the scalenus anticus, whose fibres are inserted into the upper border 

 of the cervical rib at its posterior part. These are fibres continued 

 across the outer surface of the rib, and slope forwards to be inserted 

 into the first rib, completely filling up the space between the two 

 bones. On the inside one or two fibres slope in the same direction as 

 the internal intercostal muscle, so that this part of the muscle between 

 the ribs may be described as an extra intercostal muscle. Behind 

 the rib is in relation with the deep muscles of the back of the neck. 

 The rib occurred also on the right side, the differences being 

 mostly in size, thus : 



Length 11-2 cm. outside measurement. 



7 - 7 cm. from outside angle to first dorsal rib articulation. 

 3-5 cm. from angle to body of seventh cervical vertebra.

Date of observation, February, 1905. 



A preauricidar appendage to the right pinna of a foetus of the later months of 



gestation. 



This is a cylindrical process which arises between and immedi- 

 ately in front of the tragus and the eras helicis. It first passes out- 

 wards and a little downwards, and then downwards and slightly 

 forwards, and terminates in a pointed extremity which is covered by 

 five or six hairs. The length is one centimetre, and the circumference 

 is '9 centimetre, but at what one might call its neck there is a slight 

 constriction. The relative proportion of its length to that of the pinna 

 is as two is to five. The pinna seems otherwise normal. 



On section it was found to consist microscopically of a rod of 

 yellow cartilage covered by skin. 



As to the cause, the process may have become in some way 

 lixcd to the amnion, and thus, as development proceeded, got pulled 

 outwards, or the tubercles forming the tragus and the cms helicis
