The Word "Alarm"

I send you an instance of the accurate use of the word "alarm" which may be interesting. In an account of the attempt made on the 29th of Oct. 1795, to assassinate Geo. III., the Earl of Onslow (as cited in Maunder's *Universal Biog.* p. 321.) uses the following expression:— "His Majesty showed, and, I am persuaded, felt, no alarm; much less did he fear." Is not this a good instance of the true difference of meaning in these two words, which are now loosely used as if strictly synonymous?
