The proprietor gives an address in the south of England, and the prices charged are 1s. 1½d. and 2s. 9d. a box; the 2s. 9d. box contained 48 powders.
They were described in a circular enclosed with the box as:
The best medicine for infants cutting their teeth, preventing convulsions, thrush, disordered bowels, and for all the feverish diseases of infants and children.
The following directions are given:
For an Infant under three years of age, give one of Fenning’s Cooling Powders mixed with a little water, or it could be thrown dry as it is into the opened mouth of the baby, and gently holding back the head for half a minute it would be swallowed.
Whenever an Infant is restless or feverishly hot from Teething, when it is griped or sick from improper food, or over-feeding; has acidity, or a disordered stomach, one of these Powders should be immediately given and, if necessary, repeated every day....
When a Child is attacked with Thrush, Measles, Hooping Cough, or Fever of any sort, always keep the feverish blood cool by giving a dose of Fenning’s Cooling Powders every or every other day.
The powders had an average weight of 3·4 grains; twelve powders weighed singly had weights varying from 3·2 to 3·8 grains. Analysis showed the powder to consist of:
| Potassium chlorate | 70 | per cent. |
| Powdered liquorice | 30 | ” |
The estimated cost of the ingredients of the powders in a 2s. 9d. box is one-sixth of a penny.
