The second showing still further advance, there being now two auricles, thus assuming 

 the permanent character in the higher classes of animals. 



A second paper, by George Shadbolt, Esq., being " A Short Description of M. 

 Nachet's Prisms for the Oblique Illumination of Transparent Objects on the Stage of 

 the Microscope, with formulae for their construction, and observations on their use," 

 was also read. Iu this paper, the author fully described the construction and use of 

 this valuable addition to the microscope, and gave a mathematical demonstration

 nation. — J. W.
