add that these variations nearly always present peculiar qualities also. We 

 ■will cite examples. 



"Upon a plant of black-fruited Muscat grape we have observed for several 

 years that some shoots produce white grapes. 



" The white seedless Corinth is a bud-variety from a variety which has 

 much larger fruits with se eds. This is a fact which we have several times 

 observed upon bunches where some fruits were unusually developed and 

 which contained seeds. The White Corinth is analagous to the Ghesselas de 

 Demoiselles. Like this, it is the result of a lack of fertilization of the 

 flowers. 



"A proprietor of large vineyards in the middle of France, the late Cazalis 

 Allut, wrote some years ago as follows : 



" 'A stock of Teret produced with me, for several years, black grapes upon 

 shoots of two of its arms, and grey grapes upon shoots of the other arms. 

 A stock of Epiran gris, trained in cordon, is now about forty feet long. The 

 first twenty feet produce constantly grey grapes and the remainder produces 

 white ones. I have in an enclosure a stock of Epiran noir having several 

 arms. The shoots of one of the arms give grapes almost twice as large as 

 those on other parts of the vine.' 



"Another viticulturist, M. Henri Bouschet of Montpellier, wrote very 

 recently: — 



" 'I have had occasion for several years to use in my collection at Lot-et- 

 Garonne, a plant of Prictiella gris, which, sometimes upon one stem, some- 

 times upon two, bore black grapes, while the remainder of the vine bore 

 grey ones. I have noticed for two years in my collection at Calmelte a most 

 curious fact upon three grafts of a Spanish variety which came to me from 

 the collection of Luxembourg, where it is called Parrel del Regno de Lorca 

 and which I have recognized as our Morastel noir. One of these three stocks 

 has borne on one side, to my great surprise, black grapes exactly similar to 

 those of the Morastel, and upon the other side, constantly, white bunches 

 having an appearance very different from an ordinary white Morastel, and 

 presenting a foliage very different in size and form. This odd foliage appears 

 to me to be identical with that of the Oyo de Rey de Morada, of which the 

 leaves, bright yellowish-green, present very shallow rounded dentate lobes, 

 while the leaves of the Morastel are deep green with deep divisions, the lobes 

 acute, with teeth detached and terminating in a point.' 



" A passage which we find in the Parfait Vigneron (edition of 1811) 

 seems to confirm entirely the opinions which we give concerning bud-varia- 

 tions in grapes: — 



" ' A citizen of Vilmorin has observed a stock of Meunier to bear, upon 

 some shoots, leaves and fruits of Maurillon lirecoce. A citizen of Jumilhac 

 has seen likewise the Meunier become Maurillon.^ 



"Therefore the grape called Madeleine, Juillet, Maurillon hdtif, etc., is 

 only an accident from Meunier, a fact which shows, as we have said before, 

 that the varieties produced by bud-variation can present qualities different 

 from those presented by the plants from which they come. 



" Upon a plant of Pinot gris there appeared at the museum in 1863 a 

 shoot whose leaves were much variegated or striped with yellow. It produced 

 a grape very similar to the variety from which it came. It appeared to be 

 much less fertile, however. 



" In 1863 we observed two other very remarkable examples. One example 

 refers to the Precoce Malingre, the other to the variety designated by the
