THE DISEASES OF THE CREW. 325 



drinking some Chilian wine in the country : this 

 soon passed over, but the following day he had 

 severe pains in the head. The wine was probably 

 mixed with some vegetable substance, for instance, 

 LobeliaTupaf L., to make it more intoxicating.

VOYAGE FROM CHILI TO KAMT5CHATKA. 

 NO DISORDERS. 



1 HE voyage from Chili to Kamtschatka, was so 

 fortunate for the health of the crew, that, in a 

 period of three months and a half, none suffered 

 from any internal complaint. 



There was, in fact, no want of weather which 

 might produce diseases ; there were many days 

 on which it rained incessantly, and the transition 

 from a hot to a cold climate was pretty sudden and 

 sensible. 1 ascribe the constant health of the crew 

 to our great distance from high land during almost 

 the whole of this long voyage. The low coral 

 islands, of which we passed so many, and so near 

 at hand, do not produce in this respect any of the 

 effects of land : they cause no difference of tempe- 

 rature, either in the water or the air ; they exhale 

 no moisture, produce neither dews nor tempests, 

 and do not impede the course of the winds.
