16 MISSOURI BOTANICAL GARDEN BULLETIN 
At the meeting of the American Association for the Ad- 
vancement of Science, Atlanta, Dec., 1913, the following 
papers were presented by members of the staff, and graduates: 
B. M. Duggar, “The Effect of Temperature Upon Certain 
Tissue or Cell Processes and Some Problems Involved.” 
B. M. Duggar and J. 8. Cooley, “The Effect of Certain 
Surface Films and Powders on the Rate of Transpiration.” 
B. M. Duggar and A. R. Davis, “A Preliminary Report 
on the Isolation and Identification of the Enzymes of Fucus 
vesiculosus.” 
G. L. Foster, “Indications Respecting the Source of Com- 
bined Nitrogen Used by Ulva lactuca.” 
Jacob R. Schramm, “The Relation of Certain Grass-Green 
Algae to Elementary Nitrogen.” 
The papers last noted will appear in the first two numbers 
of the new scientific quarterly journal of the Garden, together 
with others dealing with the following topics: A. G. Nolte, 
Regarding a new method for the bacteriological examina- 
tion of air; L. O. Overholts, Native Polypores of Ohio; 
J. R. arity Koss relation of certain s of 
green _to elementary nitrogen, an ure culture 
methods m the algae; E. A, Burt, A general statement pre- 
liminary to a monograph of the Thelephoraceae; J. M. 
Si Notes preliminary to a monograph of the genus 
necio. 
_ Laboratory Facilities—Marked Na has been made 
in adjusting the arrangements of the iahewatce to the new 
demands, and in strengthening the facilities for research, 
at the same time segregating the different aspects of the work 
with a view to higher efficiency. The first floor of the lab- 
oratory wing of the main building is used, as in previous 
years, for a lecture room and office. The second floor is now 
occupied by (1) a large conference room serving as head- 
quarters for the study and microscopic work of graduate 
students, also as seminar room; (2) a small balance room; 
and (3) a staff research laboratory for physiology and bac- 
teriology. The third floor is given up to one large ri- 
mental laboratory, which is being equipped, as rapidly as 
possible, with all the facilities for the most exacting experi- 
mental studies. During the year there have been added 
chemical tables, lockers, and cases, an additional transfer 
room, a four-compartment incubator, new precision appa- 
ratus, a large water still, and much additio: 2 and 
chemicals, affording excellent opera for research 
work, especially along physiological lines. |
