of tho bamboo filament lamps of 1880, and an original wooden-screw 

 socket for each type. The paper filament lamps, one of which is 

 intact, are of the first type made after the successful experimental 

 lamp of October 1879, and the bamboo filament lamps, one of which 

 is intact, are the first commercial type, Donald F. Poole, Washing- 

 ton, D.C., presented two early Maxim lamps mth sockets. A more 

 modern note in electric lighting is represented in a display panel of 

 eight rare gas discharge tubes, the gift of the Air Reduction Sales 

 Co., New York City. Two fans received show early stages in the 

 development of this electrical appliance. One, made by Leo Daft, 

 electrical pioneer, and dating from before 1890, is the gift of Mrs. 

 Matilda Daft Williams, Albany, N.Y. It is small, with an unguarded 

 fan wheel mounted on the shaft of a small motor with long vertical 

 field coils. The other is a Holtzer Cabot fan of about 1900, in which 

 the earlier type of motor and same general arrangement are still 

 evident though dressed up in a heavy cast-iron base and grilled 

 housing. This fan is the gift of Mrs. Mae I. English and Mrs. L. F 

 Speich, Washington, D.C. 



A Merritt typewriter of about 1890, one of the first few machines 

 made by the Alerritt Typewriter Co., Springfield, Mass., and a com- 

 mercial form of a machine formerly represented in the collection by a 

 Patent Office model only, was the only addition to the typewTiter 

 collection. It was presented by C. C. Merritt, nephew of the inventor. 



Two Edison phonographs were added to the collections. One, an 

 original of the tin-foil record type, was presented by Frank A. Ward- 

 law; the other, a nicely preserved "Amberola-50" of about 1915, the 

 gift of Clarence Beyer, Baltimore, Md., represents the final develop- 

 ment of the wax-cylinder record type, and is complete with a group of 

 select records. 



Among the additions to the collection of surveying and astronomical 

 instruments is the Herschehan reflecting telescope made by Amasa 

 Holcomb, of Southwick, Mass., about 1835. The reflector, about 8 

 inches in diameter and having a focal length of about 9 feet, is of 

 speculum metal and has a remarkably well preserved surface. It is 

 the gift of Mrs. Grace E. Holcomb Steere and Airs. Eva C. Holcomb 

 Storey, Southwick, Mass., who also presented an astronomical 

 transit and instrument tripod by the same maker. From the War 

 Department came an interesting form of large reconnoitering tele- 

 scope and an astronomical transit, both about 60 years old. 



Among the watches added to the timekeeping collections is an 

 English silver case watch dated 1794, the movement of which is 

 marked "Effingham Embree, New York." Not many watches in the 

 collection dating from 1800 carry the names of American makers or 

 importers. It is the gift of Mrs. Gertrude O. S. Cleveland, Quine- 

 baug, Conn. Clocks added to the collection include two tall case
