The Pineal Eye.—Several papers have appeared in the past two 
years treating of this organ. Possibly those of Leydig! have attracted 
most attention. Leydig was the first to suggest that this might be a 
sense organ, but in these later papers he takes the ground that the 
pineal gland is a lymph gland, and that the ‘‘ nerve cord, which has 
been described as connecting it with the brain, isin reality a strand of 
connective tissue. On account of the author’s position as a histolo- 
gist, these views are certainly entitled to weight, but connective tissue 
of ectodermal origin is certainly an anomaly. Professor A. P. W. 
homas, in an article on the development of Sphenodon,* states that 
in the recently hatched tuatara the pineal eye still shows as a sey 
spot through the translucent skin over the parietal foramen. This 
ave been able to observe even in a tuatara-eight inches in length. 
But as the tuatara grows older the skin over the pineal eye eS 
more opaque, and though in some individuals the scantier i oe 
‘Ment of the pigment over the parietal foramem affords a feeble indica
