" Juice from 10 average oranges. This juice was filtered through Berkefeld filters and 
bottled in sterile bottles. 
b Juice from 12 average oranges. 
¢ Analysis of the juice bottled as described under a, after a storage period of about one 
year and eight months. The state of preservation was perfect. 
This variety of orange is so inferior to the naranjita in every 
respect that we see no future for it unless it is improved. 
THE LIME. 
Dayap, the common Tagalog name for the lime, Citrus lima 
Lunan, is a true lime which is grown only in small quantities 
in the Philippines. It is a fruit of good quality, and, when 
available in quantities, will be comercially valuable. (Plate IV, 
fig. 2.) 
The cost of the limes in the Manila market is about 1 cen- 
tavo each. When pressed by hand each one yields about 7 
cubic centimeters of juice. A number of bottles of this juice 
were preserved by heating between 60° and 70° in the manner 
described under the naranjita orange and it was found to keep 
perfectly and retain its flavor. All persons who have tasted this 
bottled juice pronounce it excellent and superior to imported 
bottled lime juice.® 
* Almost all of the lime juice heretofore offered for entry in the 
Philippine Islands has been found to contain excessive quantities of sul- 
phurous acid.
