One remark it would appear arises out of these observations, viz. that the laws of attraction and gravitation seem to require, for the proper regulation of the whole system, that where a number of bodies of various sizes revolve round one common centre, the larger body should revolve at a certain relative distance from that centre. Thus Titan, like a huge pendulum, seems to sway and maintain the regularity of the minor system, just as Jupiter may be imagined to do in the great one.
I must not intrude too far on your valuable space, but there remain some interesting points for discussion in the Saturnian system.
The extract from an unpublished MS. given by A REGENT M.A. OF CAMBRIDGE refers to the year 1620, as will appear from the following passages in Anthony à Wood's _Hist. and Antiq. of Univ. of Oxford_.
"1614.--In the latter end of the last and beginning of this year, a spirit of sedition (as I may so call it) possessed certain of the Regent Masters against the Vicechanc. and Doctors. The chief and only matter that excited them to it was their sitting like boys, bare-headed, in the Convocation-House, at the usual assemblies there, which was not, as 'twas thought, so fit, that the Professors of the Faculty of Arts (on which the University was founded) should, all things considered, do it. The most forward person among them, named Henry Wightwicke, of Gloucester Hall, having had some intimation of a statute which enabled them to be covered with their caps, and discovering also something in the large west window of St. Mary's Church, where pictures of Regents and non-Regents were sitting covered in assemblies before the Chancellor, clapt { 131} on his cap, and spared not to excite his brethren to vindicate that custom, now in a manner forgotten; and, having got over one of the Regents to be more zealous in the matter than himself, procured the hands of most, if not all, of them to be set to a petition (in order to be sent to the Chancellor of the University), for the effecting and bringing about the matter. But the Vicechancellor, Dr. Singleton, having had timely notice of the design, sends a full relation of the matter to the Chancellor; whereupon answer was returned, that he should deal therein as he should think fit. Wightwicke, therefore, being called into question for endeavouring to subvert the honour and government of the University, whereby he ran himself into perjury (he having before taken an oath to keep and maintain the rites, customs, and privileges of the University), was banished, and his party, who had proved false to him, severely checkt by the Chancellor.
