order to verify Mr. Winkler's assertions. The weather was dry, and very fit 

 for electrical experiments. Not the least alteration had been made in Mr. 

 Winkler's globes. The largest globe, said to contain opobalsamum, was first 

 put to the trial : it was first rubbed a considerable time with a dry hand chalked, 

 and the snaps at the prime conductor were but weak ; but on rubbing the globe, 

 first with the cushion and afterwards with read leather, the snaps were much 

 stronger ; and Mr. Canton, as well as another gentleman present, were electrized 

 by turns with it : but all this while no smell of the balsam could be perceived 

 by any of the company, either on the equator of the globe, or the persons elec- 

 trized, or the prime conductor, or any of the rubbers made use of;, though for 

 this purpose they carefully observed, not only the method suggested by Mr. 

 Winkler, but such others as appeared the most conducive to the present pur- 

 pose. When the globe was heated, indeed, by applying the nose to the mount- 

 ing, a smell of resin in it was perceived ; but this was all. 



They next tried the less globe containing cinnamon, and most punctually ob- 

 served Mr. Winkler's directions : but all endeavours were to no purpose, for 

 they could never, after many trials, either smell the cinnamon, or make the 

 electricity the least perceptible on the prime conductor. 



They then began with the tubes : but not one of the company, after very 

 many trials in different ways, could perceive the least odour of the substances 

 contained, either on the outside of the tubes, or on the substances electrized by 

 them. They thus spent more than 1 hours without success, in endeavours to 

 see the effects proposed by Mr. Winkler ; for they were not able to verify them 

 in one single instance. 



XXXV. On the Bishop of London! s Garden at Fulham. By Mr. fVilliam 



rVatson, F. R.fS., p. 241. 



Mr. W. here gives an account to the k. s. of the remains of that famous botanic 

 garden at Fulham, where Dr. Henry Compton, formerly bishop of London, planted 

 a greater variety of curious exotic plants and trees, than had at that time been 

 collected in any garden in England. This excellent prelate presided over the 

 see of London from the year l675 to 1713 ; during which time, by means of a 

 large correspondence with the principal botanists of Europe and America, he in- 

 troduced into England a great number of plants, but more especially trees, 

 which had never been seen here before, and described by no author : and in the 

 cultivation of these, as we are informed by the late most ingenious Mr. Ray, he 

 agreeably spent such part of his time, as could most conveniently be spared from 

 his other most arduous occupations. 



Mr. Ray, in the 2d volume of his history of plants, which was published in 

 the year l688, gives us a catalogue of the rare and exotic trees and shrubs.
