PERNAMBUCO. 351 



It is easy to understand that, as a general rule, 

 seamen are less exposed than other classes to any of 

 the injurious effects of heat, but it is remarkable that 

 they should enjoy complete exemption. Cases are

 broken water ; but before they drew near, heavy 

 clouds had gathered in the course of a few minutes,
