156 DR. BENJAMIN ALLEN, OF BRAINTREE. After this, Allen seems to have made no further communica- tions to the Royal Society for some twenty years ; but, in the same year (1699), he published his first scientific work entitled : The / Natural History / of the / Chalybeat and Purging Waters / of / England, / with their particular / Essays and Uses ; / among which are treated at large / the / Apoplexy and Hypochondriacism : / To which are added / Some Observa- tions on the Bath / Waters in Somersetshire. / Dedicated to ths Right Honourable the / Earl of Manchester. / By Benjamin Allen, Med. Bac. / London : / Printed and Sold by S. Smith and B. Walford, at the Prince's Arms in St. Paul's Churchyard, 1699. The book appeared under good auspices, for it was issued by Messrs. Smith and Walford, "printers" (that is, publishers) to the Royal Society. The Earl of Manchester,1 to whom it was dedicated, seems to have been Allen's patron and employer in some way, as will be seen hereafter. Allen's book was practically the earliest systematic treatise on the medicinal waters of England, and is of special local interest, inasmuch as it describes no fewer than eight Essex springs. Though as valuable as any work of the kind and period could well be, it was a very poor production from the literary point of view. The punctuation is extremely bad and the diction often so confused as to be incomprehensible. This was due, no doubt, to the fact (of which Allen tells us in his preface) that it was written largely whilst he was a young undergraduate at Cambridge. That Allen himself was well aware of its imperfection is clear from his apologetic explanation2 that he was obliged to excuse the whole discoursive part of the book, and particularly the impertinences and imperfections of it, being only casual and written raptim ; and much of it [was] never read over by me till printed and [my remarks] were designed but as hints . . . ; sa that the great precipitation, with the impediments, made much or all of it so far from being exact as to be thoughtless almost. Elsewhere he says3:— My account of the reason of the operation of the waters is so wild and imperfect as to be nauseous to myself and [to] afford me no other satisfaction than that I have hinted what ought to be done [in the way of investigation]. Explaining "why I publish anything so loose and inaccurate," he continues4:— I can only say that the discourses (which were written off hand) had not the leisure for thought that the experimental part had (which was, in good measure, 1 Charles [Montagu), 4th Earl and first Duke of Manchester, an eminent diplomatist, was born in 1662 ; succeeded to the earldom in 1683 ; was created a duke in 1719 ; and died in 1722. 2 Op. cit., Preface, p.
