Extract

During the course of a general investigation by one of us (K. L.) of diamonds from various sources, using X-ray analytical methods, the inquiry arose as to whether so-called artificial diamonds had ever been examined in this way. It was found that there was, in the Mineral Department of the British Museum, a glass slide bearing 12 minute specimens, labelled as being diamond, artificially prepared and presented by Mr. J. B. Hannay in 1880, presumably the remainder of those investigated by Prof. N. Story-Maskelyne, and referred to in a letter to the Editor of The Times which appeared in that paper on February 20, 1880, as follows:

Sir,—A few weeks since I had to proclaim the failure of one attempt to produce the diamond in a chemical laboratory. To-day I ask a little space in one of your columns in order to announce the entire success of such an attempt by another Glasgow gentleman.

page 319 note 2 In Hannay's second paper these quantities are reversed, and have been so quoted subsequently by others, but it is clear from the context that only a relatively small percentage of bone-oil was actually used and that Hannay intended to give the figures as we have given them above.

page 323 note 1 The existence of extinction is the result of what the X-ray crystallographer calls crystal ‘perfection’. By this is meant a uniformity of internal structure, without the slight changes of orientation or position that exist between the component crystallites of a ‘mosaic’ crystal. A diamond may be ‘perfect’, in this sense, and yet show optical anisotropy, because of the existence of a uniform internal strain; or it may be ‘mosaic’, and yet optically isotropic because the individual crystallites are unstrained.
