bryonal booklets in any other human Taenia : the 

 central ones resemble stilettoes. The inner booklets 

 were 0-0069 to 0-0071 mil. in length; the outer ones, 

 0.0046 mil. The calcareous corpuscles were as large 

 and numerous as in T. mediocanellata. 



" This Tsenia is particularly rich in cholesterine ; 

 for very large flakes of this substance made their 

 appearance in the deposit which I obtained from the 

 sediment at the bottom of the bottle in which this 

 tapeworm came from the Cape."

 the flesh of pigs, as Hottentots (from one of whom the

 small, seldom exceeding three mil., and possessing a 

 circlet of hooks, 28 to 36 in number. It usually has 

 but three or four articulations, the last of which is the 

 mature segment, fecundated and charged with eggs. 

 The sexual organs are lateral, the penis being found 

 a little below the centre of the segment. The ovaries
