mon with all English men of science, for the 

 brilliant discovery of radium, and its unique 

 properties — the crowning point of the long and 

 painstaking series of researches on radio- 

 active bodies undertaken by Professor Curie 

 and his talented coadjutor, Mme. Curie. 



THE MARINE BIOLOGICAL LABORATORY OF 

 TEE V. 8. FISH COMMISSION. 



The Marine Biological Laboratory of the 

 U. S. Fish Commission at Beaufort, North 

 Carolina, will be opened to investigators on 

 June 1, 1903, for a period of four months. 



The laboratory is well equipped with glass- 

 ware, reagents and running water, both salt 

 and fresh, and is lighted with electricity. The 

 apparatus needed for the collection of ma- 

 terials for investigation is furnished, and an 

 experienced collector will assist in this work. 

 A sailboat and steam launch are available for 

 dredging, trawling and other collecting in the 

 harbor and there is a prospect that facilities 

 will be provided for deep-sea dredging and 

 collecting in the Gulf Stream for a consider- 

 able time during this season. 



Rooms and board for a limited number of 

 men are furnished at about the cost of supply- 

 ing the table and caring for the rooms. A 

 well-trained and experienced cook will be in 

 charge of the ' mess.' All water used on the 

 table and for cooking comes from an artesian 

 well driven on the island to a depth of 236 

 feet. Last season all expenses of living at 

 {he laboratory were covered by $5.25 per week 

 and it is probable that this season they will 

 be a little less. 



It is well knovTn that the marine fauna of 

 Beaufort is very rich and that pelagic organ- 

 isms are especially abundant. The climate is 

 neither unpleasant nor unhealthful. The tem- 

 perature rarely rises above 85° F., and there 

 are few days when a sea breeze does not pre- 

 vail. The atmosphere is humid, but fogs are 

 almost unlvnown. With the water and diet 

 provided at the laboratory mess there is no 

 danger to health. 



Beaufort is connected with Morehead City, 

 the nearest railroad station, situated across 

 the harbor, by a line of launches which stop 

 at the laboratory wharf. The Atlantic and 



North Carolina Railroad connects at Golds- 

 boro with the Southern and Atlantic Coast 

 Line railroads. The laboratory may also be 

 reached by an almost all water route via Nor- 

 folk, Elizabeth City and New Bern. 



Those desiring to occupy tables in the labo- 

 ratory should write for application blanks to 

 Caswell Grave, Johns Hopkins University, 

 Baltimore, until May 28. After that date to 

 Beaufort, North Carolina. 



MONOGRAPH OF NORTH AMERICAN 

 MOSQUITOES. 



Dr. L. O. Howard, of the U. S. Department 

 of Agriculture, is engaged in arranging plans 

 for an elaborate monograph of the mosquitoes 

 of North and Central America and the West 

 Indies under a grant from the Carnegie Insti- 

 tution. It is proposed to devote at least three 

 years to the work, and to make the monograph 

 as perfect as possible, both on the systematic 

 and biological sides. The large collections of 

 the U. S. National Museum and the Depart- 

 ment of Agriculture will be used as a basis. 

 Trained observers will be stationed at differ- 

 ent points, the faunal regions being taken 

 into consideration in choosing localities. Up 

 to the present time the following localities and 

 observers have been selected: Chicopee, Mass., 

 Mr. Frederick Knab; Ithaca, N. T., Mr. 0. 

 A. Johannsen; Minneapolis, Minn., Professor 

 F. L. Washburn; Kaslo, B. C, Dr. H. G. Dyar; 

 Stanford University, Cal., Professor V. L. 

 Kellogg, or an assistant; Salt Lake City, Utah, 

 Mr. R. V. Chamberlin; Victoria, Texas, Dr. 

 W. E. Hinds; Baton Rouge, La., Professor H. 

 A. Morgan; Clemson College, S. C, Professor 

 0. E. Chambliss; Havana, Cuba, Mr. J. R. 

 Taylor; Guanajuato, Mexico, Dr. Alfredo 

 Duges. Additional localities and observers 

 will be selected later. Dr. Howard will be 

 assisted in the systematic work on the adults 

 by Mr. D. W. Coquillett, of the National 

 Museum, and on the larvae, by Dr. H. G. 

 Dyar, also of the National Museum, since both 

 of these observers are skilled in these subjects. 



Volunteer observers are greatly needed, and 

 it is Dr. Howard's hope that persons interested 

 in this subject, and especially those resident
