but actually greater than that found, in adult specimens. The con- 

 dition was found in young Eskimo, Negro, Australian, and European 

 skulls, and is probably associated with the more rapid growth of 

 the posterior region of the cranium during the first few years after 

 birth. 



(7) Professor E. Fawcett showed (a) two specimens in which the 

 Vermiform Appendix was absent. Both were obtained from adults, 

 and occurred in a series of 403 cases examined by himself and Dr 

 J. V. Blachford at the City and County Asylum of Bristol. In 

 neither case was there any sign of inflammation present, either recent 

 or old standing. In one case there was a small thickening at the 

 point of convergence of the longitudinal muscular gland of the large 

 intestine ; in the other, there seemed to be a slight hollow protrusion at 

 the same point. In one case the caecum measured in height 6 cm. 

 and in width 8 cm., in the other case it measured 7x7 cm.

 (see fig. 1). 



This small bone, which was evidently a detached part of the ridge 

 of the trapezium, with whose long axis its own long axis coincided, 

 measured 7 mm. in length by 3 in thickness. It was attached to the 

 palmar face of the trapezium by strong ligamentous bands. These

ligaments allowed it to be moved from side to side by the fingers. 

 There was no synovial cavity between the bones. By its lower 

 pole this bone was attached through two ligamentous bands to the 

 palmar aspect of the base of the 3rd metacarpal bone ; to its inner 

 side the anterior annular ligament of the carpus was attached. It 

 formed the lower part of the groove for the flexor carpi radialis 

 muscle. 



Another specimen exhibited to the Society showed the ridge of the 

 trapezium with a deep notcli in its anterior border. The part of the 

 ridge below this notch corresponded exactly \vith the bone above 

 described.
