predominated, and from some other similar cases it follows, 

 that the rudiment of the uterus of a male hermaphrodite may 

 resemble considerably the female uterus ; and inversely the 

 uterus of a female hermaphrodite may also resemble the rudi- 

 mental uterus of a male. (Is the third lobe of the prostate 

 Weber's rudimentary uterus enlarged ?) 



5. — The re-establishment of the voice in dead bodies. By M. 



Blandet. 

 Physiological anatomy has been my sole guide in arriving 

 at the artificial emission of sounds from the larynx : being 

 acquainted with the play of the muscles of that organ, I have 

 imitated their action by a mechanism analogous in its effects : 

 my finger supplying the muscular contraction. I fix the 

 thyroid cartilage between four fingers which are thus held as 

 a clarionet, because the hyo and sterno-thyroid muscles cause 

 a similar tension. I then press the index finger on each of the 

 pyramidal apophyses of the arytenoid cartilages which are 

 brought into contact as if by the thyro-arytenoid muscle. 

 This pressure is so constant during life that it produces at 

 this point on the cordae vocales a nodule, which is not yet 

 described. In the last place I blow through the trachea, and 

 I produce sounds clear and shrill, such as theory would lead 

 us to expect, because the contact of the two apophyses 

 diminishes the length of the cordae vocales where it estab- 

 lishes the nodes of vibration. The action of the crico-thyroid 

 muscle is imitated by pressing on the base of the thyroid 

 cartilage, and that of the lateral crico-arytenoid by lifting 

 with the nail the external edge of the arytenoid cartilages. 

 I here approximate these cartilages as the arytenoid does, or 

 I draw them down by the base as the posterior crico-arytenoid 

 do. By these operations I produce very extended gamuts, 

 such as the voice of expiration ; that of inspiration is still 

 stronger and more easily obtained, because the vibrating plates 

 of the larynx, i. e. the corda? vocales present their bodies
