Climate and Acclimatization. — In 

 view of the rapid growth of West Indian 

 and South American commerce and the 

 considerable emigration to Cuba and 

 neighboring islands, which our present 

 relations with tlierawill probably bring 

 about, the following extracts from an 

 editorial in the London Lancet are of 

 interest: "The American nation has en- 

 tered upon a new and, in a sense, im- 

 perial policy, which may be regarded 

 as forming an epoch in its history. 

 This brings it face to face with the 

 problem of colonization and acclimati- 

 zation — a problem which we have had 

 to confront long ago and toward the so- 

 lution of which we have ever since been 

 slowly fighting our way by following on 

 the lines of the best practical measures 

 of hygiene known to us. ' The white 

 man's burden ' has proved a tragical one 

 in its drain on the life of the young man- 



hood of this country, notwithstanding 

 the very large measure of success which 

 has attended our sanitary efforts in this 

 direction. The Americans, having taken 

 up their burden, will, no doubt, like the 

 practical people they are, set about their 

 task in a practical way. The four prin- 

 cipal factors in the production of cli- 

 mate, according to Buchan, are distance 

 from the equator, height above the sea, 

 distance from the sea, and prevailing 

 winds. The equatorial region has the 

 most equable climate; tropical regions 

 have much greater variations of tempera- 

 ture than those near the equator, and 

 have a hot and cold or dry and rainy 

 season. The isothermal lines of mean 

 temperature do not supply a graduated 

 measure of the effects of temperature on 

 animal life. So far as climate is con- 

 cerned, no single meteorological infltience 

 appears, however, to equal the effect of
