1904] COOLEY—BOTANICAL GARDEN AT NAPLES 437 
and growing freely under conditions unnatural to them at home, 
and the marvel is that they find it so easy to do it. 
It is instructive to run over the climatic conditions that exist here 
and contrast them with what can be gathered concerning those of 
other lands which have representatives here. Naples lies in the warm 
temperature region of winter rains. The latitude is 40° 52’, the 
longitude 14° 15’ east. The garden is a short distance from the sea, 
from 31.30 to 44.50™ above it, and lies on a slope that looks southeast 
to Vesuvius. Back of it and protecting it from the north winds, rises 
the hill of Capodimonte, on which is an observatory from which the 
meteorological observations were taken which are given in the table 
low. Since the hill is much higher than the garden and more 
exposed, the conditions are not quite those which hold in the garden 
itself, 103™ below. In an account of the garden published in 1867 
by Pasguate, a former director, some of the climatic conditions are 
discussed. In 1846 there was a summary made of the observations 
of temperature for twenty-four years. The medium temperature for 
these years was 1 5-66° C. The highest temperature recorded was 
for July 17, 1841, 39° C.; the lowest was February 21, 1845, —5.8° C. 
The period of greatest heat succeeds July 25, and that of greatest 
cold January 24. Specially cold nights are recorded, when the 
femperature sank to —7° C. and —8° C. Such periods of extreme 
Cold are rare, occurring perhaps only once in ten years. The ther- 
Mometer seldom sinks to the freezing-point, and hoar frosts are most 
Unusual. The table given below is for the year 1902, and is taken 
from the monthly reports published by the observatory of Capodi- 
Monte, 149™ above sea-level. 
The rain falls for the most part in the winter, but the amount that 
in special months varies from year to year. In general it is 
steatest from October to February, and least in June, July, and 
“gust; in 1902 sinking to zero in July. 
SCHIMPER divides the globe into regions according to the relative 
‘Mounts of rain during the year and the seasons in which it falls. 
If we follow this classification in arranging the plants of the garden, 
Stouping them with the countries where they are native, we shall be 
able to make Some interesting comparisons.
