the hen and chickens, are, on account of 

 their size, exempt from the effects of this 

 peculiar fault in Mr. Ward's style ; and 

 the consequence is that they are capital. 

 No. 338. Scene in the Play of Charles 



XII. G. Clint. A. R. A Two portraits 



at once so like, yet so unlike, as those of 

 Listen and Farren, as Adam Brock and 

 Charles XII., we have rarely seen, except 

 from the pencil of the same artist who pre- 

 sents us with these. In fact, we know of 

 no other painter who so invariably catches 

 the exact lineaments of the person he 

 would represent, and misses the spirit and 

 character of which those lineaments are the 

 types and interpreters It is true he rarely 

 paints any but actors and actresses a class 

 of persons whose faces, for the most part, 

 " have no characters at all," but consist of 

 lineaments merely like a mask. This kind 

 of practise may do much to dull the deli- 

 cacy of perception which is so essential to 

 the portrait-painter in particular. In other 



respects, this piece is among the most suc- 

 cessful of Mr. Clint's productions. 



We do not find any other new pictures 

 in this collection a detailed notice of which 

 could justify us in transgressing our limits 

 further. We will add, however, that Mr. 

 S. Davies has a very clever and attractive 

 picture of " The Interior of the British 

 Gallery" (as it appeared last year we be- 

 lieve) ; that Mr. Rippingill has an elabo- 

 rate scene in which much humour and skill 

 are wasted upon an impracticable subject 

 " Pilgrims approaching the Shrine ;" 

 (420) and finally, that Mr. Parris, the 

 artist to whom we are chiefly indebted for 

 the noble Picture of London at the Colos- 

 seum, has a very pleasing and highly 

 finished little picture called " The Bride- 

 maid" (494), which shews that he is capa- 

 ble of excelling in no ordinary degree in 

 the most pleasing and popular department 

 of his art that of scenes of sentiment and 

 character from domestic life. 



VARIETIES, SCIENTIFIC AND MISCELLANEOUS. 



Substitute for Wheaten Flour. A me- 

 dical gentleman, named Gouldson, residing 

 near Manchester, has discovered a mode 

 of separating and preparing the farinaceous 

 parts of such bulbous roots as turnips, car- 

 rots, parsnips, beet, &c., and of converting 

 it into fine flour. After a great variety of 

 experiments, carried on with perfect success 

 for nearly two years, this gentleman has 

 obtained a patent for his process which, if 

 his report is in every respect correct, and 

 that he really does produce good and nu- 

 tritious bread, equal both in quality and 

 colour to the purest white wheaten bread, 

 which is positively asserted, the discovery 

 may be considered to be of incalculable 

 value, for the quantity of farina to be ob- 

 tained fron the roots grown upon any given 

 quantity of ground, compared to that pro- 

 duced from the ears of wheat upon a similar 

 space, must be greatly increased the pa- 

 tentee says, twenty times at least. 



Kneading Dough by Machinery In 



large baking establishments the kneading 

 of dough for bread or biscuits is attended 

 with very great labour, and being performed 

 by the hands and sometimes by the feet of 

 men not particularly attentive to cleanliness, 

 a convenient mechanical substitute for the 

 manual labour of kneading must, in every 

 point of view, be desirable. It is not a 

 little remarkable that at this time there are 

 recently import d from Paris no less -than 

 four differently constructed kneading ma- 

 chines, some of which have, and the others 

 are expected tj) become the subjects of 

 patents in this country. 



Captain Kater's Collimator A parti- 

 cular degree of ill fortune seems to attend 

 certain individuals. Doctor Pearson, the 

 respectable treasurer of the Astronomical 



Society, invented and perfected a rock 

 crystal micrometer which had previously 

 been invented, used, and rejected in Paris. 

 Captain Kater, by a mechanical process, 

 arrived at his convertible pendulum ; Pro- 

 fessor Bohnenberger, of Tubingen, had 

 projected the same instrument from the- 

 oretical considerations fifteen years before. 

 Another invention of Captain Kater, which 

 some individuals have injudiciously consi- 

 dered as entitled to a medal from the Astro- 

 nomical Society, the floating collimator, 

 both vertical and horizontal, is an invention 

 of this same Professor Bohnenberger, of 

 Tubingen, and in a form upon which our 

 countryman has not yet stumbled, has been 

 used by Professor Gauss for several years, 

 and produced the most beneficial results. 

 In this case the telescope itself is its own 

 collimator and a coincidence effected be- 

 tween the wires in its focus and the image 

 of those wires as seen through the telescope 

 in a vessel of mercury placed immediately 

 under it. To effect this a piece of parallel 

 plate glass is placed at an angle of 45 be- 

 tween the lenses of the eye piece, and re- 

 flects the light of a lamp admitted through 

 an aperture in the side of the eye piece 

 down upon the wires and also upon the 

 mercury, while at the same time, from the 

 sides of the glass being parallel, there is no 

 obstacle to direct vision through it of the 

 wires and the reflected image of them. 



Rapidity of the Circulation of the 

 Blood A solution of ferruretted hydro- 

 cyanate of potash, introduced into the jugu- 

 lar vein of a horse, entered the circulation 

 and arrived at the opposite jugular in an 

 interval of from twenty to twenty-five 

 seconds. It arrived in twenty-three to 

 thirty seconds in the opposite external tho-
