 eggs, or one hundred and forty-eight hens' eggs, 

 or thirty thousand humming birds' eggs ; and

 for Gargantua himself.

 size of the bird that laid it, for a large bird 

 may lay a small egg, or a small bird a large 

 one. Comparing the egg of the great JNIoa 

 with that of our ^pyornis one might think 

 the latter much the larger bird, say twelve feet 

 in height, when the facts in the case are that
