V. 
REGULATIONS REGARDING THE BORROWING 
OF SPECIMENS FROM THE HERBARIUM OF 
THE BUREAU OF SCIENCE, MANILA, P. I. 
Experience in lending and borrowing herbarium 
specimens has shown it not only desirable but neces¬ 
sary that both the borrower and the lender should 
keep exact duplicating records of such loans. For 
this purpose, we have used the experience of the 
Gray Herbarium in adopting the following rules: 
Specimens may not be retained longer than needed 
for study. 
All specimens borrowed at one time must be returned 
at one time. 
Specimens may be returned only by registered mail 
or by prepaid express. 
On receipt of specimens, the attached Coupon No. 1 
must be carefully verified, signed, and returned by 
the borrower. 
Coupon No. 2 should be retained by the borrower 
until the return of the specimens and then mailed* 
under separate cover to the Herbarium, Bureau of 
Science, Manila, Philippine Islands. 
When borrowed specimens are returned to the 
Herbarium, Bureau of Science, the borrower will be 
at once informed of their arrival, and then, but not 
until then, may feel free from further responsibility 
regarding them.
