OxtpHAm Mroroscopicat Society. 
On Tuesday evening, the 18th October, at No. 2, High Street, a 
paper was read before the members of the above Society, by Mr. James 
Nield, “On British Ferns, microscopically considered.” The paper 
was illustrated by diagrams showing the parts much enlarged, and by 
a complete set of dried specimens, representing each genus, also by 
numerous specimens of the microscopic parts of ferns carefully mounted 
for observation, and which, after the paper was read, were submitted 
to very critical examination under several first-class binocular instru- 
ments, and called forth many expressions of wonder and delight. At 
the close a well-earned vote of thanks was accorded to Mr. Nield for 
his paper, which is one of a series to be read during the winter 
months.
