The President exhibited a box of galls, which had been forwarded to him from 

 Germany, together with the makers of many of them, named in accordance with the 

 nomenclature adopted in Hartig's work on gall insects. One of the species was 

 Cynips Kollari, hitherto erroneously called in this country C. Lignicola. Of this spe- 

 cies the President remarked that about three years ago it appeared in the woods near 

 London, especially on the north side, in very large numbers ; but in the second year 

 of its appearance the tomtits had discovered that each gall contained a fine fat 

 grub, and the result was that it was now difficult to obtain a perfect gal!. Mr. 

 Walker corroborated Mr. Smith's account both of the appearance and the approxi- 

 mate extermination of the species in the woods near Highgate ; and Prof. Weslwood 

 expressed a hope that the fact would be made known as widely as possible, since it 

 aflforded an additional argument to the many already produced in opposition to the 

 indiscriminate slaughter of small birds. 



Prof. Westwood exhibited specimens of Acarus domesticiis, DeG. (A. Siro, Linn), 

 found by Dr. Maddox, of Woolston, Southampton, in a nitrate of silver bath prepared 

 for photographic purposes ; and suggested that Mr. Andrew Crosse's wonderful crea- 

 tion of Acari might probably be explained on the hj'pothesis that, in that case as in 

 this, the insects had been attracted by some of the chemical ingredients employed. 

 He also exhibited some photographs of insects sent to him by Mr. Dale, the execution 

 of which was so good that, notwithstanding a certain haziness, the specific distinctions 

 of even small species were recognizable: many of the insects ]>hotographed were 

 gummed on card, which spoiled the effect ; but when they were pinned high, and had 

 the wings flat and horizontal, the result was so successful that the Professor thought 

 that for large insects, and especially for Neuroptera, photography might well be 

 employed for the publication of figures ; but that for smaller species it would perhaps 

 only be useful in taking representations, from which the draftsman might afterwards 

 make magnified drawings. 



Prof. Westwood also exhibited a box of interesting objects recently contributed by 

 Mr. Stone to the Oxford Museum : amongst them were' some galls similar to those
