THE LATE MR. CHARLES HAWKINS.

Charles Dickens' Consultation with Mr. Syme *The Life of Charles Dickens, by John Forster, page 417.

us believe) in any dialect in Scotland; in fact the tendency in all Scotch dialects is to pronounce it "jest." And as regards the alleged difference of opinion between Mr. Syme and Sir Henry Thompson, I heard Mr. Syme describe his interview with Dickens on the day it took place, and remember that he not only took a serious view of the condition of Dickens' foot, but also spoke of Sir Henry Thom...

The weak Hawkins-Simon Condition

A real square matrix satisfies the weak Hawkins-Simon condition if its leading principal minors are positive (the condition was first studied by the French mathematician Maurice Potron). Three characterizations are given. Simple sufficient conditions ensure that the condition holds after a suitable reordering of columns. A full characterization of this set of matrices should take into account t...

The Late Mr. John W. Davies

The virtues of the cortex in 1680: a letter from Charles Goodall to Mr. H.

CHARLES GOODALL (1642-1712) devoted his career to the affairs of the Royal College of Physicians of London and became its most articulate defender against attacks of seventeenth-century empirics and chemists.' In his The College of Physicians vindicated ...2 of 1676 he assailed the apothecary-empirics, particularly Adrian Huyberts for misrepresenting College licensing policies and the achieveme...

On twin primes associated with the Hawkins random sieve

We establish an asymptotic formula for the number of k-difference twin primes associated with the Hawkins random sieve, which is a probabilistic model of the Eratosthenes sieve. The formula for k = 1 was obtained by Wunderlich [Acta Arith. 26 (1974), 59 81]. We here extend this to k ≥ 2 and generalize it to all l-tuples of Hawkins primes.
