ENUMERATION OF FUNGI. 143 
_ plete, which it can scarcely be presumed to be, when Mr. 
_ Cuming's various occupations are considered, would form a 
- the Northern Hemisphere, exactly corresponding with that of 
- Java in the Southern. There is a slight difference in longi- 
_ tude, but not so great as materially to affect the comparison. 
_ The former lie between 5° and 20° N. lat., the latter between 
| 5°.52' and 89.4’ S.L. The climate appears to be nearly the 
. same, the year being divided into nearly equal portions of 
- wet and dry weather; yet not so constant as to be unvaried 
- by occasional days of fine weather in the rising season, or by 
- Showers in the time of drought. The temperature, indeed, 
appears to be more equable in the Philippines. Meyer fixes 
- the mean temperature of the summer between 80° and 82°, 
and that of winter between 70° and 72°, and the mean tem- 
perature of the whole year would be probably somewhat 
short of 77°. Neither does the temperature seem to be 
ever very high; nor does it vary much in the course of the 
day. In Java, the rauge of the thermometer appears to be 
- higher, and the daily variation greater; and there is a regu- 
d lar diminution of temperature from the coast to the interior, 
1 at the rate of two or three degrees of Fahrenheit for every 
. ten miles. Supposing, then, the present collection to be any 
_ thing like an approximation to the Mycology of these exten- 
- sive islands, we shall not be surprised to find the number 
Much larger in Java, and we may expect to find many of the 
. Species different. The number of species described by Jung- 
- huhn, is one hundred and thirteen, but some addition ought 
probably to be made to this. The number in Mr. Cuming's 
collection is about- thirty-five, exclusive of two or three of 
the larger P olypori, which I have not had an opportunity of 
examining. Amongst these, 4th only of the species are com- 
` mon to Java and the Philippines, and out of these four are 
Species of Polyporus, common to all tropical countries. It 
may, however, be interesting to see to what families these are 
referrible, and what are the predominant forms. Of Mr.
