 When noticed in other works, it is but perfunctorily, and in 

 a manner to indicate a collection from pollen or other parts 

 of plants ; and it was seen by Mr. Gulliver to contain a few 

 pollen-grains, some almost perfect, others disintegrated, but alto- 

 gether insufficient to form the essential composition. 



But, now, this is plainly proved to be one of the albuminoid 

 group, aflbrding an abundance of Mulder's protein, highly nitro- 

 genized, and with a molecular base, the whole evidently a true 

 animal secretion and by no means a mere collection. And thus 

 the queen-bee jelly is exactly such a nutrient matter as may be 

 rationally supposed most conducive to the growth and development 

 of the larva, just as milk is to young mammals, and the ingluvial 

 secretion of certain birds to their nestlings.
