ably at the mouth, and his belly swelled greatly. He purged very much soon 

 after he was dead, but not before. 



As this poor man had taken this dose before his family were up, no one could 

 imagine from what his disorder arose ; and consequently the apothecary, who 

 was called to him, was able to form a judgment of his case only from the symp- 

 toms ; as on his coming he found his patient senseless, and who had not, while 

 his mind was undisturbed, told any one the probable cause of his complaints. 

 He took from him however about 10 oz. of blood, and endeavoured to get some 

 vinum ipecacuanhae into his mouth : but his jaws were closed so fast, not above 

 a spoonful passed, and that by the accident of his mouth opening of itself. 



The symptoms, with which the person above-mentioned was attacked, were 

 much the same as those which were observed in the French prisoners, who were 

 poisoned by the same root at Pembroke. In both instances occurred those se- 

 vere muscular spasms, which kept the under jaw so close to the upper, that, 

 while the spasm continued, scarcely any force could separate them. In both 

 instances likewise a considerable time passed before the persons, who had eaten 

 of this root, though they had taken enough of it to destroy them, perceived 

 themselves disordered by it. 



CXV. Extract of a Letter to John Eaton Dodsworth, Esq. from Dr. George 

 Forbes of Bermuda^ relating to the Patella, or Limpet Fish, found there, p. 859. 



As a curiosity for your esteemed friend Mr. Theobald, the captain will deliver 

 you 1 fishes, quite singular here, and never before observed among us. The one 

 is or the shell kind, and changed its figure so often, that it was difficult to make 

 a drawing. However it was at length taken in two different positions, as in fig. 

 21, 22, pi. xi. The small one may be called the sea-batt ; and in some sort re- 

 sembles that species of animals when it is swimming. 



Additional Remarks by Charles Morton, M. D., F. R. S. 



The patella, or limpet-fish, whose generic characters, as enumerated by bishop 

 Wilkins, are, that it is an exanguious testaceous animal, not turbinated ; a uni- 

 valve, or having but one shell ; being unmoved ; sticking fast to rocks or other 

 things; the convexity of the shell somewhat resembles a short obtuse-angled 

 cone, having no hole on the top. - 



CXVL On the Cinnamon, Cassia^ or Canella. By Taylor White, Esq, 



F. R. S. p. 860. 



The cinnamon, cassia, or canella, are shrubs of no great height: they grow 

 in Ceylon, Malabar, Java, Sumatra, and other places in the East Indies ; as in 

 the island of St. Thomas, and on the coast of Coromandel. They are described 

 by Mr. Ray, in his History of Plants, vol. ii. f. 1559, under the title de Arbori-
