was no doubt that these tapestries are the work of lepidopterous larva? 

 which feed upon grain, the presumption being that they are made by 

 the larva? of what has been called the Mediterranean Grain or Flour 

 Moth (Ephestia kuhniella). The speaker briefly reviewed the history 

 of this insect and its injuriousness in various parts of the world, and 

 quoted from a report of Dr. Bryce, showing that in Canada, where it 

 became established in 1889, " a large warehouse, some 25 feet wide, 75 

 feet long, and four stories high, became literally alive with moths in 

 the short course of six months." — William Trelease.

New York Academy of Science, Biological Section.— Jan- 

 uary 13th, 1896.— The papers presented were : G. S. Huntington on 

 " The Visceral Anatomy of the Edentates." The characters of the brain, 

 alimentary, respiratory and genito urinary tracts were especially con- 

 sidered. The following forms were discussed : Myrmecophaga jubata, 

 Tamandua b i r i '" t-i. A ■■ r !,>>■,.•> didactylus,Dasypussexcinctus. T<dusia 

 iemtdata. In the brain characters the follow- 

 ing features were considered ; — the transverse frontal sulcus, the great 

 longitudinal fissure, and the absence of a distinct Sylvian fissure. In 

 the alimentary tra ci the ^loths are to be sharply separated from the 

 remaining groups, the stomach structure with its pyloric gizzard not- 

 ably aberrant: the ileo-colic junction is traced throughout the edentates 

 in a well marked series of transitional forms. 



O. S. Strong, " On the Use of Formalin in Injecting Media." The 

 paper made especial note of the advantages possessed by this preserva- 

 tive in injecting the brain in situ. Formalin (40 per cent formalde- 

 hyde^ diluted with an equal volume of water is injected into the ceph- 

 alic vessels until it runs from the cut jugulars. After a few minutes 

 the same quantity is again injected and once or twice again after an 

 elapse of fifteen to twenty minutes. The brain is then removed and 

 will be found to be completely fixed throughout. The swelling usually
