bled from the arm and temporal artery, had leeclies applied to the 

 scalp, blisters to the nape of the neck, and took calomel so as to render 

 his gums sore. Finding that no eff'ect whatever was produced by 

 these measures, I gave up the expectation which I had at first enter- 

 tained of his recovering sight, but was resolved to give the remedies 

 a complete trial. I ordered him to be bled, ad deliquiuin. This 

 took place after a small quantity of blood had flowed from his arm 

 while he was in an erect posture. After a few days, he was still 

 perfectly dark. An incision was now made over the sagittal suture 

 ffom the forehead to the occiput. It was filled with peas. In three 

 or four days, precisely at the time when suppuration began to take 

 place, the patient declared that he perceived light, but was scarcely 

 believed, since the pupils were still widely dilated and quite insensible 

 to a strong light. In the course of a few days it was quite evident 

 that he saw, as he could tell when two or three fingers were held up. 

 For some weeks, the iris was still quite irritable, though vision had 

 become in a great degree restored. 



The subsequent treatment of the case consisted chiefly in occasional 

 leechings, purging, and low diet ; when the issue healed which was 

 not till it had been kept open some months, a seaton in the neck was 

 substituted ; under this treatment the case has terminated in a com- 

 plete recovery of the blessing of sight. I shall not detain the 

 medical section longer upon this topic, but have procured the presence 

 of the patient, and any gentleman who wishes to examine him, 

 either as to the accuracy of what I have related, or to the degree of 

 suffering occasioned by the remedy, or to observe the slight vestiges 

 which it has left, will have an opportunity. 



II. — Death of Dr. Henry of Manchester. 



It is with painful feelings that we announce the death of this excel- 

 lent man — more particularly from the melancholy circumstances 

 under which it took place, and from the daily communication which 

 those interested in chemical pursuits held with him, during the 

 meeting of the Bristol Association, where he took an active part. 



Dr. Henry finished his education in the university of Edinburgh. 

 To this College he manifested through life a great attachment. 

 During his studies in that celebrated establishment, he was exceed- 

 ingly fortunate. He attended the lectures of the illustrious Dr, 

 Black, one of the fathers of chemistry ; and he was the associate 

 and friend of Brougham, of JeflPrey, of Mackintosh, and a number 

 of others, who have since attained, like himself, a high degree of 

 celebrity. Lord Brougham in his address to the Manchester Me- 

 chanics' Institution, in 1835, referred to Dr. Henry in the most 

 respectful terms as a fellow student. " I met," says he, '* an old 

 and worthy friend of mine, a man of great ability and learning, your 

 townsman. Dr. Henry. We were fellow Collegians, and learned 

 Chemistry together — though, God wot, he learned a great deal more 

 than I did." 



Dr. Henry was intended for the medical profession; but very 

 delicate health, and the necessity of his co-operation in his father's 

 lucrative pursuits, which he subsequently so greatly extended, in- 

 duced him, after some practice, to relinquish that arduous and har-
