fleeted images are seen as one, thereby giving the ap- 

 pearance of solidity and relief. The stereoscope is 

 used in the treatment of strabismus, in which con- 

 dition it serves as an excellent means of ocular gym- 

 nastics. It is also of service in optometry to nullify 

 convergence and diminish accommodation. 



Stereoscopic (ster-e-o-skop' -ik) [crepeoc, solid; oiumeiv,

Sterile (ster'-il) [sterilis, barren]. Not fertile or capable 

 of reproducing ; applied mainly to females, free 

 from microorganisms or spores. 



Sterility (ste-ril'-it-e) [sterilitas\ The condition of be- 

 ing sterile, infertile, or incapable of reproducing. S., 

 Facultative, sterility caused by the prevention of 

 conception. S., Idiopathic. See Azoosper mutism. 

 S., Relative, sterility due to other causes than abnor- 

 mality of the sexual organs. 



Sterilization (ster-il-iz-a' -shun) [sterilis, barren]. The 

 condition of rendering sterile, infertile, or incapable 

 of reproducing. In bacteriology, the destruction by 

 heat of the spores or mature forms of bacilli, micro- 

 cocci, or other forms of microscopic life. In most in- 

 stances a temperature of ioo° C. (212 F.) devital- 

 izes not only the mature forms, but the spores as well. 

 In a few instances this temperature is not fatal to 

 either. This, e. g., is the case with B. tenuis, the 

 rods resisting loo° and the spores 115°. S., 

 Hueppe's Method of, the repeated exposure to a 

 temperature of from 5 2 to 65 ° C. S., Intermit- 

 tent, a method of sterilization of organic infusions 

 introduced by Prof. Tyndall, in which an interval 

 of time is allowed to elapse between the several 

 heatings, giving an opportunity for any spores present 

 to develop into adult microbes, in which form they 

 readily succumb to the action of heat. S.-test, 

 Hochenegg's, the surgical dressings are impregnated 

 with a mixture composed of 150 parts of a solution of 

 aluminum acetate of the Austrian Pharmacopeia, 150 

 parts water, and 5 parts of a 21 per cent, paste of

 exposure to the temperature of boiling water becomes 

 bright-red.
