 a Fallopian tube, the seat of an extra-uterine preg- 

 nancy. It may also be due to the rupture of an ovary, 

 or of a vein in the broad ligament ; it may follow 

 an abortion, the blood escaping through the Fallo- 

 pian tube; or it may be due to retention of the 

 menstrual fluid with escape of the blood. Physical 

 examination, whatever may be the cause, reveals a 

 boggy swelling in Douglas's cul-de-sac.

 a cavity]. An effusion of blood into the peritoneal 

 cavity.

Hematocrit (hem' -at-o-krit)[aiua, blood; npirrjc, judge; 

 xpiveiv, to separate, to judge]. An instrument for 

 making volumetric estimation of the blood by sepa- 

 rating by centrifugal action the corpuscles from the 

 serum. A volume of blood and one of Midler's 

 liquid (to prevent coagulation) are placed together in 

 each of two small, thick-walled glass tubes, gradu- 

 ated in fifty parts. The tubes rest on brass holders 

 which are fixed on the axes of a revolving apparatus. 

 After some eight thousand revolutions in from five 

 to seven minutes, the process is complete. The 

 corpuscles and the salt-plasma are separated by a 

 narrow band of leukocytes. The instrument is useful 

 in comparing the blood of different individuals. 

 With a little practice the total error is not more 

 than one per cent.
