In consequence of the frequent depradations and disturbances in this town and neighourhood, a few of the inhabitants have raised a subscription, and procured a policeman from London, who commenced his duties on Saturday last. The appointment, so far, seems to augur well; and it is hoped that a great improvement in the peace and good order of the town will be the result.

On Wednesday, the 21st, as Captain Puckey of St Blazey, the mine managing agent of J.T. Treffry Esq., was performing his round on horseback, on his way to Par Consols, in the West Fowey Consols Mine, and whilst riding along the towing path of the canal (from Par to Pontsmill) his horse took fright at the flapping of some clothes which had been put out to dry, and instantly leaped with his rider over the slopping part of the canal into the water. Capt. Puckey says that in coming out of the water he found a difference in the atmosphere equal to that of the deep level in Fowey Consols Mine, which he had only left about three hours before.

On Saturday last, a gold laced hat was presented by Captain Puckey, Mr Treffry's principal mining agent, to Simon Uren, timberman, of Par Consols mine, in the presence of three hundred men, for the diligence and superior workmanship he had displayed, particularly in Treffry's North Engine Shaft, which is considered not to be equalled in the county.

The Health of Towns Association having published returns of sickness and mortality in this county, have given among them a table showing the average age of all who have died in each registration district of the county. The returns were made in 1841, when the total population of the various districts was 343,310. The average age of all who died in the St Germans and Liskeard district, was 42 years 11 months; Bodmin and St Columb district 37 years 1 month; Launceston, Stratton and Camelford district, 33 years 9 months; Truro district, 33 years 4 months; St Austell district, 31 years 11 months; Helston district, 30 years 7 months; Penzance and Scilly Islands district, 29 years 2 months; Falmouth district, 29 years 1 month; Redruth district, 28 years 4 months.

Held before Joseph Hamley, Esq, Coroner on 18th inst at the Lunatic Asylum, Bodmin, on the body of Peter James, a patient who was found hanging in one of the water closets of the asylum. It appeared that the deceased was admitted as a pauper from the parish of Breage on the 20th of July last. He was of a very melancholy disposition and being considered a suicidal patient, was placed in the hospital gallery. On the evening he destroyed himself, he was removed into one of the new dormitories (where eighteen patients sleep, with a keeper in an adjoining room) to make room for another patient.

On the morning of the 16th, about four o'clock, one of the patients, named Lawry, had occasion to go to the water closet, where he saw a man, as he thought, sitting on the bench. He spoke to him but received no answer. He then called another patient, named Uren, who came and saw that deceased was suspended by his neckerchief to the window frame. He untied him and Lawry called Marshall the keeper, who came and immediately called Mr Tyerman, the superintendent of the establishment. On the keeper leaving deceased the night before, he (deceased) requested to be allowed to have his neckerchief, to put round his head, as he felt cold. This was allowed. and with this he suspended himself. Mr Tyerman said he was called by Marshall and found the deceased as before described; he tried every means to resuscitate him, but without effect, as he had been dead for too long a time. He considered deceased as a very melancholy patient, and liable to commit suicide. The jury returned a verdict that the said Peter James hung himself being of unsound mind.
