SOCIETIES AND ACADEMIES. 

 BIOLOGICAL SOCIETY OF ST. LOUIS. 



The Biological Society of St. Louis was 

 organized March 3, 1903. Dr. A. W. Greeley 

 was elected president. The membership num- 

 bers about fifteen at present and increases 

 at each meeting. It speaks well for the fu- 

 ture of the society that the present member- 

 ship is exceptionally homogeneous and har- 

 monious, and that a place is rarely vacant at 

 the meetings. 



Although but four meetings have been held, 

 and the society is yet in the formative stage, 

 gratifying progress has been made. Current 

 literature in botany, zoology and physiology 

 has been reviewed. Several of the reviews 

 have been given by members whose personal 

 and professional relations with the authors 

 gave to the reviews an unusual interest. Con- 

 siderable original work will doubtless be pre- 

 sented during the next year. 



At present steps are being taken looking 

 toward closer relations with the Academy of 

 Science of St. Louis. The meetings of the 

 society are held on the last Tuesday evening 

 of the year excepting in the months of June, 

 July and August. Visiting biologists are cor- 

 dially invited to attend.

DISCUSSION AND CORRESPONDENCE. 



THE advantages OF THE GOVERNMENT CINCHONA 



PLANTATION IN JAMAICA AS A TROPICAL 



BOTANICAL STATION. 



In a month's residence this spring, .at 

 Cinchona, during which time I was daily oc- 

 cupied in field work within a radius not 

 greater than ten miles from the Cinchona 

 garden, I was much impressed with the advan- 

 tages of this location for a permanent tropical 

 botanical station in America. After conver- 

 sation and correspondence with botanists who 

 have worked in this and various other tropical 

 regions, I have become thoroughly convinced 

 that, for such a station, no other location 

 combines the many superior advantages of 

 Cinchona. 



A luxuriant and varied flora to meet the 

 diverse demands of American botanists wish- 

 ing to work on problems of distribution, de- 

 velopment or physiology of tropical plants is, 

 of course, the first requisite of a locality pro- 

 posed for such a station. Associated with the 

 extremely varied physiographic and climatic 

 characters of the region accessible from Cin- 

 chona is a flora which makes this location pre- 

 eminently advantageous for botanical work. 



Cinchona is on a hill which forms a spur 

 projecting southward from the Blue Moun- 

 tain Range. Within three miles of Cinchona, 

 in the Blue Mountains, is the well-known 

 Morce's Gap, through which moisture-bring- 

 ing clouds drift almost continuously, thus 

 giving rise, near the Gap, to a dense and 

 greatly varied vegetation especially rich in 

 lichens, bryophytes and pteridophytes. In 

 the deep valley of the Mabess River, just north 

 of this, the vegetation is even more luxuriant 

 than about the gap itself. Other moist gaps, 

 many high mountain peaks and several deep 

 river valleys directly below Cinchona Hill have 

 a luxuriant plant covering of mesophytic type. 

 Nearer Cinchona are the more xerophytic 

 foothills of the Blue Mountains, and below 

 these are the still drier plains about Kingston. 

 These different regions, to reach the most 

 distant of which requires not more than a 

 two-day trip from Cinchona, afford a com- 

 plete series of moisture conditions and plant
