Plerumque cummes naturales extrahuntur ex arbore, cui nomen est Hevea brasiliensis. Cum cortex arboris secatur, ex ea umor albus latex appellatus manat. Latex collectus ad cummim faciendam adhibetur. Physici modos inter primum bellum mundanum invenerunt quibus cummi artificiosum creetur: ex oleo enim et carbone fit. Hodie duae fere partes omnium cummium artificiosae sunt.
