1880. ‘“‘ Results of experiments on the transverse strength of 
the wood of £. glodulus,” by Baron von Mueller and J. G. 
Luehmann. 
“Results of experiments on the transverse strength of the 
wood of various Eucalypts,” by the same. 
Both these tables are published in a Catalogue of Timbers of 
Victoria in the Technological Museum of Melbourne, by Baron 
Mueller. They were originally published in the Sixth Decade of 
the learned Baron’s Lucalyptographia under E. glodulus. 
The experiments were performed on pieces of two inches 
square, and two feet long between the supports, the weight sus- 
pended in the middle, both ends free. The £. globulus timber 
was seasoned for nine months; similar information is not given in 
regard to the other timbers. 
1884. ‘Official Report of the Carriage Timber Board, 
” This Board was appointed, 
on a motion in the Victorian Parliament, with the view of 
ascertaining, by various experiments, the best kind of timber 
Victorian Railways, Melbourne, 1884. 
grown in the Australian colonies adapted for the construction of 
railway vehicles. 
The timbers received were seasoned for a year, and tests of 
them were conducted at the railway workshops at Newport, near 
Melbourne, from January to April, 1884. The mode of testing 
the various specimens was as follows :— 
‘‘ Two standards, six feet apart, were erected to form bearings 
for the specimens, which were seven feet long, and one seven- 
eighth of an inch square. Weight was applied at the centre, where a 
measure was adjusted to show, in inches and parts, the exact 
deflection at, and before breakage. Three specimens of each 
contribution were tested, and the mean result recorded.” 
1886. ‘The strength and elasticity of Ironbark timber as 
applied to works of construction,’ by Prof. Warren. (See Proc. 
R.S., N.S.W., 1886.) In this paper Prof. Warren (besides the 
experiments performed by himself) alludes to two experiments on 
the transverse strength of beams of Ironbark not referred to above. 
1887. “ The strength and elasticity of New South Wales 
timbers of commercial value,” by Prof. W. H. Warren, M.I.C.E.
