Magnetical Experime?its ; also, an excellent Liquor. By Mr. Colepress. 



N' 27, p- 502. 



I took an unpolished loadstone, which attracted but weakly ; and heated 

 a lath nail glowing hot, nimbly applying the north-pole of the said magnet to 

 it, which quickly took it up and held it suspended a great while. I took the 

 same stone and cast it into the fire, letting it remain there till it was thorough 

 hot ; I applied the north-pole to another lath nail cold and untouched before, 

 which it took up, but faintly, yet held it suspended for some time. Two or 

 three days after, I took the same loadstone, and found that it attracted then 

 as strongly as before it was cast into the fire. Whence I inferred, that the fire 

 somewhat lessened its attractive faculty, but did not deprive the stone of it. 



The liquor announced is a composition of the juices of good cyder apples 

 and mulberries, producing the best tasted and most curiously coloured liquor.

II. Disquisitio Anatomica de Formato Foetu ; authore G. Needham, M. D. 

 London, 8vo. An Anatomical Inquiry into the Formation of the Embr)-o or 

 Foetus ; by Walther Needham,* M. D. 



This disquisition consists of seven chapters. 



In the first he inquires into the passages by which the nourishing juice is 

 conveyed to the womb of the animal ; where he examines the assertion of 

 Everhard, importing that some of the lacteal vessels carry the said juice to the 

 uterus ; which vessels are pretended to have been seen by himself in the dis- 

 section of rabbits. Which engaged our author to take up again the anatomical 

 knife, and to dissect with all possible accuracy not only some of the larger 

 animals, as cows and mares, but some of the smaller kind also, such as rabbits, 

 which are instanced by Everhard. 



But having spent all his labour and care herein in vain, and besides evinced 

 by ligatures, that the pretended vessels are neither those that are described by 

 Bartholin, under the name of lymphatic, nor others presumed to be known 



• "W. Needham was an excellent English anatomist, and distinguished himself greatly by tlie work 

 of which an account is here given. Further particulars respecting this author's anatomical discoveries 

 may be seen in the 3d vol. of Birch's History of the Royal Society.
