Description

In eye dissections it is unnecessary to have either a large equipment of instruments or a special room. To have a laboratory at one’s disposal is but a small added convenience. Not to have it, is no serious hindrance. The work may be carried on and successfully done in one’s office or in the home, as well as in class-room or laboratory. If it is true that the atmosphere of a laboratory adds zeal to the efforts of a worker, but there is no laboratory available, then reverse the order; let the zeal of the worker add to the atmosphere of the place in which he is doing his work.

Two things, among others to be mentioned later, are essential; a table of convenient height, and a good light, natural or artificial. Both are but modest needs. Compared with other dissections, there will be found an absence of offensive odors. Neither are there any repulsive sensations experienced. Such experiences are quite common when making other kinds of dissections. This work is clean and attractive. Indeed, one may even develop a rather keen sense of the æsthetic. Many of the various parts of the eye, when separated and properly preserved, then viewed and inspected, are bound to bring forth exclamations of appreciation and wonderment. One can then better understand the statement: “When Nature perfected the first eye she took a day off so she could admire the result of her finest piece of handiwork.”

This does not imply that dissections of the eye tend to develop art appreciation. Appreciation of the wonderful in Nature’s construction of the special organs is not, however, to be relegated to a distant point. Such appreciation is concomitant with the knowledge that comes from having seen, handled, and examined the object studied.

The orchestra leader must have a good listening and hearing ear. This is developed in him because he has to exercise constantly his power of listening and hearing. The dissector who would become proficient in eye dissections and in anatomical investigations must have a good seeing eye and a dextrous hand. To acquire these two most valuable aids necessary to carry on careful inquiry or research, it is essential to practise using the eye and the hand. Combined with the expertness of these two, must be the ability to continue one’s efforts in the face of failure; to redouble one’s efforts to attain success despite the shortcomings of eye or hand. This simply means practise and patience. And the one who is without that wonderful virtue, patience, will never stay long enough with his problem to gain either an observing eye or an expert hand, or to achieve his end, and thereby reap the full and pleasing results of his efforts. In order of importance, patience really precedes dexterity, skill, and observation; and persistence of effort is a factor not to be entirely outshone by any other virtue. With these attributes, knowledge of the subject in hand naturally follows.

One reason why eye dissections are easily carried on is because material can always be readily procured. Any butcher will furnish sheep, pig, or beef eyes. Or, if one has the time to visit the manager of a slaughter-house, and make known to him one’s needs, he will supply enough eyes to carry through a host of interesting dissections and experiments, and give sufficient material for careful, orderly, and fruitful study. Perhaps in no other kinds of dissections will the investigator find so much of interest, or have his efforts crowned with such abundant and satisfactory results, as in the dissections of the eye. But no one should try to study all parts of the eye with only one specimen. To try to do so is an error, and a common one often committed by both teachers and students. Specimens cost little or nothing, and it is no more trouble to prepare a half-dozen eyes for dissection than one. The cost of preparation, too, is but little more for a number of eyes than it is for one, and may be no more in some instances. Besides, having enough material on hand saves time in case of a failure. Also, one can quickly repeat a dissection, and so procure any number of desired specimens of specific parts, or do over again the same dissection on another eye just for the purpose of practise, and thus add to one’s dexterity. It is, therefore, strongly advocated to have plenty of material on hand before beginning work. Economy here is not even “penny wise.”
