The following Note hy Dr. Oldham has been handed to me 
by Colonel Strachey. It is but just to Mr. Theobald to 
observe, that unless Dr. Oldham has privately communicated 
the Note to him, of which I am not aware, he has had no op¬ 
portunity of knowing and replying to Mr. Oldham's remarks. 
<c In the preceding pages, several references are made hy 
Mr. Salter (pp. 51, 54, 58) to a small part of the collection of 
fossils from the Spiti Yalley, belonging to the Geological Survey 
* As tlie present publication will terminate my part in the discussion, I 
will describe at more length than I have hitherto done, the circumstances 
under which Dr. Gerard’s fossils were found by me in the Asiatic Society’s 
Musuem. The specimens figured in the Asiatic Researches were (except 
in one or two cases in which specimens were labelled in ink as from 
the Himalya,) my only guides to the genuineness of the collection. These 
were found partly on the shelves of a small wall case, partly in an old 
box without label, the other contents of which were a large number of 
A. communis and A. bifrons with a few of A. concavus and A. Thouar- 
sensis, also some other specimens of Ammonites, cfc., which last, although 
unlabelled and unfigured, the peculiar black geode matrix and conservation 
indicate, with little room for doubt, as from the Himalya, All these were 
mixed indiscriminately. They bore no label and the wrapping paper (if there 
had ever been any around them,) had entirely disappeared. There were no 
other fossils in the box (so far as I remember); certainly no other Whitby 
species than those figured in the Asiatic Researches and A. Thouarsensis. 
There did not seem, therefore, to be any a priori reason for doubting that the 
specimens in the box formed the bulk of Dr. Gerard’s collection, from which 
a few specimens (not by any means all of those figured) had been put out in 
the wall case. Since the publication of my paper, in hunting through the 
Asiatic Museum, I have found a large additional number of fossils, which, 
from their specific and lithologic identity with [now] described Himalyan 
fossils, I infer to have also formed part of Dr. Gerard’s collection. These 
were partly in a case of miscellania, (mixed with European and Australian 
fossils &c ,) partly in a box mixed up with Palaeosoic fossils from Van Dieinan’s 
Land and New South Wales. I have not, however, described these, as 
Dr. Stoliczka is engaged on the description of his more perfect series, and 
he will utilize the Society’s fossils so far as they are of any value. 
There is some difficulty in recognizing the originals of certain of Mr. 
Everest’s figures in the As. Res., but those of A. concavus, fig. 7, A. helero- 
phyllus, fig. 9, and Pecten cequivalvis, fig. 20, have been satisfactorily 
determined. There are two or three specimens, any one of which might 
have been the original of A. communis, fig. 5, and of A. bifrons, fig. 6.
