April 1850
How all-pervading & deeply seated is the affinity of organisms, the naturalist feels, who after examining a group of beings, & perhaps with still clo more impressively after examining ancient animals, comes back to some well-known form & now see that some obscure ridge, or point or curve or suture observ before absolutely overlooked is clearly connected with some great point of structure in the animals which he has lately been examining.— These f ridges &c are evidently unimportant & were overlooked — The naturalist must marvel over this.— What does this mean? I answer lineally descended or co-descendants from common stock, & receives same explanation as likeness in same race or family.
