can no longer include the marsupialia as a whole under the name 
aplacentalia. 
Any person residing in the country desirous of helping Mr. 
Hill in his interesting and important investigations, would render 
material assistance by placing themselves in communication with 
him at the Biological Laboratory of the University of Sydney, 
with a view to arranging for securing specimens of opossums, 
native cats, bandicoots, or any other kind of marsupial. This 
important discovery by Mr. Hill was not the result of chance, but 
the outcome of patient and systematic research, a fact which still 
further enhances its merit, and this Socicty will not hesitate, I 
am confident, to offer their warm congratulations to Mr. Hill. 
Professor Haswell has during the past year been engaged more 
or less continuously in completing and seeing through the press 
the fine and well illustrated textbook on biology, which he has 
written in collaboration with Professor Parker of Dunedin. This 
important work is expected to be published in the next few 
months. He has also contributed afew notes on the structure of 
the nautilus. 
Chemical Laboratory.—Professor Liversidge’s recent researches 
such as those on the occurrence of gold in sea-water, the crystal- 
lization of gold etc., have already been published in our Proceed- 
ings. His demonstrator Mr. J. A. Schofield has collaborated 
with Mr. Smeeth and myself in our paper on the Antarctic rocks 
collected by Mr. C. E. Borchgrevink. 
Engineering Laboratory.—Owing to the absence of Professor 
Warren in Europe and America during a great portion of last 
year, little original work has been done, with the exception of 
testing concrete. The munificent bequest of Mr. P. N. Russell 
of £50,000 to the Engineering Department, promises a consider- 
able expansion of this School, and a widening of its field of use- 
fulness in the near future. 
Geological Laboratory.—Besides the paper above referred to, 
an important contribution to our knowledge of perlitic structure
