THE AUSTRALASIAN JOURNAL OF PHARMACY. 
will yield about 120 drops. The subject of tbe incompatibility of drugs was 
then exhaustively dealt with under the heads of chemical, pharmaceutical, and 
physiological incompatibility. A number of important points in connection with 
the incompatibility of drugs were fully gone into, the conclusion of the subject 
dealing with the laws of chemical incompatibility, &c., being left over for con- 
sideration at the next lecture. 
It was announced that, in consequence of the cordial support given by the 
students — some twenty having already been enrolled for the course of lectures, 
and a similar number for the courses in practical pharmacy and chemistry— it 
had been decided to grant certificates of attendance as regards the lectures, 
and similar certificates for the practical classes. At the end of the session an 
examination would be held in each branch, and standard works in chemistry, 
pharmacology, &c., would be awarded thereon. At the conclusion of the lecture 
the classes in practical pharmacy and chemistry met in the new laboratory, 
which is now in a fair way towards completion, as is also the materia medica 
museum. 
A cablegram from London announces that Mr. Frederick W. Ilall, second 
son of Mr. Frederick Hall, of Waverley, has passed the examination and taken 
first prize at Guy’s Hospital for medical students in their first year. It may 
be remembered that last year, after passing the London University Preliminary 
Science Examination with honours, Mr. Hall carried off the Open Entrance 
Science Scholarship for 125 guineas. 
The usual monthly meeting of the Horticultural Society of Hew South Wales 
was held in the Technical College Hall, Pitt-street, on Tuesday evening, 13th 
July. Mr. H. C. L. Anderson, M.A., presided, and there was a large attendance 
of members and the general public. According to invitation, a large number 
of plants, flowers, and other objects of horticultural interest were exhibited by 
members and others, the collection being a very fine one. Mr. F. Turner read 
a most instructive paper on “Economic Plants.” The paper was illustrated by 
various exhibits, amongst which were the famous Venezuelan rain tree (petlier- 
colobium saman), respecting the cultivation of which in this colony so much has 
been said of late, although experience teaches that it does not succeed further 
south than the 20th parallel of south latitude ; seeds of Duboisia Hopwoodii (pitury 
of the natives), the leaves of which are used by the aborigines of Central Australia 
to poison emus, and are chewed by them as is tobacco by some Europeans ; the seeds 
of Trapa Becornis (a floating aquatic plant), used by the Chinese as an article of food 
under the name of “ling;” a fruit of cegle marmelos (called “bhel”), which, 
when ripe, has an exquisite flavour and perfume, and from the rind of which a 
fine yellow dye is prepared; a fruit of Adamsonia Gregorii, the cream of tartar 
tree, collected in the Kimberley district (the pulp of its fruit consisting of gum, 
starch, sugary matter, and mallic acid, lias an agreeable acid taste, and is 
peculiarly refreshing in sultry climates) ; the seeds of Abrus precatorius, which 
are employed in India as a standard weight (the weight of the famous Koh-i-noor 
diamond was ascertained in this way), and the roots of which are used much in 
the same way as we use liquorice root ; a seed yielding a kind of vegetable ivory, 
the produce of a South Sea Island palm, called Sagus amicarum ; and a fruit of 
Hovenia dulcis (the Chinese raisin), exhibited by Mr. Lindley. The paper, 
which evinced a considerable amount of horticultural knowledge, acquired by 
long study, was listened to throughout with marked attention, and at its close 
a hearty vote of thanks was accorded Mr. Turner, on the motion of Mr. L. 
Wooff, seconded by Mr. E. Mortimore, who both bore high testimony to the 
benefit they had derived from the reading of the paper, as did also Mr. J. H. 
Beatson. The chairman (Mr. Anderson), in tendering the vote of thanks to Mr.
