XXXV.— DESCEIPTION OF A CONGENITAL TUMOUE 



OF THE TESTIS* 



This tumour was removed by Dr. James Duncan from a boy 

 eight years old. When the tunica vaginalis was cut into, a 

 considerable quantity of matter mixed with hairs was evacu-

It consisted almost entirely of fibrous texture, inclosing 

 fat-cells in its areola, and, at variable distances throughout,

Near the reflection of the tunica vaginalis, on the surface 

 of the testis, two club-shaped projections were attached, 

 covered by a layer of a substance resembling the ordinary 

 integument, with a quantity of fatty cuticular debris upon it. 

 This portion of integument somewhat suddenly became con- 

 tinuous with the surface of the tunica vaginalis. 



On the surface of the club-shaped projections, and at the 

 angle of reflection of the tunica vaginalis, numerous long hairs 

 were attached by bulbs. These hairs, of one-half to three- 

 fourths of an inch in length, were conical, pointed, and of two 

 kinds, some having their conical pulp-cavities prolonged in the

 with the exception of their conical pulp-cavities, solid. 



The integumentary membrane in which the hairs were
