At about this time the palate bone is well developed and overlaps the 
palatine process of the maxilla. A little later (263, b, 1) a small palatine 
process arises from the premaxillary process and in older stages (300) 
Fic. 2. Embryo No. 284 (54 mm. long), enlarged nearly 214 diameters. 
Immediately beneath the squamo-zygomatic the alisphenoid may be seen. 
the bony palate reaches nearly to the vomer. In this embryo the infra- 
temporal and orbital plates are well formed, and the bone is well hollowed 
out, forming the well-marked hiatus which communicates freely with the 
cavity of the nose.
