This article argues that James Mill's immersion in Presbyterianism inspired an aversion to hierarchical government and a bias in favour of the Church of Scotland. These views are discernible in Bentham's Church-of-Englandism. Bentham argued for disestablishment on principle but, praising the Scottish Church as a , omitted the Kirk from his church reform manifesto. His position on disestablishment, however, and his endorsement of Presbyterianism were aligned with a voluntaryist strain of Presbyterian ecclesiological theory; Presbyterian dissenters and Benthamite Radicals began to protest against the Kirk's established status. Underpinned significantly by Presbyterian tradition and laced with Benthamic influence, a radical voluntary campaign emerged in Scotland which sought to dismantle the old order and usher in a new era of political democracy and religious voluntaryism. Radicalism in Scotland was not solely characterized by the which J. C. D. Clark believes defined Benthamite ideology; Benthamism, it transpires, was not straightforwardly secularist

Two-photon excitation laser scanning microscopy was used to image human, porcine, and rabbit nasal septal cartilage. TPM provides optical sections of thick tissue specimens in situ without the use of exogenous dyes or need for tissue fixation. The cartilage tissue was imaged using near-infrared light generated by a mode-locked titanium/sapphire laser that was raster-scanned and coupled to an inverted microscope. Absorption of two photons by endogenous molecules and subsequent fluorescence was filtered to specific spectral bandwidths and detected with photomultiplier tubes. Two-photon stimulated fluorescence was detected with photomultiplier tubes optimized to specific spectral bandwidths. Signal intensity corresponds to the concentration of fluorophores, principally NADH, NADPH, and flavoproteins hence providing a means of redox imaging the cellular metabolic state. Specimens were scanned from the surface to a depth of about 150 μm. Image size was 50 × 50 μm with a diffraction limited pixel size of 0.4 μm. Cell membranes, nuclei, and matrix structures were identified in human, pig, and rabbit tissues. TPM provides a means to study three dimensional chondrocyte structure and matrix organization in situ at substantial depths, and permits longitudinal examination of cultured tissue explants without the need for exogenous dyes, tissue preparation, or fixation.
