found to be only .0045, instead of the normal .006 to .0075

Hicks 2 found in the fluid from an ovarian cyst, small trans- 

 parent colorless globular bodies which had been detached 

 from red blood-corpuscles, and which were of a diameter of 

 about the l0 ^ 0Q of an inch. 



Laptschinsky reported 3 finding very small corpuscles, 

 only | as large as the normal ones, in conditions of the body ac- 

 companied with high fever, especially in infectious diseases. 



Hdyem has come to the conclusion 4 that in anemia the 

 blood-corpuscles are in general smaller than in normal con- 

 ditions ; but that the extremes which are met with are greater, 

 viz. .0022 and .010 to .014 Mm. 



Piper found in a case of " ulcerated scrotum and inflamed 

 testicle, with apparently tuberculous deposit in the gland," 

 "on one and the same slide, specimens which measure T ^r °^ 

 an inch ; while on other parts of the same slide alike exten- 

 sive fields of corpuscles which measure only a fraction less 

 than the classic 3 ^ - - of an inch."f 



Ponfick* Osier, i and Obermeier,* have reported other 

 abnormities]. 



According to Richardson,* the variations above and below 

 the standard size of corpuscles from any particular animal are
