Brunswiek coast (Lat. 45° 3' 'N., Long. 66° 28' 

 W.) and -was found on August 8, 1920, on the 

 shore at " Ponta Delgada, Floras, Azores " 

 (apparently Delgada Point of the Hydro- 

 graphic chart, Lat. 39° 31' K Long., 31° 13' 

 W., and not Ponta Delgada, San Miguel). 

 Elores is one of the northwestern islands of 

 the Azores and Delgada Pt. is its northmost 

 point. It would therefore seem from the posi- 

 tion in which the hottle was found that it had 

 approached the Azores from the north or 

 northwest. The hottle was of heavy glass and 

 closed with a paraffined cork. It contained a 

 Canadian postcard, offering a reward to the 

 finder who wrote on it the time and place of 

 finding. Set out at the same time were 99 

 other similar bottles and they were set out in a 

 line from Point Lepreaux to Gulliver Hole, on 

 the Nova Scotia Coast. A bottle set out about 

 a mile away from the one found in the Azores 

 was picked up on Cape Cod. 



Prom the known drift of other bottles in 

 the Gulf of Maine it seems probable that the 

 bottle which was returned from the Azores 

 passed southwestward in the Gulf of Maine 

 and passed' Cape Cod into the Atlantic and 

 further that the bottle took about two and one 

 half months to reach the water near Cape 

 Cod. Without doubt the bottle encountered 

 the " Gulf Stream " and was carried across it 

 to its eastern and southern side as the " Gulf 

 Stream" swings round the North Atlantic. 

 The time taken by the bottle to go from the 

 American coast to the Azores was probably 

 not more than nine and one half months. 



It is interesting to compare the drift of this 

 bottle with that of one recorded in the To- 

 ronto Daily Star, November 1, 1920.- 



A bottle cast into the Atlantic Ocean near New- 

 fotmdland by Sergeant D. Mclnnes, of Edmonton, 

 wlien returning to Halifax, September, 1919, after 

 shooting at Bisley, reached Nieuport, Belgium, 

 last August. 



This bottle undoubtedly traveled in the 

 western and northern edge of the " Gulf

Stream " and took about the same time to 

 cross as the other bottle. 



The drift of these bottles may be further 

 compared with the drift of derelicts^ in the 

 North Atlantic and especially with the well- 

 known drift of the schooner Fannie E. Wol- 

 ston which was adrift for at least two and a 

 half years and was observed over thirty times. 

 She was observed at sea in Lat. 36° N., Long. 

 74° W. (northeast of Cape Hatteras) on De- 

 cember 15, 1891, and four times afterwards on 

 her way across the Atlantic in an easterly di- 

 rection until she reached Lat. 35° N. and Long. 

 39° W. on June 13, 1892, having drifted in the 

 six months about four fifths of the way from 

 the American coast to the Azores. After 

 reaching this point she circled in the Sara- 

 gasso Sea and returned by a southern route to 

 the American coast.

AN ADJUSTABLE EMBOUCHURE 



To THE Editor of Science: I am much in- 

 terested in Professor Barus's article on "An 

 Adjustable Embouchure" (which the types 

 have made " embouchuer ") appearing in 

 Science for January 14, which has just come 

 to hand. I think he did not see my instru- 

 ment, exhibited at the meeting' of the National 

 Academy of Sciences and at the meeting of 

 the American Physical Society in 1919, which 

 I less modestly called " an artificially played 

 brass instrument," and which I claimed worked 

 exactly upon the principle of the human lips. 

 except that it lacked their softness. In it a 

 li^t piston, like a safety valve, with mass like 

 the lips, was lifted from its seat by the air 

 pressure, letting a puff of air into the wind 

 instrument, while the potential energy (elas- 

 ticity of the lips) was furnished by a wire 

 under adjustable tension. The pulse being re- 

 flected at the mouth of the horn (see my 

 paper in Proc. Nat. Acad. Sci., July, 1919) 

 comes back, and if it arrives in the right place,
