(6) The proportion of the length of the lower limb to the height of the body, taking the latter as 100. The range of these 27 indices is 46·9 to 51·6. Two-thirds of the total number are included between 48 and 50; and since the average of the numbers, which is 49·1, corresponds nearly with the value of the middle index of the series, we may take it as representing the proportion that the lower limb usually bears to the height of the body amongst these natives.
| Indices. | Number of Measurements. |
|---|---|
| 46·9 | 1 |
| 47-48 | 4 |
| 48-49 | 8 |
| 49-50 | 10 |
| 50-51 | 3 |
| 51·6 | 1 |
| Total, 27 | |
(7) The span of the outstretched arms.—The following indices—69 in all—show the ratio of the span of the arms to the height of the body, taking the latter as 100:—
| Indices. | Number of Measurements. |
|---|---|
| 100-100 | 1 |
| 101-102 | 4 |
| 102-103 | 2 |
| 103-104 | 4 |
| 104-105 | 5 |
| 105-106 | 5 |
| 106-107 | 18 |
| 107-108 | 11 |
| 108-109 | 6 |
| 109-110 | 9 |
| 110-111 | 3 |
| 112·6 | 1 |
| Total, 69 | |
The range of these indices is 100 to 112·6; and the indices of greatest frequency are those included between 106 and 107. Placing all the indices in their order, I find that the value of the central of the series is 106·7, and of the quarter-points 105·2 and 108·6 respectively. Taking 106·7 as representing the average proportion which the span of the arms bears to the stature amongst these natives, I may compare it with similar results given for other races in Topinard’s Anthropology:—
| American soldiers (10,876), | 104·3 |
| Solomon Islanders (69), | 106·7 |
| Negroes (2020), | 108·1 |
(8) Distance of the tip of the middle finger from the upper edge of the patella.
| Distance. | Number of Measurements. | ||||
|---|---|---|---|---|---|
| 2 | inches. | 2 | |||
| 2 | to | 3 | „ | 6 | |
| 3 | to | 4 | „ | 11 | (9 of these at 31⁄2 inches). |
| 4 | to | 5 | „ | 2 | |
| Total, 21 | |||||
From this table it will be seen that amongst 21 natives the tip of the finger never approached the patella nearer than two inches, and was never farther removed than five inches. The value of greatest frequency is 31⁄2 inches, and it may be taken as approximating to the average distance. Comparing it with the average stature (64 inches) taken as 100, we obtain the index 5·46; but by comparing the distance of the middle finger above the patella with the stature as 100 in each individual measurement, we obtain a more reliable average index somewhat smaller than the preceding.
