TTiellae rising above the sides. Fig. 1 1 is a Coalbrooke-dale production, and is a 

 cluster of fungitae, though only 2 appear in the figure. This varies from some 

 of the foregoing in the shape of its head, in the middle of which is a shallow 

 circular cavity, its sides rising a little prominent, and the striae, which commence 

 the inside, pass over the ridge, and are continued to the edges. Fig. 12 is from 

 the same place. The cup-like cavity in this is pretty deep, and radiated with 

 deep strigse : and the sides are marked with very distinct ridges running length- 

 ways, though sometimes interrupted by circular furrows. 



LXXl. An Account of Inoculation, by Sir Hans Sloane, Bart, given to Mr. 

 Ranhy to be published. Anno 1736. p. 31 6. 



Sir H. S. had heard by several reports from China and Guinea, but especially 

 from Turkey, of the inoculation of the small-pox ; and took an opportunity, 

 when Dr. Wm. Sherrard was English consul at Smyrna, to desire the favour of 

 him to inform him of the truth and success of it. In answer to which he told him, 

 that the consul from Venice residing there, a physician. Dr. Pylarini, had taken 

 particular notice of that practice, and had promised to satisfy him about it ; 

 which he did by a letter, which was printed in the Phil. Trans, in 17^6, and he 

 believed at Venice. 



This notice lay dormant till Mr. Wortely Montague, (then ambassador from 

 England at the Porte) and the Lady Mary had inoculated their son at Constanti- 

 nople, and wrote about this practice, and the advantages of it, to the court and 

 their acquaintance here, and afterwards brought into England their inoculated 

 son, in perfect health. 



The princess Anne, then princess royal of Orange, falling ill of the small-pox in 

 such a dangerous way that her life was doubtful, the late Queen Caroline, when 

 princess of Wales, begged the lives of (3 condemned criminals, who had not had 

 the small-pox, in order to try the experiment of inoculation upon them. But 

 Mr. Maitland, who had inoculated at Constantinople, declining for some reasons 

 to perform the operation, lest it should be lost. Sir H. wrote to Dr. Terry at 

 Enfield, who had practised physic in Turkey, to know his opinion and observa- 

 tions about it ; who returned him this answer, that he had seen the practice 

 there by the Greeks encouraged by their patriarchs ; and th^t not 1 in 800 had 

 died of the operation. On his speaking to Mr. Maitland, he undertook the 

 operation, which succeeded in all but one, who had the matter of the small-pox 

 put up her nose, which produced no distemper, but gave great uneasiness to the 

 poor woman. After their recovery, in order to obviate the objection made by 

 the enemies of this practice, that the distemper produced by it was only the 

 chicken-pox, swine-pox, or petite verole volagere, which did not secure persons 

 against having the true small-pox, Dr. Steagertahl, phvsician to the late king,
