distinction is no longer suitable and the way instruments were called was a matter of local usage. The vernier-read instruments were called transits and more precise ones with optically read instruments were called theodolites. Earlier theodolites used to have verniers and micrometer microscopes for reading angles, then they were manufactured with optical systems with witch the user could read both horizontal and vertical angles through an eyepiece located near the telescope. The newest theodolites showed the horizontal and vertical angles digitally in a display window. Now, actually, transits and theodolites are almost obsolete in American surveying practice. The textbook author (textbook pages were in moodle) refers to transits as being the American-style instruments, they have four levelling screws and silver horizontal and vertical scales and they are usually equipped with plumb
However, he continued to reach for the microscope. I watched him, still staggered, as he examined the slide for an even shorter time than I had. "Prophase," he agreed, writing it neatly in the first space on our worksheet. He swiftly switched out the first slide for the second, and then glanced at it cursorily. "Anaphase," he murmured, writing it down as he spoke. I kept my voice indifferent. "May I?" He smirked and pushed the microscope to me. I looked through the eyepiece eagerly, only to be disappointed. Dang it, he was right. "Slide three?" I held out my hand without looking at him. He handed it to me; it seemed like he was being careful not to touch my skin again. I took the most fleeting look I could manage. "Interphase." I passed him the microscope before he could ask for it. He took a swift peek, and then wrote it down. I would have written it while he looked, but his clear, elegant script intimidated me. I
