The daily number of sunspot groups on the solar disk, as recorded by the programme of sunspot observations performed under the aegis of the Royal Observatory, Greenwich, UK, and subsequently the Royal Greenwich Observatory (RGO), is re-examined for the interval 1874 -1885. The motivation for this re-examination is the key role that the RGO number of sunspot groups plays in the calculation of Group Sunspot Numbers (Hoyt and Schatten in Solar Phys. 179, 189, 1998a; Solar Phys. 181, 491, 1998b). A new dataset has been derived for the RGO daily number of sunspot groups in the interval 1874 -1885. This new dataset attempts to achieve complete consistency between the sunspot data presented in the three main sections of the RGO publications and also incorporates all known errata and additions. It is argued that days for which no RGO solar photograph was acquired originally should be regarded, without exception, as being days without meaningful sunspot data. The daily number of sunspot groups that Hoyt and Schatten assign to days without RGO photographs is frequently just a lower limit. Moreover, in the absence of a solar photograph, the daily number of sunspot groups is inevitably uncertain because of the known frequent occurrence of sunspot groups that exist for just a single day. The elimination of days without photographs changes the list of inter-comparison days on which both the primary RGO observer and a specified secondary comparison observer saw at least one sunspot group. The resulting changes in the personal correction factors of secondary observers then change the personal correction factors of overlapping tertiary observers, etc. In this way, numerical changes in the personal correction factors of secondary observers propagate away from Sunspot Number Recalibration
Grimes' Graves and the peculiar type of implements associated with them being very much discussed at the present time, our Hon. Sec. has invited me, as the finder of a good many of these implements, to give a short paper describing them and some details of the localities.My first two visits to the “Graves” were practically fruitless as far as implements were concerned. However, I stumbled across the pit excavated by Canon Greenwell and brought back a large bone from the debris surrounding it. Subsequent visits showed the best place to search was on the arable land. Every year since then, by the kindness of the agent for the Weeting Estate, I have been enabled to spend several days searching, and have brought away some heavy loads of spoil.
In October last, I was visiting the gravel pits in this neighbourhood, and on reaching one in the parish of Wretton, about half a mile west of Stoke Ferry, one of the men mentioned some bones and an iron spearhead they had found some time previously. I asked to see them, and was taken to another part of the workings, where on a ledge near the surface of the ground was a small hole dug into the face of the pit. Projecting from the hole was a large bone, and stuck into the earth at the side, the spearhead. As they seemed to value their find very lightly, I gave the men a trifle and brought away the articles, asking them to keep any further finds for me.Some six weeks after, I paid them another visit. Nothing further had been done at this particular spot; two of the men, however, volunteered to dig into the side and see if there was anything else. At the first blow of the pick another large bone was unearthed, a practically complete femur. Soon after this an iron knife blade came to light, then on the right side of the body an iron shield boss, and near the head a small iron knife. No other relics were found beyond a few pieces of bone, all with the exception of the two femurs in a very friable state. Three small pieces of the cranium were all that remained of that part. One arm appeared to have been extended above the head, as part of a humerus was lying upright on the remains of the skull. The spearhead must have been near the feet, as it was found first.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
