Chapter 147

at the house of another person, it is considered vulgar to put "at Mr. So-and-So's," but simply "Mr. So-and-So's," _at_ being understood.

iii. It is more respectful to write the word "Esquire" in full. The ----substituted for initials is vulgar, and pardonable only in extreme cases; if the Christian name or initials of your correspondent do not occur to you at the moment, endeavour to ascertain them by inquiry.

iv. When addressing a gentleman with the prefix "Mr.," the Christian name or initials should always follow, being more polite, as well as avoiding confusion where persons of the same surname may reside in one house.
