“ Tulip-root ” accompanying, well confirms the observations of Barley 
not being liable to this kind of infestation ;— 
“ There is a large area of the Oat-crops on our Wiltshire hills 
which have failed in different parts of the fields so cropped. I have a 
field sown with a mixture of Oats and Barley, which we call ‘Dredge.’ 
I noticed that the Barley was good, and the Oats almost a failure. I 
told my bailiff to ascertain the cause ; yesterday he brought me what 
I herewith send you.” 
Besides the above, specimens of Eelworm-infested Oats were sent 
me from two localities, with much more of the reedy or sedgy form, to 
which the word “ segging ” or sedging is applied, than the peculiar 
“ Tulip-root ” swelling. 
Specimens of Black Oats were sent me from Sapcote Fields, near 
Hinckley (on the edge of Leicester- and Warwick-shires), by Mr. W. 
Nurse, with the following note :— 
“ They are grown upon a black soil (bog); some of the Oats are 
looking well and are in ear, and others are as the sample I have 
enclosed. Last year they went the same upon the same piece of land ; 
I thought then it was from the dryness of the season.” 
These Oat-plants were about six or seven inches high in the 
leafage, andhnostly of a deep green colour, although some of the shoots 
were yellowish. The shoots were thin and rushy looking (sometimes 
about six to a root),—not “ Tulip-rooted,” but having just a small 
quantity of wrinkled shoots round the base. 
On July 5th, Mr. Geo. L. Purchase wrote to me, from Chichester, 
regarding injury to Oat-plants in the district, and a few days later 
forwarded specimens and the following note :— 
“ The attack is very general in this district among spring-sown 
Oats. Autumn-sown Oats are not attacked. Those sown in April are 
the worst ; those sown earlier are not so bad. In a case of Barley 
sown with Oats, the Barley is not attacked.” 
In this instance, as well as the preceding one, the plants were much 
more rushy than “ Tulip-rooted ” in appearance, and with very little 
of the pale yellow doubled and crinkled shoots round the base of the 
stem which often, or usually, are found round the swollen “ Tulip- 
rooted ” base. I therefore, as Dr. J. G. de Man, of Middleburg,— 
who is one of the leading authorities on Anguillulida ,—was then in 
England, submitted specimens to him, in order to be certain that the 
attack was caused by the same kind of Eelworm, namely, the 
Tylenchus dexastatrix ,—and such proved to be the case. 
Cephalobus rigidus, Schneider.—The following observations refer to 
Eelworm attack found in Oat-plants grown near Milford Haven, in which 
the plants were found to be infested not by the common “ Tulip-root ”
