Graham Bell filed a specification and drawings of the 
original Bell telephone. 
Professor Asa Gray, writing of what is generally 
called Metamorphosis of Plants, says: ‘The adopted 
theory supposes that stamens and pistils, as well as 
sepals and petals, are homologous with leaves; that the 
sepals are comparatively little, the petals more, and the 
reproductive organs much modified from the type, that 
is, from the leaf of vegetation. This is simply what is 
meant by the proposition that all these organs are 
transformed or metamorphosed leaves. What would 
have been leaves, if the development had gone on as a 
vegetative branch, have in the blossom developed in 
other forms, adapted to other functions. Linnzeus ex- 
pressed this idea, along with other more speculative 
conceptions, dimly apprehended, by the phrase Vege- 
table Metamorphosis. Not long afterwards, this fecund 
idea of a common type, the leaf, of which the parts of 
the flower were regarded as modifications, was more 
clearly and differently developed by a philosophical 
physiologist, Caspar Frederic Wolff. Thirty years later 
it was again and wholly independently developed by 
Geethe, in a long-neglected but now well-known essay 
on the Metamorphoses of Plants. Twenty-three years 
afterwards, similar ideas were again independently pro- 
pounded by DeCandolle, from a different theoretical 
point of view.”
