-t from pet, and the result is pe — ^just as long or just as short 

 in one case as the other. 



The same power of accenting the first syllable is " particularly 

 the case in those words in which the vowel i can assume the 

 power of y. Latin scholars are divided as to the proper ac- 

 centuation of mulieres, Tulliola, and others : though custom is 

 in favour of muli'eres, mul'ieres appears to be more correct." Be 

 it so. Let mulieres be midyercs. AYhat becomes, however, of 

 the fourth syllable ? The word is no quadrisyllable at all. What 

 is meant is this : — not that certain quadrisyllables with two 

 short vowels in the middle are difficult to accentuate, but that 

 they are certain words of which it is difficult to say whether 

 they are trisyllables or quadrisyllables. 



For all practical purposes, however, words like Cassiope are 

 quadrisyllables. They are, in the way of metre, choriambics ; 

 and a choriambic is a quadrisyllable foot. They were pro- 

 nounced Cassiope, &c., by English writers of Latin verses — 

 when Latin verses were written well. 



Let the pronunciation which was good enough for Vincent 

 Bourne and the contributors to the Musse Etonenses be good 

 enough for the entomologists, and all that they will then have 

 to do is not to pronounce cratcegimi like stratagem, cardamines 

 like Theramenes, and vice versa. Against this, accent will ensure 

 them — accent single-handed and without any sign of quantity — 

 Cardamines, Theramenes, cratch gum, stratagem.
