The subject of minute measure- 

 ments was discussed in an interest- 

 ing manner in an address before the 

 Microscopical Section of the A. A. 

 A. S. last year, an abstract of which 

 was published in this Journal, vol. 

 V, p. 181. 



The slight differences in size accu- 

 rately given in this table are not 

 always appreciable under modern 

 amplification, but vmder a power of 

 1,150 diameters 'corpuscles differing 

 by the i-iooooo of an inch are readily 

 discriminated.' For the conclusions 

 of Prof. Wormley as regards the 

 possibility of identifying blood of dif- 

 ferent animals, the reader is referred 

 to the brief review of Micro-Chemis- 

 try of Poisons, which will be found 

 in another column.
