menstruation suddenly ceased in a young and 

 apparently healthy woman ; no general or local 

 disease followed ; but soon afterwards a perfect 

 beard began to grow upon her face.* Again, 

 in women who have passed the period of their 

 menstrual and child-bearing life, and in whom 

 consequently the functions and often the healthy 

 structure of the ovaries are lost or destroyed, we 

 have frequently an opportunity of observing a 

 similar tendency towards an assumption of 

 some of the peculiarities of the male ; an in- 

 crease of hair often appears upon the face, the 

 mammae diminish in size, the voice becomes 

 stronger and deeper toned, the elegance of the 

 female form and contour of body is lost, and 

 frequently the mind exhibits a more determined 

 and masculine cast. Women, both young 

 and aged, with this tendency to the male cha- 

 racter, are repeatedly alluded to by the Homan 

 authors under the name of viragines ; and Ilip- 

 pocratesf has left us the description of two 

 well-marked instances. 



Among the females of the lower animals a 

 similar approach to the male character in the 

 general system not unfrequently shows itself 

 as an effect both of disease and malformation 

 of the sexual organs, and also in consequence 

 of the cessation of the powers of reproduction 

 in the course of advanced age. Female deer 

 are sometimes observed to become provided at 

 puberty with the horns of the stag,j and such

animals are generally observed to be barren,* 

 probably in consequence either of a congenital 

 or acquired morbid condition of their ovaries 

 or other reproductive organs. In old age, also, 

 after the term of their reproductive life has 

 ceased, female deer sometimes acquire the 

 horns of the male in a more or less perfect de- 

 gree ;f and Burdach alleges that roes sometimes 

 become provided with short horns when they 

 are kept from the male during the rutting sea- 

 son, and at the same time furnished with abun- 

 dant nourishment.! Mehliss alludes to two 

 cases in which a virilescent type was shewn 

 principally in the hair of the female deer. In 

 one of these instances the hair of the head, 

 neck, and abdomen, the shape of the ears and 

 extremities, and the odour of the animal, gave 

 it the closest resemblance to the male, and it 

 followed the other females as if urged by sexual 

 desire. 



This kind of acquired hermaphroditism in 

 aged females has, however, been moie fre- 

 quently and carefully attended to as it occurs 

 in Birds than as met with among the Mamma- 

 lia, the change to virilescence in the former 

 being more marked and striking than in the 

 latter, owing to the great difference which gene- 

 rally exists between the plumage of the male 

 and female. || When old female birds live for 

 any considerable period after their ovaries have 

 ceased to produce eggs, they are usually ob- 

 served to assume gradually more or less of the 

 plumage and voice, and sometimes the habits 

 also of the male of their own species. This 

 curious fact, first pointed out by Aristotle^I in 

 relation to the domestic fowl, has now been 

 seen to occur in a number of other species of 

 birds, but particularly among the Gallinaceae. 

 It has been in modern times remarked in the 

 common fowl ( Phusiunus gallus ) by Tucker, 

 Butler, and Jameson ; in the common pheasant 

 (P. colcliicus) by Hunter and Isidore St. 

 Ililaire; in the golden pheasant (P.pictus) 

 by Blumenbach and St. Hilaire ; in the silver 

 pheasant (P. nychemerus) by Bechstein and 

 St. Hilaire ; in the turkey ( Mdeugrls) by 

 Bechstein ; in the pea-hen (1'avo) by Hunter 

 and Jameson; ana in the partridge (Tetrao 

 penlrix) by Montagu and Yarrell. Among 

 theCursores it is mentioned as having occurred 

 in the bustard (Otis) by Tiedemann, and in 

 the American pelican (Platalea tiiaiu) by 

 Catesby. In the order Palmipeds; it has been 

 observed by Tiedemann and Itumball in the

|| It occurs also more frequently among birds 

 than among mammalia, from the former possessing 

 only a single ovary.
