This plant is rare in 'Jamaica. I have not obferved it above once in that ifland; 

 it was in a pond between Mr. James's, and Doctor Skene's, in St. James's : but 

 it is very common in A?itigua y where the greater! part of their waters is collected 



and prefcrved in pond 



» the waters always frem and cool ; which would 



s, 



for the public ufe. It grows and thrives very luxuriantly 



in thefe refervoiis, and keeps 

 be greatly fubject. to putrefaction, and charged with a multitude of infects, had they 

 continued expofed to the heat of the fun. It has its inconveniences, however, and 

 thofe not very trifling; for the plant is, of its own nature, acrid; and when the 



droughts fet in, and the waters are reduced very low, (which frequently happens in 

 that ifland) they are over-heated, and fo impregnated with the particles of this ve- 

 getable, that they frequently give bloody-fluxes to fuch as are obliged to ufe 

 them at thofe feafons: but this inconvenience may be, in fome meafure, remedied, 

 by mixing flower, or fome other fheathing fubftance with it, if neceflity obliges the 

 ufe of it in fuch a ftate. Its acrimony gives me room to think that it is not the Stra- 

 iioles of Prof p. Alpinus y or Bauhin.
