Mr.Sapsea (by a very remarkable coincidence) is of exactly that opinion.
Mr.Jasper is in beautiful voice this day.

In the pathetic supplication to have his heart inclined to keep this law, he quite astonishes his fellows by his melodious power.

He has never sung difficult music with such skill and harmony, as in this day's Anthem.

His nervous temperament is occasionally prone to take difficult music a little too quickly; to-day, his time is perfect.
These results are probably attained through a grand composure of the spirits.

The mere mechanism of his throat is a little tender, for he wears, both with his singing-robe and with his ordinary dress, a large black scarf of strong close-woven silk, slung loosely round his neck.
But his composure is so noticeable, that Mr.Crisparkle speaks of it as they come out from Vespers.
'I must thank you, Jasper, for the pleasure with which I have heard you to-day.
