good and savoury. Passing lately over this Sea at a time, when it blew 

 a fresh gale of wind, and observing the water as above-described. I 

 took up some of it in a Glass-vessel, which having view'd the next day, 

 I found moving in it several Earthy particles, and some green streaks, 

 spirally ranged, after the manner of the Copper or Tin-worms, used 

 by Distillers to cool their distilled waters ; and the whole compass of 

 each of these streaks was about the thickness of a man-hair on his 

 head : Other particles hat but the beginning of the said streak ; all con- 

 sisting of small green globuls interspersed; among all which there 

 crawled abundance of little animals, some of which were roundish; 

 those that were somewhat bigger than others, were of an Oval figure : 

 On these latter I saw two leggs near the head, and two little fins on 

 the other end of their body : Others Avere somewhat larger than an 

 Oval, and these were very slow in their motion, and few in number. 

 These animalcula had divers colours, some being whitish, others 

 pellucid ; others had green and very shining little scales ; others again 

 were green in the middle, and before and behind white, others grayish. 

 And the motion of most of them in the water was so swift, and so 

 various, upwards, downwards, and round about, that Î confess I could 

 not but wonder at it. 1 judge, that some of these little creatures were 

 above a thousand times smaller than the smallest ones, which I have 

 hitherto seen in chees, wheaten flower, mould, and the like.« 



In den älteren Briefen Leeuwenhoek's ist von diesen Animal- 

 culis noch nicht die Rede; Anfang September 1674 scheint also 

 die Entdeckung der microscopischen Lebewesen, welche damals nur 

 unglaubliches Staunen erregte, gemacht worden zu sein. Die Beobach- 

 tung derselben in liegenwasser Avurde dann Mitte September 1675 

 wiederholt, wie sich aus den Phil, trans., XII, 133, p. &26 und aus 

 einem ungedruckten Schreiben an C. Huygens vom 7. November 1676 

 ergiebt. Doch sind wir damit wieder auf bekanntem Boden angelangt;

 behalf of the Rev. H. A. Macpherson) a specimen of the Isabelline Chat 

 [Saxicola isabeUina] shot in Cumberland, being the first recorded occurrence of 

 this species in Great Britain. — Prof. Bell, F.Z.S., exhibited and made re- 

 marks on specimens of the tegumentary glands from the head of the Rocky 

 Mountain Goat [Haploceriis montanus). — A communication was read from 

 Prof. H. H. Giglioli, C.M.Z.S., and Count T. Salvadori, C.M.Z.S, con-
