objects, and the individual number is prefixed to the regular num- 
bers, instead of added, and the day of the month comes first. Thus, 
the example quoted, a specimen collected on August 12, 1899, would 
be 1-12-8-99, 2-12-8-99, and so on. 
Mr. Ball replied that the system referred to by Mr. Caudell related 
to keeping slides of embryological and histological material, and 
while the date system part of it was the same, the application was 
quite different. He had been using the system five years before that 
one was published. He also said that every collector ought to be able 
to give the genus of the specimens taken, but that if he could not, a 
few descriptive words would serve to identify the species when the 
material was worked over. [Ile suggested that it be borne in mind 
in the discussion that the present system was not offered as an 
improvement upon the systems of Messrs. Felt, Hopkins, and Forbes, 
nor for any laboratory where they had help enough to carry out one 
of these systems, but that he thought that it was an improvement 
upon the system in use in the majority of economic laboratories and 
that the date system feature might be incorporated into any system 
to advantage. 
Mr. Ashmead indorsed Mr. Hopkins’s system and said that he 
always put the name of the collector on the specimens received at the 
museum. He ordinarily used two labels, but three were used when 
the original label of the collector was retained. He thought it of pri- 
mary importance to accompany the specimen with the name of the 
collector. 
Mr. Bruner agreed that the name of the collector should always 
appear and said that he used printed labels. 
The session then adjourned to meet at the capitol at 9 o’clock the 
next morning for the purpose of looking over the State museum, 
returning to the high-school building at 10 a. m. for the morning 
session.

Mr. Howard read a paper entitled: 
A PRELIMINARY REPORT ON THE SAN JOSE SCALE IN JAPAN. 
By C. L. Maruatt, Washington, IDOE 
/ 
\ 
The investigation of the San Jose scale in Japan by the writer has 
reached the stage when it is possible to give a definite conclusion on 
the question of original home so far as Japan is concerned. The 
report is provisional only in the sense that some work remains to be 
done in the northern provinces, which can hardly alter the conclu- 
sions, and that time and facilities are lacking to make it full and 
complete. 
In the three months already spent in Japan the writer has explored 
the main islands pretty thoroughly from Tokio southward to the
