This bottle from a home in Bendigo is marked STOCKERS FIFTH PATENT" "SPECIAL FEEDING BOTTLE LONDON". On base "…IN FRANCE". It may have originally been fitted with a teat and a long uncleanable India rubber tube.
Glass bottles in the 1860s and 1870s used glass and rubber tubes to improve the flow of food and to connect the teat to the bottle. However, despite often coming with a special cleaning brush, the tubes were a source of bacterial growth, and ‘siphonia’, and ‘Alexandra’ bottles became known as ‘killer’ or ‘murder’ bottles. However, they continued to be popular, as it wasn’t understood that germs could be invisible, and because the bottle itself could be conveniently placed in the cot with the baby, who could then feed from it all day.
