183. We sliould not omit altogether to notice the aggre 

 gated fruits, such as the Pine-cone (Fig. 300), Pine-apple, 

 &Q. These fruits are composed not merely of the pistil, but 

 of the entire flower, or even of the whole inflorescence, bracts 

 and all, grown thick, and consolidated into one fleshy mass. 

 This is evidently the nature of the Pine- apple and of the 

 Mulberry.
