 between some of these. It will be seen that the county 

 estimate above is taken much higher than actual records 

 at present show ; allowance being made for the recent dis- 

 crimination, and the inconspicuous size of the plant.

 a narrow range. Hence, it would appear, comes their 

 readiness to swell the number of species in their lists, by

 without due inquiry. Too slenderly acquainted with the 

 use and application of facts in science, they imagine that
