XXXV. DESCRIPTION OF A CONGENITAL TUMOUR 

 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- 

 ated. The tumour possessed the following characters : A 

 mass of an irregular ovoidal form, about the size of the last 

 joint of the forefinger, appeared to be the testis, so much 

 altered in texture as to present no trace of its original 

 structure. 



It consisted almost entirely of fibrous texture, inclosing 

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

 small tubercular masses of a light yellow tough substance, of 

 a granular aspect, resembling some forms of scrofulous deposit. 



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 

 form of canals, full of cells to their extremities ; others were, 

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



The integumentary membrane in which the hairs were
