Trying to trace a poem I heard as a child it began with

Arithmatic just makes me sick cried our poor little Mary, the figures never act the same they're always so contrary.
That night when Mary fell asleep,
a dream so wonderous came, that afterwards arithmatic was never quite the same.

Quite suddenly a funny man was standing by her side "arithmatic has made you sick,just take this pill" he cried,
He held out such a great big pill she screamed out "never never " but down it went and then he said you're just as well as ever"

Unfortunatly I have no idea who wrote it I'm afraid, can anyone help? Thankyou
