unlikeness gives us the idea of the genus or species. 

 The greatest measure of unlikeness forms the 

 genus, the less the species ; still less, the variety

 twisted, hanging down and exceedmg much the

 years ago the foreman of Messrs. Vtitch raised a

A New Fungus on the Pea. — In a recent ad-

A-side from this bit of illustrative natural history, 

 the plant has charms for flower lovers. We can- 

 not do better under this head than^quote what the 

 introducers tell us about it : 



in the production of which insects play no part. 

 It appears to have the effect of stunting the growth 

 of the plants and lessening the crop.
