TuHeE death has occurred of Mrs. Margaret

THE nineteenth summer meeting of the 
American Mathematical Society will be held 
at the University of Pennsylvania on Tuesday 
and Wednesday, September 10-11, 1912. 
Tue Society of American Bacteriologists 
will hold its annual meeting in New York 
City at the close of this year. 
THE next annual meeting of the Biochem- 
ical Association will be held at the College of 
Physicians and Surgeons, Columbia Univer- 
sity, on Monday evening, June 3. Besides the 
usual business meeting there will be a scien- 
tific program consisting of the presentation 
of reports of recent researches by members of 
the association. This scientific session will 
be the first of an annual series of similar 
meetings. Abstracts of the reports will be 
published collectively in the June issue of the 
Biochemical Bulletin. 
Me. J. B. Tyrrewt, the geologist and min- 
ing engineer, is to lead the Ontario govern- 
ment expedition into the north to locate the 
five-mile strip which the province is to receive 
SCIENCE 
689 
from the Dominion. Although the route has 
not been settled, the party will probably pro- 
ceed first to Winnipeg about the end of May, 
and thence to Lake Winnipeg to Port Nelson, 
much of the journey by canoe. At the mouth 
of the Nelson River, some time will be spent 
in locating the ten-mile strip which Ontario 
will have as a terminus for the Temiskaming 
and Northern Ontario Railway, should it be 
decided to extend the line there. The party 
will then head for the south, and a larger part 
of the five months will be taken up in explor- 
ing the 50-mile stretch along Hudson Bay, 
anywhere in which the government has a 
right to choose its five-mile strip. 
Prorressor C. H. Eicznmann, of the Indi- 
ana University and the Carnegie Museum, 
after a successful exploring trip on the rivers 
of Colombia, returned by the Alemania on 
April 15. The main object of this expedition 
was to secure a series of the fishes of Co- 
lombia. After collecting in the lower courses 
of the Magdalena River, he ascended that 
river to an elevation of one thousand feet at 
Girardot. From here a side trip was made 
to Bogota. After returning to Girardot, he 
went by pack-train, via Ibagué, Cartago, Cali 
to Caldas on the Pacific slope. From Caldas 
he went by train to Buenaventura on the Pa- 
cific Coast. In this trip collections were made 
in all the streams crossed and especially in 
the Rio Dagua, flowing into the Pacific from 
an elevation of 5,000 feet to tide water. From 
Buenaventura he went up the San Juan, first 
by steamer and later by dug-out canoe with 
Indians to Istmina. From Istmina the divide 
between the Pacific and Atlantic slopes was 
again crossed by horse to Tambo. From 
Tambo, at first small canoes and later one 
larger canoe took him and his effects on the 
San Pablo and Rio Quibdo to Quibdo. As 
the navigation of all of these streams was 
very irregular on account of the unusually dry 
season, special arrangements were made to 
take him from Quibdo to Rio Sucio where, 
on account of a scare of pirates, the regular 
steamer from Cartagena was delayed await- 
ing the arrival of a company of soldiers from
