The yearly rent for the farm of Lyncollysyn is the same, therefore, as was paid for the ruinous "Hospicium Armigeri"; and in the fourteenth century, as Foss has pointed out, the term "esquire" was often used as a synonym for "serjeant." The _Black Books_ also show that in 1457 a payment was made by the society to the gardener of Staple Inn, from which Inn access could be easily obtained to the "great garden" in which the "Hospicium Armigeri" was situated. It would seem not improbable, therefore, that the second and third Lincoln's Inns may, in the year 1438, have been coexistent and under the same rule. But there is at present no evidence that this same society was connected with the Inn in Shoe Lane, which 130 years earlier had belonged to Henry de Lacy. John Fortescue, who received the 40s. for payment to Halssewyll, became serjeant in 1441 and Chief Justice of the King's Bench in 1442. In 1465 he wrote his famous work, _De Laudibus Legum Angliae_, in which he says: "The laws are taught in a certain place of public study nigh to the King's Courts.... There are ten lesser houses or Inns (and sometimes more) which are called houses of Chancery, and to every one of them belongeth 100 students at least, who, as they grow to ripeness, are admitted into the greater Inns, called Inns of Court, of which there are four in number, and to the least of which belongeth 200 students or more." It is clear, then, that the difference between the Inns of Court and Inns of Chancery was recognised in 1465, and it is also certain that one of those four Inns of Court was that to which he himself had belonged, namely, Lincoln's Inn. The others were undoubtedly Gray's Inn and the Inner and Middle Temples. We have seen that in 1387 Lincoln's Inn in Holborn was held directly of the King; we shall find that the other Inns of Court came to be similarly held. In the year 1294, Reginald de Grey, a member of one of the leading administrative and legal families, was Justiciar of Chester. He received in that year from the Dean and Chapter of St. Paul's a feoffment of the manor of Portpool, which they had received in mortmain from Richard de Chyggewell, alderman and mercer of London. It is doubtful whether Reginald de Grey lived here; it is more likely that he acquired the property for the training of his clerks, having found himself under much the same necessity as his contemporaries, Sir John de Metyngham and the Earl of Lincoln. In 1296 he was in association with Prince Edward, as one of the Regency, during the expedition of Edward I. to Flanders. In 1307 he died, when an inquisition was taken, at which the jurors reported that Reginald le Grey was seized at Purtepol of a certain messuage with gardens and one dove house worth 10s. a year, 30 acres of arable land worth 20s. a year, price 8d. the acre, and a certain windmill worth 20s. all held of the Dean and Chapter of St. Paul's.[109]
