bacteria of putrefaction. 



Mr. Pellew, in describing the preparations exhibited by him, 

 said that the slide showing " Bacteria of Putrefaction " illus- 

 trated the care that must be taken when tissues are examined 

 for specific bacteria. The preparation was a section of human 

 liver in a case of typhoid fever. On double staining, quantities 

 of bacteria appeared which did not, however, resemble typhoid 

 bacilli, either in shape, size, or mode of grouping. On inquiry, 

 it was ascertained that the organs had been left exposed some 

 time before immersing in alcohol, hence they were quite honey- 

 combed by these putrefactive bacteria of all sorts. 



liverworts. 



The President read a paper on Liverworts, in explanation of 

 the specimens exhibited by him. 



Mr, Briggs presented to the Society fourteen slides of mica, 

 prepared for use with the polariscope. On motion the thanks 

 of the Society were tendered to the donor.
