Emerson's book provides info on the number of specimens in his collection. The rarest species, of which there are many, are represented by only one specimen. The more common specimens range from a few to an unspecified, large number.

Most of the time, he provides an exact count. Example: 232. Often, he provides a minimum value, such as 250, meaning that there were at least 250 specimens in the collection. Other times, he omits a number, but states the species is very common. These latter specimens are noted above as the number 1000.
