BOTANICAL INVESTIGATION IN MIDDLESEX. 381 



Mr. S. D.' * Vol. iii. (commencing January, 1709) is imperfect, and perhaps 

 the publication was discontinued before its end. The number for August 

 1709 was not printed till 1710, with a new publisher. 



In the September number Petiver commenced a catalogue, which, if ever 

 completed, has eluded our search. It is called ' Botanicum Londinense ; or, 

 the London Herbal. Giving the names, descriptions, and virtues, &c. of such 

 Plants about London, as have been observed in the several monthly herbor- 

 izings made for the use of the young apothecaries, and others, students in 

 the science of Botany, or knowledge of plants,' ' The first division or walk,' 

 containing ' such plants as grow plentifully nearest the city, viz. : within 

 a mile, as bet. London and Islington, &c. or about that distance ' occupies the 

 whole number, except the first two pages. The plants, eighty-eight in 

 number, are arranged after Pay. 



The number for October f is imperfect. The first two pages are on 

 British Bees, and then the Botanicum Londinense continues thus : ' Having 

 given you in our last an account of such plants as most plentifully grow on 

 the north side of the City . , . . we now proceed to the second walk or 

 division, which contains such plants as are commonly found west of London, 

 viz. between Westminster and Chelsea, &c.' Of this we have seen no 

 complete copy ; many portions cut out from it lie loose in Petiver's her- 

 barium, in which are also a few with the printed date of ' November 1709,' 

 apparently from a subsequent number. 



The Memoirs seem to have died out gradually; yet in 1715 the London 

 Herbal is advertised J as a separate publication, ' price 2s. 6c?.' "Was this a 

 reprint ? We have never seen it alluded to, nor have we met with a copy. 

 If it exists, it must be of value as an account of the botany of the suburbs 

 at the time. 



In the year 1711 Petiver made a journey into Holland, returning in the 

 autumn. At Leyden he had a friend, named Judkin (from whom are 

 letters in Sloane MSS. 4046) with whom he seems to have stayed. A full 

 account of this visit will be found in a letter to Patrick Blair (Sloane 

 MSS. 3338, fol. 28), where he tells us that the chief object of his going over 

 was to purchase for Dr. Sloane the best part of Dr.Herraann's Museum.§ 



In the autumn of 1712 he made a ' trip to the Bath and Bristow,' and in 

 1715 he went with James Sherard to Cambridge, Newmarket, &e., of which 

 latter tour there is a description in Sloane MSS. 2330, fol. 914. 



A set of figures of British plants was taken in hand by Petiver in 1713. 

 The first volume contains 50 plates on copper, containing more than 600 

 figures, and in 1715 this was supptemented by 22 more, increasing the 



* Samuel Daniell, ' the person who composed a voyage to the Levant,' and collected for 

 Petiver there. 



t Alluded to by Petiver in 1712, in a letter to Blair, as ' now very scarce to be had.' 

 {Sloane MSS. 3338, fol. 86.) 



X At end of the Hortus Medicinalis Peruvianus. 



§ 109 lots were purchased for apparently little more than 14?. See a letter from Petiver 

 to Sloane in MSS. 3337, fol. 160, dated 'June 29, 1711 ;' and Sloane MSS. 4055, 155, dated 

 ' June 18, Leydeu.'
