LIST OF CONTENTS
SECTIONS A - C RESEARCH AND LECTURES AT OXFORD UNIVERSITY 1928 - 1969
A. Cytology A.1 - A.52
B. Histochemistry B.1 - B.14
C. Microscopy and microtechnique C.1 - C.43
SECTION D PUBLICATION D.1
Dr. Baker was Reader in Cytology at the University of Oxford; he lectured regularly on several aspects of the subject and conducted research in cytological technique and the practical possibilities of different types of microscopy, with particular reference to the phase contrast and later the electron microscope. This material forms the bulk of the present collection and covers lectures and practical classes given to members of the university from 1928 to 1969, and the research data on which they were based. The lectures, which are all in longhand, show evidence of frequent and extensive revision, as do the duplicated typescript sheets for distribution in practical classes. In addition, the laboratory notebooks indicate very carefully the aims, techniques, methods and results of Dr.Baker's research, and experiments are frequently accompanied by reflections on the results, memoranda for alterations and revisions, or notes of new ideas to be tested and incorporated. Although many of the lectures are written out in full, Dr. Baker did not use the full text in the lecture room, but spoke from very short notes without using any memorized phrases.
After his retirement, Dr. Baker continued his research and lecturing, especially on electron microscopy. Item C.24 is a set of lectures for graduates on the construction and operation of the electron microscope, delivered in 1968 and 1969, while item C.25 is an experimental one-day course in electron microscopy for undergraduates, which he gave in 1969.
There are no correspondence files as such, but Dr. Baker kept a few letters of immediate scientific relevance with the papers to which they refer: see A.45, C.15, C.27.
Item D.1 consists of the autograph ms. of chapter 23 of Dr. Baker's book Race (London, 1974).



SECTION A CYTOLOGY  [no ref. or date]

Notebooks on laboratory research 1929-67  CSAC 69/7/79/A.1-A.17  [n.d.]

Arrangement: The notebooks were numbered from I to XVI by Baker and also dated by him. The first item in this Section (A.1) does not strictly belong under the heading of Cytology, but it has been included because it was kept by Baker with the Cytology notebooks.


Contents:
Although all the notebooks are labelled 'Cytology', the later ones contain a considerable body of notes on microscopy, particularly in relation to phase contrast microscopy (A.9 - A.12, A.16, A.17) and the function of the eye as an integral part of the light microscope (A.16, A.17). Baker used the first person extensively in describing experiments, commenting on methods and planning future work which makes the notebooks read more like a diary and contributes to their interest as an illustration of his methods of work.

Notes for lectures and practical classes 1928-66  CSAC 69/7/79/A.18-A.52  [n.d.]

Arrangement: The material is presented in chronological order as far as possible, and where a lecture has more than one date it is filed under the most recent one. Reading lists and lists of slides to be shown have normally been left with the lectures to which they apply.
Titles and descriptions in inverted commas are those which appear on the manuscripts.


Contents:
The majority of these lectures were delivered to undergraduates, but the course in Advanced Cytology and Fine Structure (A.40, A.42) was intended for research workers as well as final year undergraduates.
All the lectures are in manuscript, usually fully written but very occasionally in note form. They show evidence of frequent and extensive revision; often large parts of a lecture world be discarded and only a few pages retained to be included in the re-written version. Baker kept some of his old notes, but only those that contained points of continuing interest, so that this collection is for from complete.

SECTION C MICROSCOPY AND MICROTECHNIQUE  [no ref. or date]

Arrangement: The papers are presented as follows:
C.2 - C.20 Notes for lectures and practical classes in microscopy
C.21 - C.27 The electron microscope; notes and lectures
C.28 - C.43 Notes for lectures and practical classes in microtechnique
Within each section the material is arranged chronologically as far as possible.


Administrative history:
Baker's interest in and involvement with this field is reflected by the fact that he was joint editor of the Quarterly Journal of Microscopical Science, 1946-64, and President of the Royal Microscopical Society in 1964 and 1965. His book, Principles of Biological Microtechnique was published in 1958.

Contents:
The Cytology notebooks (A.2 - A.17) show considerable evidence of work in microscopy, particularly in the field of phase contrast microscopy and investigations of the function of the eye as an integral part of the light microscope. There is also a notebook on photomicrography (C.1) containing a record of constant efforts to improve and regulate the quality of photographs produced from microscopical slides.
The majority of these lectures and classes were for undergraduates, the only exception being the lectures on electron microscopy (see C.24) which from 1967 were restricted to graduates, although Baker did experiment with a one-day course on electron microscopy for undergraduates in October 1969 (see C.25).

[no title]  CSAC 69/7/79/C.1  1941-1967


Related information: There are also a few observations on photomicrography scattered throughout the notebooks on Cytology (see A.2 - A.17).

Contents:
Notebook labelled 'Photomicrography 2' covering the years 1941-67, and containing records of experiments to ascertain the best conditions for photographing microscopical slides.

The electron microscope: notes and lectures,  CSAC 69/7/79/C.21-C.27  1961-70


Related information: (See CSAC69/7/79 C.23).

Administrative history:
These lectures and demonstrations were designed to teach students the basic principles of electron microscopy and to prepare anyone who was interested for training as an electron microscopist. Until 1966 the course was for Final-year undergraduates and research students, and very little material from this period survives. From 1967 it was restricted to graduates and there is a complete set of notes for 1968 and 1969.
The Zoology Department acquired a new electron microscope, the EM6B, in 1965. Baker was in charge of electron microscopy in the department from autumn 1967, after his retirement, and he was active in ensuring that research workers were given the opportunity to take the best possible advantage of the new instrument
