[N. S. Vol. VIII. No. 202. 



have been safely sent from this country to 

 Europe, Asia and Australia. Eggs of marine 

 species are shipped in tightly-closed jars con- 

 taining water, and may be expected to arrive 

 with not more than 50 per cent, loss at points 

 that may be reached in twenty-four to thirty 

 hours. Shad and pike-perch eggs do not stand 

 distant shipment well unless accompanied by 

 an attendant, but may be sent unattended short 

 distances (covered in ten hours or less) either 

 on trays or in cans containing water. Trout 

 and salmon eggs are not likely to survive long 

 shipments except immediately after fertilization 

 and after becoming ' eyed.' 



Some of the places at which hatcheries of the 

 Commission are located, the kind of eggs avail- 

 able at each station, and the approximate period 

 when they can be supplied, are as follows : 



"Woods Hole, Mass. — Cod, Nov. 15 to Jan. 30 ; flat- 

 fisb, Feb. and March ; lobsters, April to June. 



Gloucester, Mass.— Cod, Dec. 1 to Feb. ; pollock, 

 Nov. and Deo. 



East Orland, Me.— Atlantic salmon, Oct. to Feb. 



Green Lake, Me. — Brook trout, Nov. to Feb. ; land- 

 locked salmon, Nov. to Feb. ; golden trout, Nov. 

 and Dec. ; lake trout, Nov. to Feb. 



St. Johnsbury, Vt. — Brook trout, Oct. to Jan. 



Washington, D. C. ; Havre de Grace, Md., and Glou- 

 cester, N. J.— Shad, April 15 to June 1. 



Wytheville, Va. — Rainbow trout, Dec. to Feb. 



Erwin, Tenn. — Brook trout, Nov. and Deo. 



Put-in Bay, Ohio.— Whitefish, Dec. 1 to Feb. 1 ; lake 

 herring, Dec. and Jan. ; pike perch, April. 



Northville, Mich.— Lake trout, Oct. to Jan. ; brook 

 trout, Nov. to Jan. ; Scotch lake trout, Nov. to 

 Jan. 



Duluth, Minn.— Lake trout, Oct. to Feb. 



Manchester, Iowa. — Brook trout, Nov. to Jan. ; lake 

 trout, Nov. to Jan. 



Neosho, Mo. — Rainbow trout, Dec. and Jan. 



Bozeman, Mont. — Grayling, June ; black-spotted 

 trout, June. 



Leadville, Colo. — Brook trout, Oct. to Jan. 30 ; 

 black-spotted trout, June ; rainbow trout, June ; 

 Scotch lake trout, Oct. and Nov. 



Baird, Cal. — Quinnat salmon, Aug., Sept., Dec. and 

 Jan. 



Clackamas, Oregon. — Quinnat salmon, Nov. 1 to 

 Feb. 1. 



When eggs other than those regularly handled 

 by the Commission are desired, an attempt will 

 be made to obtain them. 



Persons intending to take advantage of this 

 opportunity should, in order to save time, com- 

 municate directly with the superintendent of 

 the nearest station at which the desired eggs 

 are being developed, informing him definitely 

 regarding the number and kind of eggs wanted, 

 the time when they are to be sent, the addresses 

 to which they are to go, and the dates, if any, 

 on which subsequent lots are to be shipped. 

 The transportation companies will receive full 

 instructions from the Commission as to the care 

 of the eggs during shipment, and should also be 

 asked by the consignees to make special efforts 

 for prompt delivery. 



The Commission has from time to time fur- 

 nished fish eggs in response to special requests. 

 The fact that a few universities and colleges have 

 asked for eggs suggests that other institutions 

 may desire such material. The only expenses 

 to be incurred are the charges for transportation 

 and the cost of special packing boxes ; the latter 

 item is small and may be rendered compara- 

 tively insignificant by the return of the empty 

 boxes to the various stations in case additional 

 consignments of eggs are requested.

ON A SUITABLE NAME FOE THE NEW PLANET. 



To THE Editor of Science : The unique 

 character and singular orbital position of the 

 little planet DQ, recently discovered by Mr. G. 

 Witt, give the question of its nomenclature 

 more interest than usually attaches to such 

 matters. Of course, the selection of a name, by 

 courtesy and the precedent of custom, must be 

 left to the taste and discretion of the discoverer. 

 But it is trusted that he will pardon suggestion 

 with regard to it, since it is a matter that other 

 astronomers may take a legitimate interest in. 



It is manifest that this little object is destined 

 to play a r61e in our astronomy of very great 

 importance. It opens up, at a stroke, an un- 

 expected and royal road to the problem of the 

 solar parallax, as well as to the nutation, the 

 moon's mass and the aberration. Melancholy 

 as the statement may be, it will reduce many of 

 the existing discussions of these elements to the 

 value of waste paper, records of futile effort.
