periods immediately following prolonged men- 
tal work over periods preceding it. . 
Dr. Livingston Farrand read a paper on 
‘Basketry Designs of the Salish Indians.’ The 
paper was a contribution to the solution of the 
problem of the evolution of decorative art and 
particularly of the question of development of 
geometric patterns from realistic portrayals of 
natural objects. Attention was confined to the 
basketry designs of the Salish Indians of British 
Columbia and western Washington, which ex- 
hibit certain peculiarities marking them off 
rather sharply from the designs used by neigh- 
boring stocks. It was shown that while the 
adjacent tribes in the Northwest make use al- 
most exclusively of animal designs, and their 
conventionalism is of a unique nature and not 
geometric, the tendency of the Salish decora- 
tions, on the other hand, is entirely in the di- 
rection of extreme geometric conventionaliza- 
tion and the use of animal motives is not pre- 
dominant. The questions of variants and of 
convergent evolution in designs were discussed, 
and the points made were illustrated by the ex- 
hibition of a large number of designs taken 
from the baskets collected by the Jesup North 
Pacific Expedition from the region under dis- 
‘cussion. 
C. H. Judd read a paper on ‘Movement and 
Consciousness.’ Reference was made to the 
recent psychological discussions which have 
emphasized the importance of movement and 
motor nervous processes as conditions of con- 
sciousness. It was pointed out that just as 
psychology must look for the conditions of sen- 
sation elements in non-psychical processes, so a 
careful analysis of the facts of perception force 
us to look for the represented factors and for 
the synthetic activities in non-psychical con- 
ditions. In support of this position examples 
were cited in which the representative factors 
were not capable of conscious revival even with 
concentrated attention, and it was shown that 
synthetic activities become progressively less 
conscious the more complete and immediate the 
process of perception becomes. Finally, the 
attempt was made to discover in the facts of 
movement and in the nervous processes which 
follow the reception of sensory stimulations, the 
conditions of perceptual synthesis and the con-

ditions which make possible present effects of 
past experience without complete or even par- 
tial revival of any sensory factors, either as 
revived sensations or as repeated sensory stim- 
ulations in the nervous system.

DISCUSSION AND CORRESPONDENCE. 
RECENT WORK ON COCCID#. 
THE writer was away from his office and 
without access to current literature for most of 
the summer just passed, and only recently has 
seen in SCIENCE for July 21st (pp. 86-88), the 
reply of Professor Cockerell to the article en- 
titled ‘Sources of Error in Recent Work on 
Coccide’ (SCIENCE, June 16, 1899, pp. 885- 
837). The article last cited was written with 
no other intent than to point out, with the hope 
of benefiting the future literature on the sub- 
ject, certain sources of error which were being 
rather emphasized by some of the more recent 
work on scale insects. To avoid personal fea- 
tures, the enumeration of examples was reduced 
to a minimum and the chief offenders were not 
pointedly indicated. That some check of this 
sort was needed is evident enough to any one 
familiar with the literature, and is further 
shown by the writer’s having received, since 
the publication of the article cited, letters 
thanking him for his action from several of 
the leading entomologists of this country and 
oral thanks from a good many others, not to 
mention such editorial approval as that in the 
American Naturalist for September, 1899. 
Professor Cockerell’s reply serves two very 
useful purposes. First, it does what the writer, 
through a perhaps ill-advised sense of courtesy, 
failed to do, namely, indicates the real and 
chief offender, who now comes to the front and 
courageously announces, ‘Iam the man!’ In 
the second place, it enables him to point out 
definitely the character of work which had 
previously been referred to in very general 
terms out of consideration for the persons con- 
cerned whose work in the main it was not 
wished to disparage. 
The opening remarks of Professor Cockerell, 
relative to his eight years experience in Coccidz, 
are rather regrettable in view of some of the
