doses it acts as an emeto-cathartic. It retains its properties 
for a considerable period, if prepared in the following man- 
• ner:— to every two ounces of the gum add an ounce of boiling 
water, stir well, and mix with half an ounce of strong rum, 
strain and keep in a well closed bottle. The dose is a tea- 
spoonful. 
Ionidium Marcucci. — In the last volume of this journal we 
gave a short notice of this plant, since which we have been 
favoured by Dr. Hulings with dried specimens, a drawing of 
the plant, the report made to the Colombian government 
on the subject, and also with the description published to aid 
the search for it. As every thing relating to this plant is of 
importance, if on further trial it should be found to fulfil the 
high powers attributed to it, we have also inserted a memoir 
by Dr. Bancroft, which gives a condensed view of all that 
is known respecting it. 
In this paper, as before mentioned, he considers the plant 
to be a new species differing from the I. parviflora, and the 
drawing in our possession agrees perfectly with his descrip- 
tion, as do the specimens received from Dr. Mutter, and one 
of those from Dr. Hulings, labelled as coming from Riobam- 
ba, where Mr. Marcucci obtained it. On the other hand, the 
official description referred to, terms it I. parviflora, and de- 
scribes that plant, added to which most of the specimens ac- 
companying it, are certainly different from the plant of Dr. 
Bancroft, being fruticose and not procumbent, with smooth 
peduncles, — thus agreeing with the I. parviflora. 
It is, however, highly probable that they are possessed of 
identical properties, as it is well known that the roots of all 
the species of this genus are emeto-cathartic in an eminent de- 
gree, and produce precisely the train of symptoms attributed 
to the Cuichunchilli. 
Coulteria Tinctoria. — According to Dr. Macfadyen, 
{Jamaica Phys. Journ., April, 1834,) this plant, which is a 
native of several parts of South America, has been introduced
