608 Abstract Report of Agricultural Discussions. 
The arica nut, when given to dogs and other animals suffering 
from the existence of tape-worms, is foimd to be a most powerful 
remedy. It should be administered in the form of powder to the 
extent of a di-achm : but generally a teaspoonful mixed with a little 
water is given to the dog fasting, and if there be a tape-worm in the 
intestines it will almost certainly be expelled in the com-se of a few 
hours. The arica nut is a remarkable anthelmintic, and it is not less 
remarkable that it had never, that he was aware of, been given to the 
human subject. 
Lord Bekneks observed that he had used the nut with great success 
as a remedy for common worms. 
Professor Simonds. — With regard to fowls and the existence of 
worms in their windpipes, the worm is not the filaria bronchialis 
— nor is it allied to that description of worm. It is termed syn~ 
gamus trachealis, and is believed to be the connecting link between 
the bi-sexual worm and those in which the sexes are separate and 
distinct. The worm very rarely exists in larger numbers than about 
two or three, though he had met with as many as seven in the 
windpipe of a chicken. It was a true bloodsucker. It fixes its 
head in the mucous membrane, and exhausts the power of the chicken 
by sucking its blood. This worm is met with in all the gallina- 
ceous tribes of birds, whether wild or domesticated. Hence it is often 
the cause of great loss in the rearing of pheasants and partridges. 
Great numbers of rooks are also killed by it ; but, singularly enough, 
aquatic birds, such as ducks and geese, may march about with perfect 
impunity amongst other birds affected with the syngamus. One 
means of getting rid of the worm is entirely mechanical ; that is, to 
pass a feather into the trachea and give it a sweep roimd. The worm 
attaches itself to the barbs of the feather, and is thus brought away. 
There is no occasion for dipping the feather into turpentine ; it is 
indeed only the more likely to kill the chicken. Under this treat- 
ment, however, many chickens are destroyed, and the best way of 
getting rid of the worm is by making the birds inhale a medicated air, 
and inducing them to take up little pellets of food mixed with assa- 
fcfitida and tui'pentine. Let a few grains of barley, for example, be 
steeped in tui'pcntine and thrown down with others to the poultry. 
The birds will then pick up the grains indiscriminately, and if they 
pick up the steeped grain with the others, the worm is got rid of. 
The fumes of tobacco are also an excellent remedy. Let the chickens 
be placed under a tub, propped up a little on one side ; then burn the 
tobacco on the outside, and let the di'aught carry the smoke under the 
tub. Do this, and, with the assistance of assafoetida pUls, you may 
soon destroy the syngamus trachealis.

The Tflcliina Spiralis. — A remarkable case of death arising from 
the effects of this entozoon occurred in January, 18G0, in the hospital 
of Dresden, in the person of a female farm servant bclougiug to the
