As seen from this equation, the new base, although unmistakeably 

 corresponding to 2 molecules of ammonia, like many other poly- 

 ammonias, is monoacid.

(Abstract.) 



In this paper the author gives an account of certain tubular and 

 vesicular bodies which he has discovered in the spermatic cord, and 

 which he considers to be the remains of the Wolffian body of the 

 embryo. 



The structures in question, which he proposes to designate col- 

 lectively by the term " Corps Innomine," form a small group situated 

 behind the tunica vaginalis, between that membrane and the spermatic 

 vessels, and extending usually from the head of the epididymis as 

 high as the point where the membrane is reflected forwards from the 

 cord ; sometimes, however, reaching much higher up, or, on the 

 other hand, being more concentrated in the neighbourhood of the 

 epididymis. 



The " Corps Innomine" is found in the new-born infant, and in a 

 more or less modified condition at all later periods of life; it has 

 also been met with in the lower animals. To facilitate its detection 

 and examination, the author has found it advantageous previously to 

 render the surrounding tissues transparent, by macerating the sper- 

 matic cord in an acid solution, for which purpose he recommends the 

 use of tartaric or citric acid in the infant, and of dilute nitric acid in 

 the adult.
