Barometric Observations. 



315 



P. S. — Since we had the honour of drawing out the preceding 

 statement for your inspection, Mr. Molyneux has declared to 

 Mr.Frodsham, in the presence of a third person, " That he never 

 did see the chronometers we sent out with Capt. Parry," but still 

 considers himself the maker for the following reasons, viz. that 

 a Mr. Hopkins had sprung tliem, who he said was his (Moly- 

 neux's) workman, and that he considered work done by tlie 

 workman, done by the master. In this principle we agree, pro- 

 vided the work is done under the inspection of the master, but 

 not otherwise. But we never did consider Mr. Hopkins in the 

 exclusive employment of Mr. Molyneux; and even if he were, 

 the person.who springs a chronometer cannot be regarded as the 

 maker, though it is an essential part of the work; for in this case 

 no master would be entitled to credit for his chronometers, as it 

 is the general practice to employ workmen to spring them ; and 

 Mr.Molyncuxdoes the same thing. The practical masters (amongst 

 whom we rank ourselves) finally adjust them, and without making 

 their final adjustments we could not deliver them with confidence. 



Mr. Hopkins receives only half the price for springing our 

 chronometers, that he is paid by other watchmakers who depend 

 entirely upon him to complete theirs. 



BAROMETRICAL OIJSERVATIONS. 



Crumpsall, Lancashire, April 10, 1821. 

 Sir, — I send you observations made at this place on Monday 

 the 9th instant. 



Mr. Thomas Hanson, of Manchester, having favoured me with' 

 his observations of the sart'e date, I transmit them to you with 

 my own. 



Mr. Hanson resides in Bridge-street, and his barometer, which 

 like mine is a common upright one, is four feet from the pave- 

 ment, and about eight feet higher than the bridge at the bottom 

 of the street ; which, as I have before stated, is exactly 28 (eet 

 above the level of the river Irwell. 



I am, sir, your obedient servant, 

 To Mr. Tilloch. ' John Blacmvali..
