17G Miscellanies. 



dispatch. Still, it is desirable that the stock of talent, skill and ma- 

 teriel in this department should be increased, and we trust that the 

 very respectable men already established in this line, will welcome 

 to this country one who has long been celebrated in his own. 



Mr. John Millington, civil engineer and machinist, and late pro- 

 fessor of Mechanics in the Royal Institution, and of Natural Philoso- 

 phy in Guy Hospital, London, has established himself at No. 207, 

 Pine street, Philadelphia. The collection of apparatus and sub- 

 stances, specimens and various means of experiment, research and 

 illustration, enumerated in the printed sheet of Mr. Millington, in- 

 cludes almost every thing that is needed, both by those who teach 

 and by those who learn. 



Mr. M. is also a practical machinist, architect and manufacturer, 

 and proposes to furnish models, machines, substances, instruments, 

 instructions, and every thing needed for a successful prosecution of 

 the practical arts as well as of science. We trust that this country 

 is wide enough both for him, and his coadjutors in. the same impor- 

 tant pursuits, and that all of them will find encouragement to con- 

 tinue and enlarge their establishments. We have formed a very fa- 

 vorable opinion of Mr. Millington from his papers in the English 

 Quarterly Journal of Science.

 back over his whole body, the intersections of which give the-math- 

 ematical figure of the diamond or rhomboid. The lines are smallest 

 where the diameter of the body is least, and on the largest part do 

 not exceed the fourth of an inch in width. The body of the snake is 

 of a light brown or copper color; the stripes are a light yellow, and 

 at each extremity the color is darkest. 



This rattlesnake is the largest reptile in this part of America*. It 

 is often eight feet long — skins of the largest size, when stripped from 

 the body, have held three pecks of sand. Three, of °reat size, were 

 killed during the past summer on the waters of the little Tala- 

 poosa ; one of them had fifteen shells to his rattle. The Rev. Mr.
