the finger which had been divided had as much sensation as any 

 other part of the body. The dressing was continued, and in three 

 more days the re-union was complete *. 



15. SINGULAR EFFECT OF OPIUM. 



M. Cavalier states that he had used an enema, consisting of two 

 ounces of mucilage and a grain and a half of opium. He was 

 seized with nausea, but "no vomiting ; but having removed the cover 

 of the night-lamp, the appearance of the light produced vomiting, 

 and this increased whenever he submitted to the action of light. 

 He endeavours to explain this curious phenomenon, but leaves it as 

 obscure as he found it t. 



16. MECHANICAL POWERS OF A SPIDER. 



The following description of the capabilities and power of a small 

 species of spider, supposed to be the Aranea extensa, is given by the 

 Rev. Mr. Turner, in the Transactions of the Northumberland Natural 

 History Society: it was shown to him by Mr. Mackreth ' On call- 

 ing upon him (Mr. Mackreth) the next morning, he brought out a 

 tumbler glass, which he had inverted on the table over a sprig of 

 Laurustinus bush, on which he had observed a very small spider. 

 Supposing that it might want air, he had slipped under the edge of 

 the glass a small roll of paper. In less than three days, the little 

 animal had filled the interior^of the glass with minute, almost invisible 

 threads, by means of which it had raised the sprig into the middle of 

 the glass ; and, not content with this, had raised also the coil of 

 paper which by some accident had slipped from under the edge. After 

 this, it laid, upon one of the upper leaves, a large ball of eggs, and 

 having thus completed the ultimate object of its existence, it died, 

 and fell into the meshes of its own web. 



4 How this little artist should have accomplished the Herculean task 

 of raising a weight several hundred times greater than itself, and for 

 what purpose it should have done this, are questions which may well 

 deserve consideration. 



4 From a comparison of the individual inquestion with the very few 

 figured by Donovan, it appears to be most like the Aranea extensa, 

 vol. viii. p. 48 ; and as it is there said to be always found upon trees, 

 and never upon the ground, this may be the reason why it has exe- 

 cuted the arduous task of raising the branch, on which it was confined, 

 to the upper part of the glass J.'

Mr. Yarrell has made several attempts to preserve white bait alive, 

 of which the following are the results :
