ACADEMY OP SCIENCES. 217 



the region of Kadiak Island. Dr. Petermann, in a recent review of the subject, 

 called attention to the need of other observations, and hopes that Prof. David- 

 son will publish all his authorities. But the latter lias not had time to make 

 out an abstract of his authorities and observations. On the recent trip of the 

 U. S. Coast Survey schooner HumhohU, from San PVancisco to Unalaska 

 Island, he advised Mr. Dall, who had charge of the party, to make as many 

 observations on the currents and temperature of the water as his opportunities 

 would permit. This he has done, and in the report he writes to Mr. Davidson 

 as follows : " I made careful observations for currents all the way, and the 

 results are very interesting and appear to confirm, as far as they go, your 

 theory of the currents of this region. That there is a broad (200 or 300 miles) 

 warm current setting to the westward, south-east from the Uiiimak pass, south 

 of the [Aleutian] Islands, there can be no doubt." Short as this announcement 

 is, it has a very important bearing upon the course of the great ocean current 

 of the North Pacific ; and, practically, it bears upon the great circle route 

 between our northern coast ports and Japan. 



Dr. Stout read a copy of a memorial which had been presented 

 to the State and National Legislatures in reference to the cultiva- 

 tion of the Cinchona tree, asking for a suitable selection for and the 

 dedication of a portion of the public domain for the purposes of 

 botanical gardens and sanitariums, to be located on the public lands 

 "which were about to be donated by the National Government to 

 this State. 



On motion of Dr. Stout, it was voted that the Academy, through 

 its officers, should recommend and urge the passage of the bill now 

 before the State Legislature, in such a manner as should best pro- 

 mote the objects thereof, and aid in its final adoption.
