The prototype of punctuation. It is observed by Garvinus that the systems of punctuation in use by the various literary nations depended originally upon the social habits and general diet of the flies infesting the several countries. These creatures, which have always been distinguished for a neighborly and companionable familiarity with authors, liberally or niggardly embellish the manuscripts in process of growth under the pen, according to their bodily habit, bringing out the sense of the work by a species of interpretation superior to, and independent of, the writer's powers. The "old masters" of literature - that is to say, the early writers whose work is so esteemed by later scribes and critics in the same language - never punctuated at all, but worked right along free-handed, without that abruption of the thought which comes from the use of points. (We observe the same thing in children to-day, whose usage in this particular is a striking and beautiful instance of the law that the infancy of individuals reproduces the methods and stages of development characterizing the infancy of races.) In the work of these primitive scribes all the punctuation is found, by the modern investigator with his optical instruments and chemical tests, to have been inserted by the writers' ingenious and serviceable collaborator, the common house-fly - Musca maledicta. In transcribing these ancient MSS, for the purpose of either making the work their own or preserving what they naturally regard as divine revelations, later writers reverently and accurately copy whatever marks they find upon the papyrus or parchment, to the unspeakable enhancement of the lucidity of the thought and value of the work. Writers contemporary with the copyists naturally avail themselves of the obvious advantages of these marks in their own work, and with such assistance as the flies of their own household may be willing to grant, frequently rival and sometimes surpass the older compositions, in respect at least of punctuation, which is no small glory. Fully to understand the important services that flies perform to literature it is only necessary to lay a page of some popular novelist alongside a saucer of cream-and-molasses in a sunny room and observe "how the wit brightens and the style refines" in accurate proportion to the duration of exposure.
