Dear Sir
I have delayed answering your letter of the 4th until I could see Mr. Murray2. The only analyses of Globerigina ooze3 collected by the Challenger4 are to be found in the appendix to Sir Wyville Thomson[']s5 book on the Atlantic6. Mr. Murray tells me that other analyses have been made but are not yet published. Since March of 1877 I have had no connection with Challenger work whatever, I have [2] therefore not been able to make any analyses myself.
You will see from Mr. Brazier's7 analyses at the end of Sir Wyville Thomson's book that globerigina ooze, like other deep sea deposits is by no means a homogeneous substance, that in fact it includes mixtures of shell debris (calcareous matter) clay & sand in proportions varying between wide limits. Sand is no instance[?] of impurity in a deepsea [sic] deposit, in fact I think [3]8 that it is invariably an ingredient in deep sea bottoms no matter how distant the nearest land may be. In order to get information up to date you should apply to Sir Wyville Thomson or either directly or through Mr John Murray 32 Queen Street Edinburgh and it is not unlikely that he may be willing to supply it.
I remain | Yours truly | J. Y. Buchanan [signature]
