By M and R Gordon

Comments Off

A rare example of Soresi’s arm-to-arm transfusion apparatus, for which he held two patents (see links below): one issued in 1924 and the other in 1925. Unlike the Braun apparatus, which was produced in large quantities for the German military during WW2),and which we see frequently offered on the Internet , the Soresi apparatus was not widely used by the US military and few examples seem to have survived. The one we are offering is largely complete, as a Read More...

That the instrument is made of untreated brass, the case is made of mahogany and the no. 352, indicates that it is a very early instrument. Felt has not yet been used. The stadimeter or optical range finder, was developed in the 1890s by Bradley Allen Fiske and designed to determine the distance to other warships. Like a sextant, Read More...

Dr. Butler’s 1881 Patent Electro-Magnetic Device for Medical Use

By M and R Gordon

Comments Off

Dr. Butler’s Patent “Electro-Magnetic Device for Medical Use” was granted a US patent on February 1, 1881. ( pat. 237,167)–see last image. This example appears to be working but it would benefit from a little loving care. There is also a superb example of this device on Fleaglass but there is a very substantial price difference between the two. Our example is probably bit earlier, as evidenced by the fact that handle is as shown in the patent drawing. Read More...

Edison invented the electric bulb in 1879. A few years later (c1883) a doctor in Brooklyn NY, R.W. St. Clair, introduced what has been described as the first small electric lamp to be used in surgery (The Medical Summary, Vo. 10, June 1884:76). https://www.google.com/books/edition/The_Medical_Summary/9H2-z5et6yEC?hl=en&gbpv=1&dq=The+st+clair+electric+lamp&pg=RA3-PA76&printsec=frontcover While most often used in the examination of the throat it had other applications as well. We are offering a scarce and complete example of this instrument–the power source was a battery that presumably was sold separately. Read More...

A late 19th-century esthesiometer

By M and R Gordon

Comments Off

A late 19th-century esthesiometer , likely a variant of Sieveking’s model, similar to the one used by Cesare Lombroso in his influential study “Criminal Man” (1876)–see third image, which is taken from his book. Lombroso believed that criminals had a higher threshold for touch and pain. Using an esthesiometer, and other devices, he claimed to have confirmed this. Esthesiometers are currently part of the neurologist’s armamentarium. In very good cosmetic and mechanical condition. Quoting from Wiki: “An esthesiometer (British spelling aesthesiometer) is Read More...
