I should say that it is certainly a circumstance of rather rare oc- currence ; but it is worth remarking, that it may be artificially produced by adding to the specimen some coagulating re-agent, which speedily solidifies a film of albuminous plasma around the nuclei, and thus produces very good imitations of cells. The epithelium of the thyroideal cavities often assumes the form of small vesicles larger than the nuclei (see Jigs. 736, 737, 738.), and easily distinguished Fig. 736. o.
