Ixviii INTRODUCTION. » 



that the botanical tradition has given ther- 

 badge vulgaris or officinalis to the plant 

 The former term imports that the plant 

 had that name by common consent pre- 

 vious to the systematic arrangement, and 

 the latter imports that the plant was known 

 in drug-shops by that name. 



2. Constancy of association between 

 THE English and Latin Names. All the 

 examples of No. i apply here, and others 

 may be added : — J.65m^/mtm wormwood, 

 Allium garlic, Cicuta hemlock, Faba bean, 

 Fraga strawberry, Hedera ivy, Juncus 

 rush, Marruhiiim horehound, Millefolium 

 yarrow, Senecio groundsel. 



3. Continuity of English Name. In 

 some cases this is so perfect and unbroken 

 that it would be adequate evidence as proof 

 sole. But it is for the most part the same 

 instances upon which this and the fore- 

 going proofs converge, thus : — 



Acer, mapulder, maple tree. 

 Alba spina, hseg porn, hawthorn. 

 Betulus, byre, birch. 

 Corylus, hsesel, hazel. 

 Fraga, streowberige, strawberry.
