Catalogue of Scientific Papers. Fourth series 
(1884-1900). Compiled by the Royal Society.

Tue fourth series of the Royal Society’s Cata- 
logue of Scientific Papers, of which the present 
is the first volume, comprises the titles of papers 
published or read during the period 1884-1900, 
and concludes the work undertaken by the Royal 
Society. The catalogue thus completed will con- 
tain titles of papers for the whole of the nine- 
teenth century. The continuation of the work is 
now in the hands of the authorities of the Inter- 
national Catalogue of Scientific Literature, which 
deals with the titles and subjects of papers pub- 
lished after the end of 1go0o0. 
This volume contains 11,551 entries of titles 
of papers by 2001 authors with the initial A, and 
51,720 entries of papers by 6928 authors with the 
initial B, making a total of 63,271 entries by 8929 
authors. 
A list of the 1555 serials which have been ex- 
amined for the preparation of this section of the 
catalogue, with the abbreviations used for their 
titles, is given at the beginning of the volume. 
The complete risk of printing and publishing 
the Catalogue of Scientific Papers and the Subject 
Index has been undertaken by the Cambridge Uni- 
versity Press, and we echo the hope of the Cata- 
logue Committee that the circulation of the 
volumes throughout the scientific world will be 
large enough to prevent financial loss.

The Peregrine Falcon at the Eyrie. 
In the notice of Mr. Heatherley’s ‘‘The Peregrine 
Falcon at the Eyrie’’ (Nature, August 6,-p. 586), 
that author is quoted for the previously ** unrecorded 
fact that after the first few days the falcon turned 
over to the tiercel the duties of her sex, spending his 
time abroad hunting and bringing the quarry to 
the tiercel, who remained at home to feed and look 
after the young.’’ This sentence in its wording 
appears to treat the falcon as male, the tiercel as 
_ female; the reverse being, however, the correct use 
of these terms. As Harting (‘‘ Birds of Shakespeare,” 
p. 52) says: ‘‘By the falcon is always understood 
the female, as distinguished from the tercel, or male, 
of the peregrine or goshawk.”’ 
W. E. Hart. 
Kilderry, Londonderry, August 7. 
Mr. Harr is quite correct. The term ‘‘tiercel” 
has always been applied to the male peregrine falcon, 
cf. Newton’s ‘“‘ Dictionary of Birds”’ et passim. The 
notice in which the quoted sentence occurs was con- 
tributed from the reviewer’s sick bed, and he is 
only now aware that a point of interrogation after 
‘his’? and before ‘‘time,’’ which was in his original 
draft, had dropped from his MS. and its omission 
had escaped him in the proof.

PRACTICAL EDUCATION.! 
HE title of Mr. Legge’s book is suggestive 
of a painting in the University of Bologna, 
in which Science is represented by a female figure 
with eyes in each of her extended hands. We 
are so apt to speak of “seeing”? when we mean 
“perceiving” that we forget that the blind can 
see with their hands, and that science through- 
out the centuries has achieved most of her tri- 
umphs by the knowledge acquired by means of 
hand-work. It was early explained that the chief 
educational advantage of manual training was to 
exercise the hand from childhood as an instru- 
ment for acquiring knowledge, and so to create 
an additional perceptive sense. 
Since the years 1887-1890, when hand-work 
was first introduced as a scientific experiment into 
elementary schools, and was then proved to be 
the means of stimulating the intellectual activity 
of children, making them more alert in all other 
studies, the advances in this new educational de- 
parture, if not rapid, have been unbroken, and 
have been carried forward in many _ different 
directions. The recognition of the value of 
manual work in the education of children is now 
very general. Nevertheless, Mr. Legge has de- 
voted some of the few pages of his letterpress in 
answering those opponents who, in the early 
history of the movement, charged its advocates 
with infringing the principles of elementary edu- 
cation, with trenching on technical instruction 
and prematurely encouraging vocational teaching. 
Mr. Legge has successfully refuted all these 
arguments. In the chapter of his book headed, 
“The Growth of an Idea,” he has not attempted - 
to give anything approaching to a history of the 
movement, or he would have referred to those 
early efforts which in 1890 induced the then Edu- 
cation Department to include in the Code of that 
year regulations for the teaching of hand-work 
under conditions carrying a Government grant. 
Indeed, the few short chapters of his book, al- 
though well worth reading, are not intended to 
add anything to what may be found in other 
treatises. In his own words, “The letterpress is 
here simply to explain and lead up to the illus- 
trations,” which, he states, are designed to give 
the general public a view of the practical side of 
the instruction now provided in schools. 
These illustrations, more than four hundred 
in number, admirably fulfil that purpose. They 
show how varied may be the exercises which are 
now practised in the conduct of the modern side 
of elementary schools, and experience has fully 
borne out his contention that these exercises are 
all, or nearly all, equally efficient in stimulating 
the intelligence of children. Indeed, the value of 
manual training is shown to depend far more on 
the method of instruction than on the materials 
employed, or on the models that are made. The 
illustrations, of which this book largely consists, 
show children occupied with educational exercises 
in such diverse materials as wood and metal,
