Mr. Hyde exhibited a specimen of the Lancelet Amphi- 

 oxus or Branchiostoma Lanceolatum, from the Mediter-

Prof Dreschfeld gave a demonstration of some Micro- 

 organisms found to be present in connection with certain 

 diseases. 



In the course of his remarks, Dr. Dreschfeld said that

 Micrococci, Bacteria, Bacilli, and Spirilla. The Micrococci 

 were little rounded organisms consisting of simple pro- 

 toplasm, found singly or in pairs, or linked together to 

 form chains, or in masses. When in a free state they 

 showed distinct movement. They all stained readily with 

 aniline dyes. They had been found in cases of Pneumonia 

 and Erysipelas, and were believed to have been met with 

 in Diphtheria. The Bacteria were small rod-shaped organ-
