whether they penetrate the substance of the ovulum or not; 
but the adhesion is sufüciently firm. "The first change that 
takes place in the ovula after their application, consists of 
the outer or peripheriate tissue becoming more distinct and 
cellular; and in the production of a linear sub-irregular opa- 
que line in the centre of the ovulum and in the direction of 
its longest diameter, On submitting ovula in this state to 
pressure, the only means by which, owing to their extreme 
minuteness and softness, they can be analysed, they appear 
like vesicles filled with gelatinous fluid.
