EELWORMS. 
In some instances the short brown deformed shoots had a little bit 
of deformed shoot or of leaf-growth proceeding from it. One of the 
shoots, which was merely swollen, not altogether shortened by disease, 
on being opened, proved hollow near the base, with decayed matter 
within, and also palish-brown powdery or rather damp granular 
matter; and, on placing this under an inch-power, it proved to be 
swarming with Anguillulidce. Under a quarter-inch I clearly dis¬ 
tinguished in some of these the presence of a spear with bulbous base. 
I also found Anguillulidce in the short, brown, somewhat bulbous-like 
shoots, in the perishing matter in the centre of the short somewhat 
scale-like leaves. 
On forwarding specimens to Dr. de Man for his skilled investigation, 
he replied:—“ I have examined the Clover plants that you have sent 
me, and most plants, if not all, were found to be infested by numerous 
Tylenchus devastatrix , so that the occurrence of this dangerous worm 
ought to be regarded as the cause of the disease.” 
Dr. Ritzema Bos also replied:—“ In the Clover-sick plants I have 
examined the deformations you so correctly describe, and I found 
T. devastatrix in them.” 
Dr. Bitzema Bos added the following information, which is well 
worth observation, as showing how plants completely different in 
kind, but all subject to attack of this kind of Eelworm, can both 
receive and convey the attack to each other :— 
“ I had sown some time ago Onions in sand, mixed respectively 
with Tulip-rooted Oats, Clover-sick plants, and Carnations, attacked 
by Tglenchi ; and I found that the Tylenchi of each of these diseased 
plants attacked the Onions, and made them diseased in the same 
manner as the Tylenchus disease with which we are acquainted in the 
Netherlands; and, in sand mixed with decaying Clover-sick plants 
and diseased Onions, I sowed Oats, and soon the Oats became Tulip- 
rooted. Thus I have shown that not only morphologically, but also 
physiologically, there is no specific difference between the Tylenchi in 
Clover-sick plants, in Tulip-rooted Oats, in ‘Pine-apple’ diseased 
Carnations,* and in diseased Onions.” 
* “Pine-apple” diseased Carnations.—This peculiar form of growth had been 
so marked in some specimens of diseased Carnations which I had recently forwarded 
to Dr. Bitzema Bos, that I had suggested this name as convenient for describing the 
appearance of Carnations attacked by T. devastatrix, just as the word “ Tulip-root ” 
is used to describe Oats with this outward manifestation of presence of this 
Eelworm. It may be of interest further on to mention that in my own experiments 
as to infestation I sowed Turnips over Tulip-rooted Oats, torn small and buried in 
the soil, into which the seedling Turnips presently shot; and, on submitting these 
to Dr. de Man, he found one Turnip was infested with the Tylenchus devastatrix, 
but I was not able to continue my experiments on account of being then removing 
to a new home.— Ed,
