FORMATION OF GENITIVE CASE

There are a few exceptions. Asdepias, gen. Asclepiadis ; Mas, 

 gen. Maris; Phosphis, 8ulphis, etc., gen. itis; Mucilago, gen. Mucil- 

 aginis; Solidago, gen. Bolidaginis, etc. 



The following words do not change in their genitive : ^ Amyl, 

 Azedarachj Berberis, Buchu, Cajuputi, Cannabis, Catechu, Condu- 

 rango, Cornus, Curare, Cusso, Fructus, Digitalis, Hydrastis, Jabo- 

 randi. Kino, Matico, Quercus, Sassafras, Sago, Sinapis, Spiritus, 

 Gambir, Sumbul. 



It is only necessary to use the accusative of the nouns express- 

 ing the ingredients, when the quantity is omitted, and a numeral 

 adjective takes its place. As before stated, the use of the appro- 

 priate symbols renders it unnecessary, as a rule, to write out in the 

 accusative the words expressing quantity. The following simple 

 rules for the formation of the accusative of these words are 

 appended : 



I. JSTouns expressing quantity ending in a, are feminine and 

 make the accusative singular in am and the plural in as. Example, 

 Drachma, ace. sing. Drachman, pi. Drachmas. 



II. Those ending in um or us make the accusative singular in 

 MOT. The accusative plural of those in us is os, and of those in um is 

 a. Those in us are masculine, those in um are neuter. 



Congius, ace. sing. Congium, ace. pi. Congios 

 Granum, ace. sing. Granum, ace. pi. Grana. 



The adjectives are declined like the nouns. The numeral cardi- 

 nal adjectives are indeclinable except unus, duo and tres. 

 They are thus declined :
