. The balls varied in size in the beginning depending upon how large the pig's bladder was.
Around 1862, Richard Lindon was desperate to find a replacement for the pig’s bladder and used an India rubber bladder instead. India rubber was too tough to inflate by mouth and so having been inspired by air syringes, he created a large brass air pump to inflate his rugby balls.
[The history of the rugby ball]
by Paul Wassell, 15 Oct 2016 Lindon also claimed to invent the rugby ball and its distinctive oval shape but didn't patent his design for either the ball, the bladder or the pump. By the 1880s there were several manufacturers of 'footballs' in England all using the same process.

The size and shape of the ball was not written into the rules until 1892, when it was determined as follows:][
- Length 11 to 11 1/4 inches
- Circumference (end on) 30 to 31 inches
- Circumference (in width) 25 1/2 to 26 inches
- Weight: 12 to 13 ounces
- Hand sewn with not less than 8 stitches to the inch
In 1892 the RFU endorsed ovalness as the compulsory shape. The gradual flattening of the ball continued over the years.][Blood, mud and aftershave](_blank)

The introduction of synthetic footballs over the traditional leather balls, in both rugby codes, was originally governed by weather conditions. If the playing surface was wet, the synthetic ball was used, as it didn't absorb water and become heavy. Eventually, the leather balls were phased out completely. Polyester is used as backing material to hold the ball's oval shape, along with additional material for grips to enhance performance. The ball is stitched with polyester thread and coated with wax to make it more water-resistant.
