 tion. The superior profunda leaves the main stem ; the inferior 

 profunda and anastomotica magna leave the inner division.

Date of observation, June, 1904. 



Sex, male. 



Abnormal lung (right). 



The middle lobe is partially subdivided into two by the inferior 

 lobe. The upper and anterior division corresponds to the normal 

 middle lobe, while the lower and posterior division projects hori- 

 zontally outwards for 3^ inches like a tongue below the root of 

 the lung and behind the front and lower part of the inferior lobe. 

 The branch of the bronchus supplying this latter division came off 

 from the branch that supplied the middle lobe. The division probably 

 represents the lobus impar of certain mammals. The inferior lobe 

 shows an incomplete fissure, running horizontally outwards from the 

 junction of the oblique and horizontal fissures for 2 inches in length 

 and I inch deep. 



The corresponding left lung showed three lobes, and the eighth 

 pair of ribs were separate from the seventh and articulated with the 

 ensiform cartilage.

Abnormal costal attachments to sternum. 



In this case the eighth costal cartilages were prolonged almost to 

 the middle line. The extremities of the two costal cartilages did not 

 quite meet in front of the metasternum but were bound to one another, 

 to the ensiform and to the lower extremity of the gladiolus by fibrous 

 bands. The cartilage of the eighth rib articulated slightly with that 

 of the seventh rib on the right side. The cartilages on the left side 

 did not correspond in their attachments with those on the right, but 

 were more crushed together and '2 cm. lower down. The sternum
