ral faithful; and if there is wanting that accuracy which modern improvements have rendered necessary, in delineating the more minute parts, yet, upon the whole, the figures are sufficiently distinctive of the subjects. The style of the engravings is what would now be called hard, but it is fully on a level with the prevailing taste of the age; and, as a piece of labour, executed, it would appear, in the space of four years, by the hands of one woman, the whole work is entitled alike to our wonder and admiration. While Mrs Blackwell was proceeding in her task, she attracted the attention of many persons of eminent rank and character, and also a great number of scientific persons, who visited her at Chelsea, and afforded her many marks of kindness. On the completion of the first volume, she was permitted in person to present a copy to the College of Physicians, who acknowledged her extraordinary merit by a handsome present, as well as a testimonial, under the hands of the president and censors of the institution, characterising her work as "most useful," arid recommending it to the public. It seems to have been at this period of her labours, that, after having all along supported her family by her own exertions, she was enabled to redeem her husband from confinement
Blackwell, after his release, lived for some time at Chelsea with his wife, and, on her account, was much respected. He attempted to perfect himself in the study of physic, and also formed schemes for the improvement of waste lands. This latter subject he studied to such a degree, as to be enabled to write an agricultural treatise, which attracted some attention. Among his other occupations, for some time, was a prosecution which he entered into against some printsellers, for pirating his wife's botanical plates. By his success in this affair, he revenged in some measure the persecution to which he had been subjected for his inadvertent breach of another exclusive law. His agricultural knowledge gradually became known, and he was often consulted on difficult points connected with that science, and received handsome fees for his trouble. At one time he was employed by the Duke of Chandos in superintending some agricultural operations at Cannons. His work on agriculture, which was published at this time, recommended him to the attention of a still higher patronage the Swedish ambassador, who, having transmitted a copy to his court, was directed to engage the author, if possible, to go to Stockholm. Blackwell accepted this engagement, and sailed for the Swedish capital, leaving his wife and one child in England, with a promise that he would soon send for them. He was received in the kindest manner at the court of Stockholm, was lodged in the house of the Prime Minister, and was allowed a pension. The king of Sweden happening soon after to be taken dangerously ill, Blackwell was permitted to prescribe for him, and had the good fortune to effect a cure. He was consequently appointed one of the Icing's physicians, and styled Doctor, though it does not appear that he ever took a degree in medicine. While enjoying all this good fortune, he was not forgetful of his wife, but sent her several sums of money, and she was on the point of sailing to join him at Stockholm, when all his prospects, and life itself, were overwhelmed at one blow. It is probable, from the character of his brother Thomas, that he was a fervent admirer of the principles of civil liberty. Nothing, moreover, can be more probable than that a man, accustomed to all the freedom of speech which is so harmlessly permitted in Britain, might not very readily accommodate himself to that prudence of the tongue which is demanded from the subjects of an arbitrary monarchy. It is at least certain, that he was apprehended on suspicion of being connected with a plot, which had been formed by one Count Tessin, for overturning the constitution of the kingdom, and altering the line of succession. Being put to the torture, he is alleged to have confessed a concern in this conspiracy. Every reader, how
