Pilulas (pills) is 'in the accusative, object of the verb 

 recipe. Catharticas, compositas, and duas are adjectives, 

 agreeing with pilulas. We can only write this prescription 

 correctly, without using the accusative case, by abbreviating 

 it as follows : 



Pil. Cath. Co. u.

 trine aloes and sulphate of strychnine. The dose of reduced
