" Nov. 3. Upou looking at the moon this evening I saw Linne as a well- 

 defined crater, with little of that cloudy haziness which has lately supervened 

 it ; also by glimpses I saw a dark line (as if a shadow) on the side nest the 

 sun, and ■\vithin the crater. Saw also the smaller crater as a black point." 



Mr. Prince adds, " On the following evening the cloudy spot had completely 

 obscured the crater again. I could not detect any crater"*. 



11. 1867, Dec. 3, 5"^ 0™. Messrs. Joynson and Williams, of Livei-pool, 

 saw the shallow crater. The record of the observation is as follows : — " The 

 ' shallow ' oval crater was quite distinct, and south preceding there appeared 

 to be the commencement of another (see ante, p. 7, Aiig. 6, S""). The thin 

 black line of shadow was well defined ; but the impression given was that 

 the hill is either very low and rounded, or, if not low, that the sides are of a 

 very gradual ascent. The ' small ' crater could not be seen." 



The Small Cratee. 



There is no record whatever of this object as a crater until 1867, Feb. 11. 

 As a wliite lull or hJacJc jioint it appears to have been noticed about two months 

 earher, From the time when Herr Schmidt suspected that a change had 

 taken place in Linne until December 13, 1866, nothing was seen but the 

 large white spot. On this day Schmidt discovered a delicate shadow-project- 

 ing hUl. The next evening, December 14, Mr. Buckingham saw a shadow, 

 or very black point. Dec. 26, and 1867, Jan. 2.5, Schmidt again saw these 

 objects ; and on Feb. 11, 1867, Secchi found a small crater. During March, 

 April, May, June, and JiUy, this small crater was seen by several observers, and 

 estimates of its diameter given. On Julj- 9 its diameter was measured by Mr. 

 Huggins. The following are the most important observations of this object :^ 



" 1866, Dec. 13. [Herr Schmidt.] Abends. Lxift mitunter recht gut. 

 Die zunehmeude Phase hatte soeben den Linne iiberschritten. An seiner 

 Stelle war Anfangs nicht der geringste Gegenstaud zu cntdccken, obgleich die 

 dortigen feinen, 10-30 Toisen hohen Adern sich eben so dcutlich darstellten, 

 als die kleuien Crater im Nordwesten. Untcr Anweudung einer 300-maligen 

 Vergrossening bemerkte ieh am Orte des Linne, der sich nicM durch helleres 

 Licht auszeichnetc, eJnen iiusserst feinen schattenwerfenden Hiigel, fiir den 

 eine sorgfaltige Schiitzung 300 Toisen Durchraesscr, imd 5-6 Toisen Hohe 

 ergab. Gegen 6 Uhr betrug die SonnenhiJhe fiir den Horizont des Linne 1| 

 Grad. "\Yeder innerer noch ausserer Schatten war sichtbar ; das ganze Cratcr- 

 gebirge fehlte durchaus, uud ich sah urn- glatte graue Ebene." 



Translation. — Dec. 13, evening. Air at times very good. The morning 

 terminator had just passed over Linne. At first there was not the smallest 

 object to be discovered in its place, although the delicate ridges about, of 

 from 1 0-30 toiscs in height (between 60 and 200 English feet), were clearly 

 visible, as well as the small craters in the N.W. By applying a power of 

 300, 1 remarked in the place of Linne, which did not show itself distinctly 

 through the brighter light, an extremely dehcate shadow-projecting hill, for 

 which a careful estimation gave a diameter of 300 toises (about 1918 English 

 feet), and a height of 5-6 toises (between 30 and 40 English feet). Towards 

 6 o'clock, the sun's altitude for the horizon of Linne amounted to l°-5. 

 Neither interior nor exterior shadow was visible ; the whole crater-mountain 

 was entirely wanting, and I saw only a smooth grey plain. 



1866, Dec. 14. Mr. Bucki:n-giiam. 6'' to 7'', ecjuatoreal 9 inches aperture, 

 power 240 and 361. Mr. MacguU of Glasgow present. " Air unsteady, but 



* 1867, Not. 3, S"* 30'». Mr. Lockyer found Linne Tery difficidt to see. It was only 

 a white patch. — Astronomical Kegister, Ko. CO, Dec. 1867, p. 254.
