nave been continued. The receiver of the rain-gauge has 
been removed to the roof of the museum and is connected by 
a leading pipe of small caliber with the measuring cylinder 
in the physiological laboratory. In a comparison of records 
made in this manner with a gauge on the ground in the nur- 
sery, no material differences were found, and it has been 
decided to take the records only from the newly installed 
instrument. 
Early in the year I was called upon to spend several days 
in attendance at the County Supreme Court in order to give 
testimony as to the conditions of rainfall during 1902, in a 
suit brought by a contractor to recover additional cost of con- 
struction from the city. 
Laboratories 
The appropriation for the laboratories has been expended 
in the increase of the equipment at all points, an extension 
made necessary by the constantly widening scope and im- 
portance of the investigations pursued in the Garden. Pro- 
fessor W. J. Gies has continued to act as consulting chemist, 
visiting the laboratories for the purpose of conference with 
persons engaged in chemical researches, once and some- 
times twice weekly during the collegiate year. Mr. 
Gruenberg, in coéperation with Dr. Gies, completed an in- 
vestigation of the chemical properties of the so-called ‘ bas- 
tard logwood,” which is a disturbing factor in the dyewood 
markets of the West Indies, and the results were described in 
the Bulletin Torrey Club, being reprinted as Contribution 
No. 54 under the title ‘‘ Chemical Notes on Bastard Log- 
wood.” Other results are in course of preparation for the 
printer. 
Dr. C. S. Gager, professor of biology in the State Normal 
College of New York, at Albany, has secured leave of ab- 
sence from his chair for a year, and acts as assistant in the 
laboratories. Dr. Gager devoted the greater part of his at- 
tention to an investigation of the anatomical expression of 
the qualities of hybrids of the evening-primroses, making
