MEMORANDA. 113 



pose, troublesome or requiring fine workmanship ; and have 

 been led to invent more simple ones for their own use — thus 

 has it been with me. 



My clasp consists of a strip of sheet-brass {a, fig. 4), ten 

 inches by one half of an inch, and about as thick as stout 

 Bristol board ; indeed, so thick that it will bear the weight 

 of a two-ounce bottle without bending. Thi& is bent, as is 

 seen in the figure (4), and around it is wrapped another 

 piece of brass, so loosely that it will slide upon it. To the 

 end of the rod which is used for the purpose, is attached a 

 brass tube {b), the end of which is slightly turned over, 

 inwards. The bottle is now placed in the loop (c), and the 

 end {d) being brought down on a, the slide (e) is pushed up so 

 that it holds and clasps the bottle firmly. The spring part (/) 

 is now forced into the ferule [b), until the catch {g) holds it in 

 its place. When it is wished to remove it, we have but to 

 press the spring-catch at h, and it can easily be taken out of 

 the ferule. 



I ofier these remarks with much readiness, and shall be 

 pleased if you deem them worthy an insertion in your valua- 

 ble periodical. — Arthur M. Edwards, College of Physicians 

 and Surgeons, New York City, U.S., October 20th, 185G.
