GENERAL OBSERVATIONS

There are many other signs and abbreviations used in works on the various sciences. Approved modern text-books are the only safe guides to the proper use of these.

In printing dialect, slang, and colloquialisms the only general rule is to follow copy.

Such abbreviations as I've, you'll, 't'was, 't'is n't, and the like are more clearly expressed when a thin space is put between the words.
