 miles round Todmorden, within the last thirty years ; probably we may have 

 a greater number of species in this radius than most other districts of the 

 same extent. This, no doubt is owing partly to the great diversity of surface, 

 and to the different degrees of altitude, affording a variety of aspects and 

 different degrees of light and shade. 



But, I am sorry to say that a considerable number of species have dis- 

 appeared from the neighbourhood within the last ten or fifteen years from some 

 cause or other, and there are some that were pretty common, which are sel- 

 dom met with now, and are not so fine and healthy as they were formerly. 



However, we have a goodly number of species that are not frequently met 

 with in some other districts of the same extent. Of these I will mention a
