As you contemplate studying this science and have asked to know the necessary studies, I wish to impress it upon your minds that you begin with anatomy, and you end with anatomy, a knowledge of anatomy is all you want or need, as it is all you can use or ever will use in your practice, although you may live one hundred years. You have asked for my opinion as the founder of the science. Yours is an honest question, and God being my judge I will give you just as honest an answer. As I have said, a knowledge of anatomy with its application covers every inch of ground that is necessary to qualify you to become a skillful and successful Osteopath, when you go forth into the world to combat diseases. WHAT I MEAN BY ANATOMY. I will now define what I mean by anatomy. I speak by comparison and tell you what belongs to the study of anatomy. I will take a chicken whose parts and habits all persons are familiar with to illustrate. The chicken has a head, a neck, a breast, a tail, two legs, two wings, two eyes, two ears, two feet, one gizzard, one crop, one set of bowels, one liver, and one heart. This chicken has a nervous system, a glandular system, a muscular system, a system of lungs and other parts and principles not necessary to speak of in detail. But I want to emphasize, they belong to the chicken, and it would not be a chicken without every part or principle. These must all be present and answer roll call or we do not have a complete chicken. Now I will try and give you the parts of anatomy and the books that pertain to the same. You want some standard author on descriptive anatomy in which you learn the form and places of all bones, the place and uses of ligaments, muscles and all that belong to the soft parts. Then from the descriptive anatomy you are conducted into the dissecting room, in which you receive demonstrations, and are shown all parts through which blood and other fluids are conducted. So far you see you are in anatomy. From the demonstrator you are conducted to another room or branch of anatomy called physiology, a knowledge of which no Osteopath can do without and be a success. In that room you are taught how the blood and other fluids of life are produced, and the channels through which this fluid is conducted to the heart and lungs for purity and other qualifying processes, previous to entering the heart for general circulation to nourish and sustain the whole human body. I want to insist and impress it upon your minds that this is as much a part of anatomy as a wing is a part of a chicken. From this room of anatomy you are conducted to the room of histology, in which the eye is aided by powerful microscopes and made acquainted with the smallest arteries of the human body, which in life are of the greatest known importance, remembering that in the room of histology you are still studying anatomy, and what that machinery can and does execute every day, hour, and minute of life. From the histological room you are
