To you, my dear Sir, whom I have known for so long a period, and whose kind and unbroken friendship I have enjoyed for many years, I have much pleasure in dedicating this little work as a token of my esteem and regard, having the fullest confidence, from the homefeeling which I know you possess, that its contents will meet your approval.

Yours, faithfully,

HENRY HEAVISIDES.
