From Robert Chambers to William Kemp   4 April 1848

Dear Sir,

I should have sooner noticed and thanked you for your truly obliging communication of the 29th March, but for a wish to send at the same time a notice of the measurements being taken for me of the alluvial terraces at Crawford in Lanarkshire. These I have only this afternoon received, and I state them, that you may be enabled to compare them with the heights of other sea-markings. The other day, I began to think that there must be an inequality above 600 or 700 feet, for, after all, the regular survey of GlenRoy places everything 25 feet lower than I had made it, the lowest terraces being 847 and so forth. Now I begin to think there will be a final exhibition of uniformity nevertheless. Your letter promotes it materially. I shall now add the measurements given in a few cases:

Crawford — Eildon — Glenroy

1495

1362

1336 1337

1286 1282

1251 1261

1226

1204

1171 1172 1169$\frac{1}{2}$ corrigendum 1159$\frac{1}{2}$

1133 1139$\frac{1}{2}$

1107 1125

1090 1083 1089

1059

1023 1024

962 963 969$\frac{1}{2}$ 959

937

910 912

844 847

826

There is here a tolerable appearance of uniformity, but we cannot yet say it is decisive.

If anything else occurs to you, you will not fail to communicate them. I remain, | dear sir, | your obliged and faithful | R. Chambers.
