this tree are poisonous, and contain prussic acid, if anyone doubts let 
them crush a little bark, the smell is nearly as strong as laurel, it 
generally follows in similar cases that the fruit or rather the seed, or 
kernel, exclusive of pulp, contains the poison in a concentrated form, 
hence we may take it that mountain-ash berries are poisonous from a 
chemical definition point of view. 
The Petty and other Spurges ( Euphorbia peplus, K. heliascopia and 
K. atnygdalaides) have all been eaten by children, and in some cases 
death has ensued. 
Lords and Ladies Arum {Arum maculatum), the commonest of 
hedgerow plants. Flowers, leaves and berries have all been eaten by 
children, several fatal cases are recorded. Amongst the plants which 
we have before mentioned, which have also unfortunately poisoned 
children are Wood Sorrel (Oxalis acetasa), Cicuta cirosa, Oenanthi‘ 
crocata, Datura stramonium and Siam latifnlium. Only this last 
summer we saw a boy of about six with a flower stem of this plant in 
his mouth, we of course made him discard it, and frightened his 
companions well. In conclusion it might not be out of place to 
mention a few noxious plants to be barred, which might cause illness 
or death, if they have not already done so. It should be understood 
that the plants we have mentioned are some of our worst examples, 
but in a paper like this, it is impossible to give every plant. 
Plants to be avoided. 
The Crowfoot family, except It. auricomus. The juices and 
bruised leaves of It. sceleratus, It. bulbosus and It. arris contain 
irritant properties, the leaves of 11 . arris will blister the hand 
if crushed. The Anemone {A. nemarasa, A. pulsatilla, A. pratensis, &c.), 
possess poisonous properties. The Wild Clematis or Traveller’s Joy 
{('lematis ritalba) is more or less poisonous. The Marsh Marigold 
(C alt ha palustris) may in certain localities contain poisonous qualities, 
but in this country they are of a mild character. The Yellow Stoneerop 
{Snlum acre) contains in its fleshy succulent leaves irritant properties. 
The Meadow Rue ( Thalirtrum durum) is certainly poisonous, so is the 
Purging Flax {L-inum cathartieum), which should never be taken by 
people who are not properly acquainted with its properties. The 
Horseradish {<' ochlearia armoracea) contains irritant properties, and 
Wild Celery (Apium >/rain dens) is more or less poisonous, the blanching 
in cultivation deprives the plant of its injurious properties. The Wood 
Sanicle (Sanicula eurapaca) contains similar properties. The Wild 
Lettuce (Lactuca virosa) contains highly dangerous qualities. The 
Bindweed (('anralrulus sepium) contains in its roots and leaves a 
poisonous principle. The P>luebell {Hyacinthus nonscriptus) contains 
noxious properties, as do the Lent Lily {Narcissus pseudo-narcissus) and 
the numerous cultivated varieties. Delphinium or Larkspur, of 
various species, are decidedly dangerous. The Cyclamen {Cyclamen 
europarum), the Fritillary or Crown Imperial {Fritillaria imperialis), 
common in all old fashioned gardens is bad. The Plumbago {Plumbago 
eurapaca) generally seen in greenhouses, has dangerous properties. The 
Rhododendron {It. chrysanthemum) is well known for its poisonous 
properties. Lobelia is another dangerous genus. The Soapwort 
(Saponaria officinalis), a common garden plant, Pink Root (Spiyelia 
marylandica and S. calif arnica) are both poisonous. The Meadow
