808 SUMMABY OF CURRENT RESEARCHES RELATING TO 



pins from the St. Elmo store is copied in No. 4. I was thus enabled 

 to assert that the pin found in Carpenter's buggy must have been 

 made in the same machine as those used by the girl just before the 

 murder. 



These pins were, moreover, of a peculiar pattern ; among eighty 

 packages purchased in Chicago and in Lincoln, and some twenty odd 

 hairpins obtained at random, I did not discover a single pin exhibiting 

 the same markings. The scarcity of pins of this pattern was after- 

 wards explained by the fact that the factory in which they had been 

 made was closed eleven years ago. The rarity of hairpins made in 

 this particular machine combined with the presence of one of them 

 found in Carpenter's buggy, rendered it highly probable at least that 

 the girl had ridden in this buggy." 



American Society of Microscopists. — The deputation (Dr. Dal- 

 linger and Mr. A. W. Bennett *) appointed to represent our Society 

 at the Eochester, N.Y., meeting of the American Society have not 

 yet returned from America, so that we are not in a position to give 

 any authentic report of the proceedings of the meeting, but we under- 

 stand from private sources that nothing could exceed the courtesy 

 and warmth with which the deputation were received by our American 

 brother microscopists, everything being done to testify to the friendly 

 feeling entertained for our Society on the other side of the Atlantic. 

 We are sure that Dr. Dallinger and Mr. Bennett did not leave un- 

 acknowledged at the time the courtesies extended to them, but the 

 appreciation of the Society at large will remain to be expressed at the 

 ensuing meeting, by which time it is anticipated that the deputation 

 will have returned. 



The toast of " The Royal Microscopical Society " was proposed 

 at a supper given to the American Society, and Dr. Dallinger was 

 elected an Honorary Fellow. 



Health Exhibition. — The connection of this exhibition with 

 health is, as is generally recognized, one of a very slender kind, and 

 it is to be regretted that such a department as the Biological Labo- 

 ratory, which in a true " health " exhibition would have occupied a 

 prominent place, is relegated to the comparative obscurity of the 

 topmost rooms of the lofty City and Guilds Institute. 



The laboratory is under the charge of Mr. W. Watson Cheyne, 

 M.B., who exhibits a large series of microbes of various kinds, isolated 

 and growing in the media suited to them. The laboratory contains 

 examples of fungi injurious to animals or plants, or altogether in- 

 nocuous; and it is well equipped with apparatus and appliances, 

 including incubators, sterilizers by steam and dry air, aspirometers, and 

 Microscopes ; there are also 36 photo-micrographs and some diagrams, 

 among the latter of which are those that illustrate the excellent 

 influences of vaccination and re-vaccination, and show that in later 

 years no German soldier has died of small-pox, and that in some 

 years only 2-12 in 100,000 have been ill of it. Many of the
