These anomalies of position are very rare under 

 the torrid zone, and depend probably less on the 

 temperature than on the soil. In the system of the 

 migration of plants, we should suppose that the 

 pinus occidentalis of Cuba had come from Yucatan, 

 before the opening of the channel between Cape 

 Catoche and Cape San Antonio, and not, by any 

 means, from the United States, although the conifer- 

 ous plants abound there, for the species of whose 

 geography we are treating has not yet been found in 

 Florida. 



The following table exhibits the results of observa- 

 tions of temperature, made at Ubajay, in Cuba.
