Monthly Meeting held on November 17th, 1890, Mr. E. D. 

 Marquand in the chair. 



There was a very fair attendance of members, and five 

 visitors. The minutes of the last meeting having been read 

 and confirmed, the Rev. Joseph Woodhouse was elected 

 member of the Society. 



Mr. Luff exhibited living specimens of the Furze Mite 

 (Tetranychus ulicis or Acarus coccineus), and read a descrip-

Mr. F. Rose then read an interesting paper on " Some 

 notable Oral Equipments of the Yertebrata. Part II., Mam- 

 malia," This he illustrated with a large number of admirably 

 executed diagrams. An interesting discussion followed the 

 reading of the paper, which will be found on page 48 of the 

 present volume.

 the oxyhydrogen projecting microscope, but, unfortunately,

 crabs, lobsters, &c, cast their shells on the occasions of their 

 successive stages of growth. The question was ably opened

 old shell. He was followed by Mr. Rose, surgeon-dentist,
