Ernst Johannes Hartung was a chemist and astronomer. Educated at the University of Melbourne (BSc 1913, DSc 1919), he became lecturer in 1919, associate professor in 1924, and succeeded Rivett as chair of chemistry in 1928, remaining in this position until 1953. Hartung?s lecturing style surged with enthusiasm and he employed the use of screen projections to demonstrate chemical phenomena to large undergraduate classes. In 1935 he recorded Brownian movement in colloidal solutions on 35 mm cinefilm, which was later copied onto 16 mm film for the Eastman Kodak Co. World Science Library. This can be viewed in the Chemistry laboratory. He researched the photo decomposition of silver halides, and was awarded the David Syme Prize in 1926. He devoted time to the design and construction of a large, new chemistry building for the School of Chemistry (built 1938?1939). During World War II he was approached by Professor Thomas Laby, chairman of the Optical Munitions Panel, to chair the advisory committee on optical materials, to produce high quality optical glass in Australia. This was successful, with large-scale production achieved within ten months at a reasonable cost. Hartung served three terms as general President of the (Royal) Australian Chemical Institute, was an ex-officio councillor of the Council for Scientific and Industrial Research, and a Trustee of the Museum of Applied Science (now part of Museum Victoria).Set of analytic weights, used by E.J.H. in most of his work

The collection of thirteen model horse drawn vehicles were carefully handmade by Mr Chas W Davis 1925 - 2002. He was a talented artist and saw doctor. This model of a horse drawn Dairy Cart replicates the vehicle that enjoyed respect from the public during the 1880 and early 1900's. A model of a horse drawn black open Davis Dairy Buggy or Cart which is a lightweight two wheeled one passenger open horse drawn carriage where the driver sits behind. It has two large gold painted spoked wheels with black rims and mudguards, blue painted seating and gold painted armrests, two gold coach lamps and gold patterned footrest in front of the driver. At the rear are three silver milk cans with two taps to dispense the milk. There are two long brown wooden shafts on each side to surround the horse. It has a model of a brown coloured horse with a black tail and mane, which has the necessary horse tack for carriage use to help the driver communicate with the horse. These carrier carts or vans were two wheeled medium weight Commercial Vehicles.DAVIS DAIRY painted in white lettering on each side of the cart.replicas, models, scale models, vehicles, carriages, horse drawn vehicles, toy horses, early commercial vehicles, milk cart

The collection of thirteen model horse drawn vehicles were carefully handmade by Mr Chas W Davis 1925 - 2002. He was a talented artist and saw doctor. This model of a horse drawn Baker's Cart replicates the vehicle that enjoyed respect from the public during the 1880 and early 1900's. A model of a single horse drawn red enclosed Capital Bakery Cart which is a lightweight four wheeled one passenger horse drawn carriage where the driver sits behind. It has two large and two smaller gold painted spoked wheels with brown rims, grey and black painted seating two gold coach lamps and a sloped red and tan footrest for the driver. There is a brake lever on the right side of the cart which activates the brake on the back wheel. At the rear are two ventilated gold doors and cupboards underneath the seat. There are two silver metal tubular shafts on each side to surround the brown horse which has a black tail and mane. It has the necessary horse tack for cart use to help the driver communicate with the horse. These carrier carts or vans were four wheeled medium weight Commercial Vehicles which were a very familiar sight in the horse drawn era. Every kid 'whipped behind' bread carts. The first models were imported from England around 1870 and later the local coachworks built many models. The biggest producer was Flood in St Kilda Road until 1926.CAPITAL BAKERY is painted in white lettering on each side of the cart.replicas, models, scale models, vehicles, carriages, horse drawn vehicles, toy horses, early commercial vehicles, bread cart
