Mr. Henry Ullyett proposed a vote of thanks to Dr. Eastes, and 
took the opportunity of calling attention to one or two points of 
interest—the way in which the jaws were united in birds and in 
some reptiles, thus showing their connection. It enabled them to 
gape and swallow substances very much larger than could otherwise 
be got down, and it supported the theory of those who believed 
that some of the birds were developed from reptiles, Turtles and 
lizards, he remarked, had horny beaks and no teeth, and fossil 
birds were found with actual teeth. He also referred to cases of 
malformation of beaks which had come under his notice. 
Mr. Nicholson seconded the vote of thanks, which was heartily 
-accorded. 
Mr. Walton asked Dr. Eastes if he had given any attention to 
the point as to what class of beaks made the most perfect nests. 
Dr. Eastes replied that he had not. 
Mr. Hills asked if anyone could give the reason for the pro- 
tuberauce on the head of a hornbill ? Was it used as a protection ? 
Colonel Frere said he lived in the land where those birds were 
‘eommon. It was subject to terrific monsoons, and the birds 
selected trees with a proper sized hole in it; the female took her 
place, and the male commenced to plaster up the hole, leaving 
nothing of his mate sticking out but just the head, and there she 
had to sit till the nesting was over. The protuberance was a kind 
-of gutter, and it prevented the rain from running into the nest. 
‘The bird used a quantity of yellow oil in dressing its plumage 
to protect it from the wet. 
Mr. Ullyett remarked that it might be what Darwin told them 
was ‘‘female development.” The females selected the male with 
the grandest and most perfect protuberance on its beak.
