The C; abundance distributions for laser vaporization into a pulsed He stream reported by Hahn et al. (Chem. Phys. Letters 130 (1986) 12) in which C, was not special are here contradicted by observation of a C; distribution by laser vaporization where C,-, IS prominent. ' Robert A. Welch Foundation

✦ Synopsis
Charged carbon clusters (Ch and CR; N = 9-87) have been produced by growth from laser-generated carbon vapor in a helium flow channel, without the aid of subsequent laser ionization/attachment.
The resulting abundance distributions therefore reflect relative cluster stabilities, rather than the consequences of specific photophysical processes. Under all conditions, the N F 60 magic number is reproduced in the Ch distribution, while these and other observed numbers are not seen ln the C&I distribution.

Immunohistochemistry is used to demonstrate histamine-immunoreactivity in the CNS of spiders. We found histamine-immunoreactivity in the photoreceptors of different spiders. Therefore, we suggest that histamine is a neurotransmitter of photoreceptors in all arthropods, since it is also known to occu
