SAMUEL DALE AND THE DALE FAMILY. 61
neighbour, Dr. Benjamin Allen, of Braintree67), We find Dale
writing68 to one John Houghton, of St. Bartholomew's Lane
in London, an apothecary, and probably an old fellow-student,
about a certain Essex Mineral Spring, of which he had had ex-
experience, finding its water like that at Epsom, but more
active. He does not indicate its whereabouts; but, as he
says that it is referred to by Merrett in Ids Pinax, it was
probably that at South Weald, near Brentwood.69
Again, we find Dale writing,71 on 2nd December 1693, to
Dr. Martin Lister72 in reference to Conchology. He mentions
having called on Lister in London (doubtless with an intro-
duction from Ray), hoping to see his collection of shells, in
which hope he had been disappointed, as Lister was not at
home. Since then, Dale had sent Lister a copy of "my book"
(clearly the first edition of the Pharmacologia, then just out)
and had received from Lister one of his own works in return.
Dale, proceeding, says:—
"For some years past, I have had a curiosity of collecting English
shells and have sometimes thought [that], among those I have (which
are farr short of what you figure and describe to be of English produc-
tion), there are some which either you have not mett with or, at least,
I cannot make them out to be the same."
Accordingly, he sends to Lister "specimens of all the species I
have, of which I beg your acceptance," asking him for the loan of
a selection in return.
In Entomology, too, Dale was more or less expert, as we
learn from passages in the "Common-place Book" of his neigh-
bour, Dr. Benjamin Allen, whom he sometimes helped in the
naming of uncommon insects." Again, when Ray died, in
1705, leaving unfinished his great Historia Insectorum, Sloane
suggested to Dale that he should finish it. Dale's reply was
that, so far as English insects were concerned, he felt himself
equal to the task, but that foreign species were beyond his
powers.74
But nowhere is Dale's wide knowledge of natural objects
